Loan and Project Summary

Borrower: Republic of Indonesia

Amount: US$156 million equivalent

Terms: Repayable in 20 years, including 5 years of grace, at thestandard variabLe rate.

ProjectDescripcion: The main obiectives of the project are to increase food

production an some 59.340 ha, stimulate employment in theproject area. control damaging floods in rural and urbanareas, supplement water supplies for some 300 villages andtowns, generate 74 GWh of power which would be fed into thenational grid and improve water management in the projectarea. The project includes: (a) construction of the KedungOmbo Dam, appurtenant structures, diversion works, a hydro-power plant (28.5 MVA) and associated transmission line (30km, 150 kV) and three micro-hydropower plants (about 1.8 MVAeach) and associated transmission lines (20 kV); (b)improving existing irrigation (34,240 ha) and constructingtwo new irrigation systems (25,100 ha); (c) establishing aflood warning and water monitoring system for the dam andirrigation operations; and (d) provision of technical assis-tance for: Mi) training in dam construction and safetyinspection and in reservoir operations; (ii) design ofirrigation works serving 121,300 ha from the Jatigede Dam(West Java); (iii) surveys for updating classification ofland for tax purposes to improve cost recovery; (iv) surveysfor monitoring resettlement and compensation payments; and(v) studies for soil and water conservation. AlthoughIndonesia is now largely self-sufficient in rice, steadyincreases in national rice consumption and the very limitedscope for expanding the irrigated area on Java make it vitalfor the country to intensify food production by augmentingdry season water supplies through the construction ofmultipurpose dams. The increase in cropping intensity thuspermitted would also have a substantial impact on raising theincomes of smallholders and landless laborers in an areawhere more than 60Z of the population has incomes below theabsolute poverty line, about a third of farm households arelandless, and unemployment is high. The main project risksare delayed land acquisition and inadequate operation andmaintenance (O&M) of the irrigation systems. However, landacquisition has already begun and Government has agreed to aschedule and has given assurances on adequate funding for

this purpose. Shortfalls in O&M budgets are not expected inview of assurances obtained for adequate funding andGovernment's willingness to fund O&M costs for irrigationprojects from its development budget, and from increasedallocation of land tax revenues collected at the local Level.

I. BACKGROUND

General

1.01 The Government of Indonesia (GOI) has requested assistance for theconstruction of the Kedung Ombo multipurpose dam, one the major waterresource developments in the Jratunseluna River Basin in Central Java. Thedam will provide irrigation water for (a) 25,100 ha of new 2 rrigation systemsin the Klambu Kanan (Juana) and Sidorejo (South Crobogan) - areas and 2b)34,240 ha in the Sedadi (Upper Sedadi) and Klambu Kiri (Lower Sedadi) Iirrigation systems which at present have only wet season irrigation. Theproject will also control flood waters in che upper and lower Serang area,improve drainage and augment domestic and municipal water supplies in cheservice areas, and generate hydropower.

1.02 The Bank has been deepLy involved in planning and implementing proj-ects in the Jratunseluna Basin since the Irrigation I Project (Cr. 127-IND) in1968, under which the then largely inoperative Sedadi irrigation syscems wererepaired. Extensive tertiary development in the Upper and Lower Sedadi areaswas supported under Irrigation Projects VII and IX (Lns. 1268 and 1435-IND).Master plans for the whole Jratunseluna Basin and designs for additionaldrainage and flood procection works were also prepared under the IrrigationVII Project together with feasibility studies and designs for a dam at KedungOmbo on the Serang River and related irrigation development. The floodprotection works and drainage are being implemented under the Irrigation XIVProject (Ln. 1811-IND), while construction of the dam and related irrigationfacilities will be carried out under the proposed project. The proposedproject was prepared by PROSIDA (the special project agency responsible formost Bank-assisted projects) which has now been incorporated into theDirectorate of Irrigation II in the Directorate General of Water ResourcesDevelopment (DGWRD), assisted by consultants (Snowy Mountains EngineeringCorporation of Australia).

The Agricultural and Rural Sector

1.03 GOI's major objectives for the agricultural and rural sector areto: (a) create productive employment to raise incomes of the rural poor; (b)increase domestic food supply, especially rice, to keep pace with risingdemand; (c) expand agricultural exports, particularly of smallholder treecrops; and (d) ensure productive, sustainable use of Indonesia's land, water,and natural resources.

2/ GOI has renamed the irrigation areas.- based on the sources of water. Thenames in parentheses refer to the names of administrative areas where theirrigation systems are located.

1.04 Food crop production forms 60% of agriculturaL GDP and 18% of total(DP. Rice is the most importanc food crop. Between 1968 and 1982, rice pro-duction grew substantially in response co government interventions, includingexpansion of the irrigation network, major changes in rice growing technology,and price incentives. Production gains of other major food crops, while notso impressive as those for rice, have exceeded population growth, althoughsome crops, for exampLe corn, are encountering market constraincs.

1.05 GOI's policies in food crop production, combined with the expansionof the COI infrastructure investment program (e.g. INPRES, etc.) and thestrong linkages and multiplier effects between agriculcural incomes and otherrural industries, have had a substantial impacc on increasing incomes andlevels of living in a large portion of the rural areas. They have alsoresulted in some reduction in the incidence of rural poverty, even though thisstill remains a major probLem facing GOI. Increases in income have not beenuniformly spread, especiaLly to dryland rood crop farmers. in many cases,inadequate infrastructure is also a contributory factor to slow growth in foodcrop output, and needs to be addressed through further investments in ruralroads, etc.

1.06 The Bank, in cooperation with GOI, has undertaken a series of sectorstudies related to food crop production, the most recent of which are PolicyOptions and Strategies for Major Food Croos (October 1982, Report 3686-IND)and the Irrigation Sector Review: An Issues Paper (October 1982 and updatedin May 1984) which reviewed the irrigation work program and budget included inthe GOI Fourth Five-Year Development Plan (Repelita IV) for the period1984-88.

The Irrigation Subsector

1.07 Irrigation and Rice Production. During 1970-83 rice production grewfrom 13.1 million tons to 23.3 million tons. Production increased at about4.9% per year during 1970-81, but slowed to 2.2% per year from 1981 to 1983mainly due to droughts. Rice production increases between 1970 and 1981resulted from increases in the harvested area (25%) and yield increases(75Z). About 16% of the production growth can be attributed solely to expan-sion and improvement in irrigation, about 9Z is due to improved rice varietiesand fertil ,er use, and about 75% is due to the joint interaction of thesevariables.-

1.08 Rice consumption steadily increased at 4.5% per year between 1970and 1981, of which 2.3% p.a. was due to population increases and 2.2% p.a. toincome, price and other effects. In 1980 and 1981, Indonesia became largelyself-sufficient in rice, and rice imports plunged from 2.0 million tons in1980 to 0.3 million tons in 1982. GOI buffer stocks increased to 2.3 millionin 1981. Successive droughts reduced production in 1982 and 1983, forcingGovernment to import some 1.3 million tons of rice in 1983 and 0.3 million

3/ Source: Indonesia - Policy Options and Strategies for Major Food Crops,Report No. 3686b-IND, April 1984.

- 3 -

tons in 1984. The 1984 crop is tentatively estimated at 25.5 million tons,and buffer stocks have increased once more to some 3 million tons. It isexpected that for most "average rainfall" years rice production will meetdemand, provided the present rate of irrigation development is maintained.

1.09 In the future, improved rice variecies and fertilizer use are likelyto play a lesser roLe in increasing Indonesia's rice production. The use ofhigh yielding varieties (HYVs) is already high (about 80% of the irrigated andwetland crop) and is unlikely to expand beyond 90X in 1990. Several tradi-tional varieties are preferred for taste and ceremonial reasons, and arebetter adapced to difficult growing conditions such as saline. flooded orwater-short areas. Fertilizer use is also high. particularLi on 'ava whereabout i35 kg of nitrogen and 50 kg of phosohate per hectare are now applied.There is evidence chat nitrogen applications above this would be -wasted andcause crop iosses due to lodging and greater insect damage. With such alreadyhigh fertilizer and HYV use, future yield increases will depend primarily onimproving the quality of irrigation and water management, and expandingirrigation to exiscing dryland areas.

1.10 Strategy for Water Resource Development. GOI's irrigation sectorinvestments include irrigation works to sustain self-sufficiency in rice;swamp reclamation for transmigration; and river control works to developmultipurpose use of water resources for irrigation, municipal water supply,flood mitigation, and hydropower. The Bank sector work assisted by GOIcovering the Repelita IV plan period (1984-88) concluded that the followinginvestment program would be justified:

(a) Construction of 0.5 million ha of ongoing rehabilitation, and 0.2million ha of new irrigation works including medium (sedang) andlarge-scale (khusus) systems. New rehabilitation projects andtertiary network construction of 0.6 million ha would be pursued,together with 0.27 million ha of new small (kecil), medium (sedang)and large-scale (khusus) irrigation works. Construction of at leasttwo major dams on Java to supply water for irrigation intensifica-tion will be included as part of the program. These irrigationworks would enable GOI to maintain self-sufficiency in rice produc-tion, which requires an annual growth rate of 3.5% (harvested areagrowth of 1.4% and yield growth of 2.1%);

(b) Construction of 0.1 million ha of tidal swamp reclamation (grossarea), and a further 0.3 million ha of new reclamation works toaccomodate 20,000 to 25,000 transmigrant families per year. Anadditional 0.1 million ha of already settled inland swamp area needrehabilitation and improved water control; and

(c) Construction of river control and improvement works (levees, dams,etc.), and volcanic debris control in about 20 river basinsthroughout the country for more efficient multipurpose use of water.

1.11 Multipurpose Use of Water and Dam Construction Program. Java hasthree million ha under irrigation (60X of all irrigated areas in Indonesia),and very little scope (about 16,O000 ha) for new irrigation schemes. Basic

-4-

rehabilication of che Javanese schemes is almost completed. Crop productivitycould, however, be further increased through intensive system upgrading coimprove operations and facilitate maintenance; construction of better tertiarynetworks; and augmentation of dry season w.ater supplies from multipurposestorage dams. The increase in cropping intensity thus permitted would have asignificant impact on raising the incomes of very small farms (0.1 to 0.3 ha)and the employment of surplus landless labor.

1.12 Water resources must also be developed for meeting municipalsupplies, hydropower and flood control. Excensive floods in the i980i'81 and1982/83 wet seasons caused widespread disruption of road transportation anddamage to both agricultural and urban areas (e.z., Semarang in CertralJava). Limited municipal and industriaL water suDpLies for key cities(Jakarta, Semarang, Surabaya. etc.) have sLowed down their development. Sincegroundwater in these sites is not promising, water storage through dams is theonly rationai alternacive to increase water supplies.

1.14 GOI started construction of two dams in late 1982, and has detaileddesigns for nine others, the construction of which is phased to meet actualrequirements. At present, COI places highest priority on the Kedung OmboMultipurpose Dam Project on Java in view of its major irrigation benefits inan area now largely without dry season water but subject to flooding in thewet season. The proposed dam wouLd also generate power and develop municipalwater supplies for major towns in the commuand area (Demak, Grobogan, Pati)once flows are controlled in the Serang River.

1.13 Investment Needs. The indicative irrigation program and relatedinvestments in water resources developr*nt are estimated to cost about Rp 4.5trillion (US$4.1 billion) at current costs (see Table 1.1). About one-thirdof this amount, equivalent to the foreign exchange cost of foreign-assistedprojects, is expected to be financed from external loans. This is somewhathigher than the share (about one-quarter) financed from external loans duringRepelita III, due to the assumption that completion of ongoing foreign-assisted projects will be given priority over the next few years. As in thepast, the balance of funding will come from the Government's domesticbudget. The indicative program is 30% smaller than the planned allocationsfor irrigation and water management. This is partly due to cutbacks inphysical programs, due to the overall resource constraint and the changingrice situation. It also reflects some substantially lower unit costs, basedon recent experience with international bids for civil works contracts.During 1984/85 and 1985/86, actual budget allocations were only about 75% ofthe level required for the indicative program, and .ctual expenditures may beeven lower. Therefore, to meet the physical program some further rephasing ofinvestments will probably be necessary. This rephasing might also help smooththe projected bunching of investment costs in 1986/87.

1.15 There are a number of features worth noting in the composition ofthe indicative investment program: (a) Close to 85Z of the costs are relatedto ongoing projects, of which 77% are foreign-assisted. New foreign-assistedprojects are projected to cost Rp 384 billion while new GOI projects arelimited to Rp 293 billion; (b) The major components of the program are forlarge-scale irrigation expansion (38Z), irrigation rehabilitation (14Z), river

improvement (12%), irrigation O&M (7U), 0ood control (7%) and medium-scaleirrigation (6Z). However. aew investments show a significant reorientation ofpriorities, away from large-scale irrigation (11%) and towards flood controL(23%) and swamp programs (15%). '-i These changing priorities also reflect ashift in the regional distribution of investments. Java still accounts formore than one-half of total investment costs. However. among new projects,over 90% are located on the Outer Islands, mainly on Sumacra and on Sulawesi.

1.16 Major Constraints in irrigation development relate to improvingirrigation system operation and maintenance (O&M) and ensuring adequate costrecovery. Current standards of 0&1M of the main systems are frequently inade-quate, though GOI has consistentLy raised the level of funds allocated forsuch purposes, and has decided in FY84/85 to slow the rate of new irrigationconstruction and divert development funds to improve O&M standards. BanKassistance in O&M is designed to improve the organization and training of theprovincial services which are responsible for all O&M activities and to deve-lop and demonstrate new techniques (Irrigation XVII, La. 2119-IND and SecondProvincial Irrigation Development Project, Ln. 2375-2ND). Cost recoverythrough the IPEDA (land tax) s an efficient mechod of colLection, and linkslevies to the productive capacitv o- -arm Lands. WhiLe capital cost recoveryis less than 10%, this is an equitabie position consisEent with che povertyand small farm sizes of most beneficiaries. However. reclassification ofnewly irrigated lands and raising of ..ew Land taxes have often been slowbecause of the lack of coordination within the various agencies. Assuranceswere therefore obtained from Governmenc that reclassification of Landbenefitting from the proposed project and collection of increased IPEDA taxeswill be carried ouE in a timeiy manner (para. 6.07). Bank assiscance willalso seek to introduce a more direct linkage of IPEDA levies to O&Mallocations and to ensure that O&M funds are spent effectively.

The Role of the Bank

1.17 Since 1968, the Bank has provided US$1,018 million for irrigationprojects in Indonesia. The earliest projects were designed to repair majorsystems to quickly increase rice output. Later projects provided additionalrehabilitation of existing systems, drainage, flood protection, and tertiarynetworks. The most recent projects include measures to strengthen planning,programming, and budgeting capacity and management information systems(Irrigation XV - Cr. 995 and XVI - Ln. 2118), and to build up the capacity ofprovincial irrigation services in East Java Province (Irrigation XVII - Ln.2119), and in eight other provinces (Second Provincial Irrigation Development- Ln. 2375).

1.18 During Repelita IV, the Bank's involvement in the sector willemphasize institution-building and address persistent sectorwide problems suchas operation and maintenance standards. Lending will focus on:

(a) strengthening of national, and especially provincial, irrigationservices, and improving their operation and maintenance performance;and

(b) a small number of technically complex projects or projects whichpresent difficult economic choices, or in which Bank participationcan mobiLize significant cofinancing. Besides the proposed project,these include the West Tarum Canal for irrigation and the Jakartawater supply, and the Jatigede Multipurpose Dam project.

four of them 4 and a follow-up .mpact Evlluation Reporr on .he first project(Cr. 127-IND) was released in July 1983.-;

1.20 The most serious implementation problems were construction delaysand cost overruns. The delays arose because of GOI's then cumbersome localbidding, contracting and fund reLease procedures, and shortages of localfunds. Cost overruns were due to additional quantities of work required afterdetailed design, and increased unic costs due to rapid inflation and construc-tion delays. However, cost increases were more than offset by higher ricefprices, and economic rates of return are expected to exceed 40X. Other prob-lem areas include the need to improve operation and maintenance services (O&M)at provincial leveLs; to provide cechnical and administrative support to wateruser associations; and to promote efficient water use. These Droblems arerecognized in the strategy adopted for Bank assistance (para. 1.18) and havebeen used in the planning and design of this project.

1.21 Disbursement Performance. Disbursements currentlv run at about 73%of appraisal escimates. Performance has improved (disbursements -vere below61% in FY82) through more intensive supervision by Residenc Bank staff, accel-erating start-up activities and disbursing against statements of expendituresfor small civil works contracts. In addition, consulting service needs areusually agreed with the Bank prior to loan negotiations, and civil works forthe first year's construction are usually tendered and contracts negotiatedprior to loan effectiveness. Together with other continuing Bank assistanceto accelerate contracting procedures and improve the domestic constructionindustry, these measures appear to be progressively reducing implementationdelays.

II. THE PROJECT AREA

Background and Location

2.01 The proposed Kedung Ombo Multipurpose Dam and Irrigation Project ispart of the Jratunseluna basin development and is located in the flood plainsof the Serang River and its tributaries, about 75 km east of Semarang on thenorth coast of Java. In 1971, DGWRD assisted by consultants (NEDECO) prepareda master plan for the development of the water resources of the rivers of theJratunseluna basin, which, together with later studies, identified thefollowing priority schemes: (a) flood mitigation works (levees, etc.) alongthe Jragung, Tuntang and Dolok Rivers; (b) rehabilitation of irrigationschemes served by the Jragung, Dolok, and Tuntang; (c) tertiary irrigationnetwork construction in the Tuntang, Jragung, and Sedadi areas; (d) floodprotection and drainage in the Lower Serang and the river systems that feedthe Serang from Mount Muria, and drainage of the swamp areas in the Juana

'Valley; and (e) construction of the Kedung Ombo Dam on the Serang River andthe Glapan Barrage on the Tuntang River to improve water supplies forirrigation and for flood mitigation.

2.02 The Bank has been involved in the Jratunseluna basin developmentthrough the following projects: Irrigation I (Cr. 127-IND), Irrigation VII(tLn. 1268-IND), Irrigation IX (Ln. 1435-IND), Irrigation XI (Ln. 1579-IND) andIrrigation XIV (Ln. 1811-DID). The irrigation I Project rehabilitated themain irrigation system in tr:e Serang area. Extensive tertiary development inthe Sedadi (Upper Sedadi) and Klambu Kiri (Lower Sedadi) areas took placeunder Irrigation VII and rX, and main and some secondary drainage in the LowerSerang and Juana Valley areas is being improved under Zrrigation :IV. 'fncontrast to the Bank's eariier activities which concentrated on improving theirrigation syscem and flood control, ,he prouosed Kedung Ombo projec. isintended to enhance water availability through construction of a dam on theSerang River in order to ex?and irrigation to the currentLy rainfed areas ofSidorejo (South Grobogan) and Klambu Kanan (Juana Valley) and to the alreadyirrigated Sedadi and Klambu Kiri areas, where the system will be improved (seeTable 2.1). This will greatly increase the cropping intensity of thepreviously rehabilitated irrigation systems and reduce floods.

Serang and main drainage for Klambu Kanan (Juana Valley).

2.03 The net area for development (59,340 ha) comprises Sidorejo(6,100 ha) on the right bank of the Serang River near Purwodadi, Klambu Kanan(19,000 ha) further downstream on the right.-bank, and the Sedadi and KlambuKiri irrigation area (34,240 ha) situated on the left bank, running fromPerawangan down to the coast (see Map 18555). The project area is comprised

of parts of four kabupatens (discricts) - Demak, Kudus, Pati and Grobogan -and 22 kecamatans (subdistricts) with 308 villages. The area is well servedby air, rail and road transport, and port faciLities in Semarang.

Climate and Soils

2.04 The climate is tropical and monsoonal. Mean annual rainfall isabout 2,000 mm, with 85% occurring in the wet season (October-November toApril-Hay). Mean monthly evapotranspiration exceeds rainfall in the June-October dry season. Most rainfall is localized, short duration, and of highintensity. This underlies the need for flood protection. drainage andsupplementary irrigation co achieve satisfactory Leveis oi oroduction in theflood plains of the Serang aiver system.

2.05 The four project ayeas (Sidorejo, Klambu Kanan, Sedadi and KlambuKiri) have different soi s ° buC are ai. suited zo intensive rice croppingand several secondary crops. The Sidorejo irrigation area is a relativelywell drained flat river plain ac about 20 m above mean sea level (MSL). Dueto the flat grades and Lack of drains, shallow inundation occurs in somelocations for up to 24 hours following heavy rain. About 5,000 ha of lower-Lying land is subject Eo inundation by the Serang River flood (every fiveyears), but total crop Loss occurs only on about 250 ha. The soils arepredominantly grumosols which are suited for intensive rice growing and fordry season secondary crops. The Klambu Kanan area is located on the very flatalluvial flood plains of the Babalan-Juana River at an elevation of 2-14 mabove KSL. These plains were built up rapidly by sediment deposition, due tothe construction of the Wilalung diversion structure in 1918 and subsequentdiversion of Serang River flows to the Juana Valley. The bulk of the area issubject to regular flooding and poor drainage and is classified as permanentswamp (see Map 18555). Works in progress under che Irrigation XIV project(Loa'n 1811-IND) will have a significant effect in improving and extending thecropping area in Klambu Kanan. The Sedadi and Klambu Kiri areas have alluvialdeposits of volcanic origin, well suited to intensive rice cultivation.

Existing Irrigation Systems

2.06 A large portion of the lower Serang basin, including Sedadi andKlambu Kiri, is covered by irrigation systems. In the Klambu Kanan area,minor streams are diverted to irrigate small areas scattered along the foot-hills in the wet season. The Sidorejo project area has no irrigation.

2.07 The Sedadi irrigation system (previously known as the Glapan-Sedadi)is the largest in the area. Most of the area receives irrigation water fromthe Serang River through an intake structure (the Sedadi Weir) constructed in1886, and remodelled in 1922 and 1976. There are four distinct irrigationservice areas. Two form the Sedadi area: (a) Serang (about 6,880 ha), servedby the secondary canal from the Sedadi River and a canal from the TuntangRiver at Glapan which provides an unreliable supply of excess water from the

Tuntang. M4ost of :'.e area receives a fairlv reliable wec season water suppLy,but dry season flows are adequace only for abouc 25Z of the area, and (b)Tuntang-Serang (about 7,030 ha). supplied mainiy from the Sedadi WeirsuppLemented with excess water .rom tnie runtang River when avaiiable. Anadditional pump intake for che main canal was constructed around 1970 atPondok on the Serang River. slightly upstream of the Wilalung diversionstructure, 29.4 km downstream from the Sedadi Weir. The Pondok intake wasbadly silted up in 1973 and has not been used since. About 70% of theTuntang-Serang area has a reliable water supply for wet season rice but only25Z receives water in che dry season.

2.08 The other cwo areas fail in Klambu Kiri: (a) Pelayaran (about10,560 ha) which recei7es water at the downstream end of the Si canal but isLargely dependent on drainage water from the Tuntang-Serang area, fed into thePeLayaran canal, about 10 km downstream from its junction with Si. SuppLiesare generally inadequate, particularly in the drv season, and ase of thedrainage return flow from Tuntang-Serang causes poor drainage conditions inpart of that area; and (b) Wedung (abouc 9,770 ha), which is supplied from theiower section of the Serang or WuLan Rivers by means of a oumping station con-structed at Karanganyar in 1968. Serious siltation problems and pump operat-ing difficulties hamper a regular water supply. About 75Z of the Klambu Kiriarea has wet season irrigation buc only 25% has dry season water.

2.09 The structures of the Sedadi and Klambu Kiri system are, in general,sound but several gates need replacing to receive water released from thedam. Tertiary networks have been designed for the entire area, but have beenconstructed only in Serang and Tuntang-Serang. ConstructiGn in the lowerparts of the Pelayaran and Wedung areas has been postponed until regularflooding is prevented there, following completion of flood protection anddrainage works under the Irrigation XIV Project (Ln. 1811-IND).

Power

2.10 Two power systems operate in Central Java under the PerusahaanListrik Negara (PLN, GOI's power authority): the Ketanger system to the westand .the larger Tuntang system in the east. In addition, there are manyisolated diesel and a few micro-hydro units. The total installed generatingcapacity in Central Java in 1984 was about 483 MW, comprising 80 MW (16.6Z) ofhydro, 300 MW (62%) oil-fired steam, 84 MW (17.5%) gas turbines and 19 MW(3.9%) of diesel capacity. The total installed capacity has almost doubledsince 1979. The total firm capacity is about 250 MW (50%).

2.11 Demand for power in Central Java during 1978-83 increased by 26% ayear in peak, and 20% a year in energy, sales. With such dramatic increases,it is expected that gas turbines and steam station capacity will be fullyutilized by the late 1980s. Any hydro station with even secondary power wouldprove to be very economical in saving fuel costs from thermal stations. Thepower component of the proposed project would help meet some of these require-ments.

Town and Village Water Supplies

2.12 Protected water supplies are available only in the towns of Kudus,Purwodadi, Demak and Pati, but only about 152 of the urban population isserved by these supplies. In ruraL areas, the onlv source of water is fromsprings, wells, rivers and canals, and less than 10% of the rural populationhas access to a protected water supply. Toward the coast, aLmost the entiredomestic water supply is untreated canal or river wacer. which is in shortsupply and becomes heavily polluted as che dry season progresses. Under theproject, domestic, municipal and industrial water wouLd be augmented from thedam to benefit people in the towns of Demak, Grobogan and Pati. Municipalwater will be treated at various points along the canais. GOI, assisted bythe Asian Development Bank (ADB), is currently identifying Ehe necessary watersupply investments, and their construction will be coordinated with thisproject.

Agriculture

2.13 Some 69% of the gross project area of 82,600 ha is under rice orsecondary crops and 31X (25,310) is secttlements, dry fields, swamp lands, etc.(Table 2.2). About 48% (27,350 ha) of the rice fields are irrigated and 52%are rainfed wetlands (sawahs). About 50% of the rainfed ricelands are subjectto floods from the Serang River, but chey will largely be protected by drain-age and flood mitigation works now being constructed under the Irrigation XIVProject (Ln. 1811-IND). The same project will drain the 2,100 ha of permanentswamps in Klambu Kanan, after which they will be reclaimed.

2.14 The four project areas have varied levels of agricultural develop-ment depending on the availability of water, drainage and flood protection.In Sidorejo, production is entirely rainfed. Cropping intensity is high(265%), mostly in maize and soybeans, but rice yields are low due to rainfedconditions and the lack of irrigation. Klambu Kanan has wet season irrigatedrice on some 2,550 ha, and rainfed rice on about 15,300 ha, of which 10,000 haare affected by floods. The rainfed area will increase to about 17,600 ha asa result of drainage improvements under the Irrigation XIV Project. In thedry season, irrigated rice is planted on about 1,000 ha, and maize and soybeanare planted over about half of the wet season cropped area. Klambu Kiri hassome 20,400 ha of wet season rice, of which 12,100 ha are irrigated and8,300 ha are rainfed. Poor drainage on about 60% of the rainfed area is beingcorrected by the Irrigation XIV Project. At present, dry season rice croppingis possible on only about 500 ha due to the severe shortage of irrigationwater. In low drainage areas, half the fields are intercropped with maize andsoybean/mungbean, and in the dry season, chili, cucumber and watermelon aregrown. The Sedadi area has about 13,9G0 ha of wet season rice, 90% of whichis irrigated. Dry season rice is grown on about 6,300 ha, and triple croppingis possible near the Sedadi weir on about 1,400 ha. Maize and soybean areplanted on about a third of the area which does not have a second rice crop.

Farm Size and Land Tenure

2.15 The Agricultural Census in 1983 indicated that farm land was distri-buted among some 87,400 farms in the project area (Table 2.3). Almost 55% offarms are less than 0.5 ha, which in conjunction with the high population den-sity refleccs the pressure on land resources. Farm sizes cend to be smallerin Sidorejo, particularly near the urban center of Purwodadi, -where 63% offarms are below 0.5 ha. Almost 60% of farms are owner-overated. 31% areoperated by tenants and only 10% by sharecroppers. In most sharecroppingarrangements, the landlord and tenant share total oroduction, inpuc and hiredlabor costs. The tenant and his family provide their Labor. and the Landlordpays the land tax. Land values and rentals vary considerably according coproductivity and demand, and are higher in Sidorejo and Kiambu Kanan (Table2.4). The low averages for land values recorded for the Sedadi areas reflectthe poor water control and limited crop production in Klambu Kiri.

Population

2.16 In 1983, the project area had a predominantly rural population of570,600 (about 125,000 households), distributed as shown in Table 2.5. Therelatively small household size (4.6 persons) and low population growth (1.64Zper annum) are indicative of the impact of the family planning program. Theworking age group (15-59 years) represents about 54Z of the local population,although 42% of the project area population is under 14 years.

Employment

2.17 The workforce in the project area represents about 46Z of the totalpopulacion, reflecting a considerable degree of unemployment in addition tonon-pyeicipation for reasons such as schooling or household activities.Data f Eor 1982 indicate that agriculture provided employment for about 64Z(209.000) of the total employed workforce of 261,000, or some 37Z of the totalpopulation. Of the 87,000 farm households in the project area, some 33,000consist of landless agricultural laborers. The opportunity for urban employ-ment in the four major towns of Demak, Kudus, Pati and Purwodadi is limited,although the seasonal tobacco industry in Kudus employs some 35,000 people.

Health

2.18 Most health problems, as elsewhere in Java, are related to diseasescommonly associated with poor nutritional standards and environmentaL sanita-tion. The most common diseases are gastro-enteric and parasitic infections(e.g., hookworm). Of primary concern under the proposed project are thepossible effects of project construction of a reservoir and new irrigationsystems the incidence of water-borne and zoonetic diseases such as cholera,malaria - and filariasis. The high incidence of malaria in irrigation areascan be reduced by closure and draining of secondary and tertiary canals afterthe establishment of dry season crops, which breaks the continuous vectorbreeding cycle. This and other measures will therefore be taken under theproject to increase the effectiveness of malaria control programs in theservice areas (see para. 3.42(e)).

III. THE PROJECT

Objectives, Rationale for Bank Involvement and Scope

3.01 The major objectives of the project are to: (a) increase foodproduction on some 59,340 ha through irrigation, and provide additionalemployment opportunities, (b) control flooding in the upper and lower reachesof the Serang River through construction of a dam which, together with worksunder the Irrigation XIV Project (Ln. 1811-IND), will protect about 10,000 haof productive land in Klambu Kanan and 5,000 ha in urban areas; (c) supplementmunicipal water supplies for about 300 villages and towns in the irrigationarea; (d) generate hydropower, mostly secondary power, which will result infuel savings at existing thermal stations; and (e) improve water management inthe project area.

7/ Kantor Statistics, Central Java Provincial Government.

8/ About 0.11-0.5Z of the population in most of the project areas isinfected with the dominant form of malaria (plasmodium vivaz), thepreferred breeding habitat for the vector being paddy lands. In multi-cropped irrigation areas the infection rate probably exceeds 10X.

Project Details

3.04 The Kedung Ombo Dam site is located on the Serang River near thevillage of Kedung Ombo and is accessible by a 30 km all-weather road from thetown of Purwodadi. The drainage basin is 614 sq km. The selection of thesite was decided based on the availabilitv of construction materials andhydrological considerations as the most suitable to regulate che maximumquantity of water (85: of the annual flows) at the lowest cost per cu m ofwater stored. The Dam wilL be a rockfiiLirandomfill embankment with a centralimpervious core bounded by filter and gravel transition zones. rhe founda-tions consist of interbedded claystones and sandstones and are consideredsuitable for a fill type dam. The dam will be of 61 m maximum height and1,600 m crest length. The total embankment volume will be 6.3 million cubicmeters (MCM). The design crest level is Elevation (EL) 96. with a full supplylevel of EL 90. Minimum operating level is EL 64.5 below which the deadstorage is 88 MCM and above which the active storage is 635 MCM. Thereservoir surface area at maximum flood level EL 94.2 will be 60.4 sq km.

3.05 The appurtenant structures include: (a) a concrete lined diversiontunnel, 4 m in diameter and 325 m long through the right abutment of the dam,which will discharge 180 cu m/sec during the design diversion flood of a 200-year return period; (b) an ungated service spillway incorporating a 40 m longogee crest with a discharge capacity of 1,000 cu misec during a 15-day prob-able maximum flood; (c) a 250 m wide emergency spillway incorporating a2-element fuse plug embankment to prevent overtopping of the dam in the eventof an extreme flood (the estimated peak discharge during a 15-day probablemaximum flood is 4,540 cu m/sec); (d) a 51.7 m high reinforced concrete intakestructure and a 270 m long, 3.8 m diameter pressure conduit; and (e) an irri-gation outlet, branching from the pressure conduit, controlled by a fixeddispersion cone valve with a butterfly guard valve. These and other featuresare indicated in Table 3.1 (see Annex 3, Table 1 and Figure 1).

3.06 Materials sources for the dam will be as follows: (a) the rockfillfor the main cofferdam and upstream shell of the embankment will consist ofcalcarenite from a source near the town of Juwangi, situated 15 km by a newhaul road from the damsite; (b) the downstream shell of the dam will consistof randomfill of fresh claystone with interbedded sandstone, the main sourcebeing a borrow area, about 1-1/2 km from the damsite, with the balance fromrequired excavation in the emergency spillway area; (c) the impervious corewill be weathered claystone, obtained from the dam abutments, and materialremoved to expose the foundations; and (d) a 2.5 m thick filter drain con-structed against the downstream boundary of the core, as well as filterblankets and finger drains over the foundations downstream of the core, willconsist of processed andesite, brought from rock sources close to the site.

3.07 Durinz conscruction, the Serang River flow will be diverted throughthe diversion tunnel by a coffer dam approximately 30 m high. The coffer damwill be constructed in the first Piacement season and will form part of themain body of the dam. A water controi plant will be installed in the intakeof the diversion tunnel to allow for irrigation releases to existing areasduring dam construction.

3.08 An instrumentation network of piezometers. settlement gauges,extensometers and horizontal movement indicators will be inscalled to monitorthe behavior of che dam during and after the construction. The dam .sdesigned and sized to maximize irrigation, although ic has multipurpose bene-fits. The optimum dam height was decided after nvdroLogicai, geologicai, andsoil investigations and simulation studies on reservoir operations.

3.09 Water Requirements were estimated for two rice crops over the entirearea and for secondary crops for 302 of the area. The wacer requirements wereestimated using the Penman formula and crop factors developed for Java byDGWRD's Directorate of Irrigation II (DOI-II) and the International RiceResearch Institute (Philippines). Water requirements needed for the designeddry year (one year in five years) vary from 1,880 mm co 2,023 mm per year forthe various areas. The maximum water duties for which canals were designedvary from 1.35 to 1.5 liters per sec per ha (see Table 3.2).

3.10 Reservoir Characteristics and Operation. The reservoir will have anormal maximum operating water surface level (NWSL) of 90 m MSL, and minimumoperating level of 64.5 m MSL. When full (at NWSL) the reservoir willinundate 46 sq km (4,600 ha) upstream of the dam. Its normal maximum operat-ing capacity will be 635 million cubic meters (MCM). The dead storage volumeis 88 MCM. On the basis of simulation studies covering a 31-year hydrologicalcycle, the average annual inflow to the reservoir is 796 MCM of which 647 MCMwill be released for irrigation, 108 MCM released for dump power to preventspilling, and 11 MCM for urban water supply, while 10 MCM will spill over thedam (see Chart 26681). The dam thus will regulate 85Z of the upper SerangRiver flows. The reservoir will be operated to guarantee that sufficientwater is available to meet the full water requirement for a cropping intensityof 230Z with a 1% risk during the second rice crop season (50% rice crop lossfor one year in 31 years) and a 10Z risk during the secondary crop season(three crops of secondary crops lost in 31 years) (see Chart 26681).

3.11 Releases from the dam will form 34% of total cropwater requirements,with 66Z from rainfall and downstream uncontrolled riverflows (Table 3.2).Riverflows must be forecast and rainfall monitored over the service areasdaily to provide flow data for reservoir operations and scheduling of damwater. A telemetered hydro-meteorological network will be installed, linkedwith a minicomputer operation at a Water Control Center to be established forthe project at Kudus.

3.12 The power generated is essentially due to irrigation releases, andis incidencal. A totaL of 74 CWh of energy will be generated, of which peakpower of 14.6 GWh is about 10 MW for 4 hours daily for 952 of the year.

3.13 The Sidorejo irrigation system will provide irrigation and drainageto a net area of 6,100 ha within a gross area of 9,230 ha. Water will besupplied from the Kedung Ombo Dam, approximately 9 river km downstream througha gated intake in a new diversion weir on the Serang River. In addition tothe diversion weir, the project works (see Table 3.3) include 87.3 km ofprimary and secondary irrigatior canals, 46 km of inspection roads for opera-tion and maintenance of the canaLs, 18 km of secondary drains, and appurtenantstructures. The Sidorejo system will be equipped with automatedhydrotechnical gates in the main and some secondary canals and flow modulesfor all other secondary/tertiary canals over 6,100 ha on a pilot basis forimproved water management. The irrigation area will be divided into 109tertiary umits, with an average size of 56 ha net irrigable area. Thetertiary facilities will comprise tertiary and quaternary canals and drainsand minor structures for up to 8-10 ha lots. Additional access roads of 31 kmwill be constructed for better farmer access.

3.14 The Klambu Kanan system will supply water to a net irrigable area of19,000 ha in a gross area of 24,000 ha. Works include the construction of anew barrage at Klambu; 192 km of primary and econdary irrigation canals;111 km of new and improved secondary drains,9 including some "river training'works; and 107 km of inspection roads for operation and maintenance along theirrigation and drainage canals. The irrigation area will be divided into 321tertiary units with an average size of 59 ha net irrigable area. Additionalservice roads (90 km) will also be constructed.

91 88 km of primary drains will be consLc.^ted under Irrigation XIV(Ln. 1811-IND).

3.15 improvements to Existing Irrigation Systems. For the Sedadiirrigation area (13,910 ha), water will be supplied from the Sedadi weir whichwill be upgraded. Capacity of the main Si canal (41 km) (see Map le529) willbe increased at the upstream end from 12 to 21 cms to supply the 13,910 ha.The supply from the Tuntang River via the Tl canal will be diverted to supplythe Tuntang irrigation systems. One secondary canaL will be expanded. cheS2/S16 (10 km) canaL, and most secondary canals (58 km) will have minoradjustments (Table 3.3). Tertiary systems have been completed, but minoradjustments in the structures will be made to accommodate changes in thesecondary canal. Main (58 km) and secondary (66 km) drains will berehabilitation. Additional inspection roads (20.5 km iong) will beconstructed (see Annex 3 for details).

3.16 Klambu Kiri will have its main and tertiary canal system upgradedwith new tertiaries in 50Z of the Lower area (Wedung). A new (twin) maincanal (16 km) parailel to the Si canaL will be constructed from the Klambubarrage (see Map 18529) to provide water for the entire 20,330 ha. The onlyother supply will be the Sedadi-Pelayaran (7.9 km) secondary canal connectingthe main canal to che Pelayaran canal. Adjustments will be made to a further24 km of main canal to increase its capacity. Major adjustments will be madeon the secondary canals (128 km) in the Wedung area and modevate adjustmentswill be made on canals (41 km) in the Pelayaran area. The main systemstructures in Wedung and the Pelayaran area require major adjustments orreplacement (see Table 3.3). Main drains (97 km) are being upgraded underLn. 1811-IND while secondary drains (164.5 km) will be constructed under thisproject.

Status of Project Preparation

3.26 The designs and all major investigations for the main dam and power-house have been completed. Bidding documents have been reviewed by the Bankand found satisfactory. The schedule for tendering the main dam andpowerhouse for international comperitive bidding CICB) is: invitations wereissued on August 6, 1984 for 19 Drequalified contractors; bids were opened onDecember 6, 1984; DGWRD' s recommendation for cender award -was on February 28,1985 and the award will be in .av 1985. A condition of loan effectivenesswill be the signing oi the concract -sr dam and powerhouse construction.Designs for che diversion tunnel. base camp and hauL road have been reviewedby the Bank. Their construction is under way by local contractors and will becompleted prior zo the contract award for the main dam. These initial workshave been fully funded by GOI, and demonstrate GOI's incenc to oroceed withthe project.

3.27 Geotecnnical investigation and detailed surveys and designs for theKlambu barrage and all other major irrigation structures and canals have beencompleted. Detailed designs for secondary and tertiary systems will becompleted in stages by the end of 1986. The existing designs andinvestigations for these systems are to a sufficient standard for computingfirm cost estimates. Detailed tender documents and specifications would beavailable in mid-1986 for calling of tenders for the irrigation works (seeAnnex 4). Detailed specification and designs for the Flood Monitoring Systemhave been completed, are being reviewed by the Bank, and will be tendered inJuly 1985.

3.28 Land acquisition for the area (340 ha) around the dam site has beencompleted and about 300 families have transmigrated. The GOI has firm plansto acquire most of the settled land in the proposed reservoir area by1987/88. The Governor of Central Java has set up coordinating committees for(a) land acquisition and (b) resettlement.

Dam Safety

3.29 A panel of three international dam experts have been recruited, havereviewed design and tender documents for the dam, and have found the designsand investigations satisfactory. This panel will continue to review anydesign modifications and safety arrangements needed during construction uptill 1990. GOI will keep the Bank continually informed of the panel'sfindings (para. 4.02). Dam safety inspections will be performed by ;HEinspection teams on a routine basis (twice a year or more frequently) afterthe dam is completed. An assurance was obtained during negotiations that byDecember 31, 1989 IHE wilL submit for the Bank's review a plan for theproposed dam inspection arrangements, and will carry out such plan asacceptable to the Bank.

Implementation Schedule

3.30 The implementation schedule for the project is presented inAnnex 4. The dam will be compLeted in four years (by early 1989) while theirrigation system construction will be completed in six years (by mid-1991). The implementation targecs are modest in terms of what has beenachieved in dam and irrigation construction in Indonesia.

Cost Estimates

3.31 Total project costs are estimated at US$283.1 million (excludingtaxes of US$17.2 million) of which US$122.7 million (or 44%) will be foreignexchange. Project costs are expressed in January 1985 prices and at anexchange rate conversion of Rp 1,100 = US$1.00. Unit rates for the irrigationsystem are based on similar irrigation works in the project area, and for thedam on the lowest bid prices of the ICB tenders which were submitted inDecember 1984. A 19 i allowance for physical contingencies has beenincluded for the dam, 15Z for the irrigation works, and 5% on consultantservices and special equipment. Expected price increases total about 21Z ofthe base cost and were estimated on the basis of the following inflationrates: for local costs 8% in 1985-90, 5% thereafter; and on foreign costs, 5%in 1985, 7.5Z in 1986, 8% in 1987-90, 5Z thereafter. Details of project costsare given in Annex 1, Table 1 and are sumnarized in Table 3.4.

Financing

3.32 The proposed loan of US$156 million (see Annex 1, Table 6) willfinance about 60Z of total project costs excluding taxes (US$17.2 million),reserve procurement of vehicles (US$2.1 million) and equipment for the powercomponent (US$21.3 million) wnich will be financed by export credits. Theloan will finance the remaining Eoreign exchange costs (US$104.1 million) ofthe project and US$51.9 million of local costs. GOt wiLl finance the balanceof the costs of US$105.8 million (Table 3.5) and is arranging for financing ofthe power component by export credits to be available by December 1985. Theproposed cost sharing arrangements are justified since (a) the projectbenefits almost entireiy low-income farmers or iandless agricultural laborers(paras. 6.05-6.06), and (b) without external assistance COI would have to slowdown implementation to che detriment of economic viabilicy.

Procurement

3.33 Civil Works. The dam and associated works (US$43.7 million) will beconstructed through a single contract procured using international competitivebidding (ICB) procedures. The Klambu barrage, Klambu Kanan main canal andSidorejo weir (US$35.0 million) will be contracted through ICB. A series ofabout 56 smaller contracts (US$77.0 million) will construct a series ofsmaller and widely dispersed irrigation works which are unlikely to attractforeign contractors. For these, local competitive bidding (LCB) proceduresopen to foreign contractors and acceptable to the Bank will be used. Table3.6 summarizes procurement arrangements under the project.

3.34 Equipment. Procurement of major equipment for operation and maince-nance (US$1.8 million). and for specialized telemetry and computers for floodwarning and water monitoring (US$9.4 milLion) will be procured through ICB.Other small Laboratory, office, hydrometeorologic and minor O&M equipment(US$0.9 million) will be procured locally in small Lots through GOIprocurement procedures acceptabLe to the Bank.

Review of Procurement

3.35 All civil works contracts are reviewed by the Procurement ControlUnit (DCWRD) and for contracts Larger than US$500,000. clearance must aLso beobtained from the Ministry of Public Works procurement unit and the SEKNEG -the State Secretariat. The Bank reviews contract evaluation and award throughits RSI (Resident Staff. Indonesia) which works closeLy with these agencies onprocurement matters. The 3ank has reviewed the contract cocuments for the dam(US$43.7 million) and found them sacis.actory. The Bank will review prior totendering and award about 24 additional contracts (USS79.0 million) eachvalued at over USS1.5 miLlion. About 32 other contracts (US$33 million), eachvalued at less than USS1.5 million, will be reviewed by the ProcurementControl Unit, and subsequently by the Bank, on a sample basis after award.The two ICB contracts for equipment (totaLling US$11.2 million) will bereviewed by the Bank prior to tendering. Equipment procured in smalL lots notexceeding US$0.2 million in value will be reviewed after award on a samplebasis.

Disbursements

3.36 Loan funds will be disbursed against:

Disbursements will be made against contracts, except for training costs andcivil works costs for contracts Less than USS1.5 million -hich wiLl bedisbursed against statements of expenditure (Annex 10)._1I rhe proposedallocation of loan proceeds is presented in Annex 1, Table o. rhe disburse-ment profile (Annex 1, Table 7) is projected over a six-year period fromSeptember 1985 to June 1991. The profile follows fairly closelv tneIndonesian and Bankwide disbursement profiles for similar works. Loan Closingis expected by December 31, 1991.

Accounts, Audits and ReDorting

3.37 Detailed separate accounts and records are kept by DGWRD and PLN foreach budget item by project and budget year. Carrv-overs of unspent funds(SIAP) are permitted for two vears. 3ecause SIAPs are permitted, cash booksand accounts are not closed until the budeet for the Line item has been fullyspent. Project accounts are subiecc-to two audits: (a) by the InspectorGeneral of the Ministry of PubLic Works (MPW), and (b) by the Financial andDevelopment Supervisory Board (BPKP). The work of both auditors has beenfound to be generally satisfactory on Bank-assisted irrigation projects.Assurances were obtained at negotiations that adequate and separate accountswill be maintained: all contracts, orders and receipts will be kept for atluast one year after loan closing; and independent audits by BPKP of eachyear's accounts will be submitted to the Bank within nine months of the cLoseof each GOI fiscal year. Assurances were also obtained that DGWRD wouldprepare a Project Completion Report which will be submitted no later than sixmonths after loan closing.

Environmental Impact

3.38 Resettlement. Senior environmental specialists and managers fromthe Institute of Ecology, Padjadjaran University, supervised by internationalconsultants, have been involved since 1981 in identifyir7 the detailed reset-tlement needs of the project, and preparing an environmental impactassessment.

3.39 In 1982, the Government of Central Java set up a coordinationcommittee at the provincial and district levels to coord:nate the transmigra-tion and resettlement of the popuLation to be inundated by the reservoir. Thecoordination committee is responsible to: (a) carry out ̀ .tailed surveys ofthe area through the provincial Agraria for purposes of compensation of landand facilities; (b) supervise land transactions; and (c) establish resettle-ment and transmigration implementation teams to coordinate with the peopLeaffected.

11/ A revolving fund wilL not be used in the proposed project because ofexisting prefinancing arrangements with GOI for the irrigation sector.The introduction of such a fund for future projects is being discussedwith GOI.

3.40 Some 5,390 families (23.380 oeopie) in 2C vilLages wiil be relo-cated. About 12,200 of these people are in che iabor force and 50 are far-mers, 27% are Laborers, 18Z are unempioyed, and 5% have other employmenc.Sample surveys of villages show chat 55% of the people nave incomes below theminimum poverty level. Popuiacion densities vary from 860 to 1,060 people/sakm. In the most recent survey in 1983, 75Z of the famiLies wanted to trans-migrate. Resettlement within the catcnmenc is discouraged because of _ne veryhigh population density and the low productivity of the upland areas. ReDre-sentacives of the affected villages have visited the proposed transmigracionsites in Irian iaya and Bengkulu in Sumatra, and were sacisfied wich Ehesites. Some 300 families have already cransmigraced. The Proiect Office. incooperation with the Central Java Provincial Coordinating Committee. has ore-pared a resettlement plan, compensation payments and schedules acceDcable tothe Bank (see Table 3.7). Assurances were obtained during negotiations thatGOI will provide adequate and timely budgecary resources for compensation pav-ments and will provide the Bank with annual reports on the resectlement,compensation, and welfare of people affected by the reservoir constructioncommencing December 31, 1985.

3.41 Judging from the experience gained on similar dam sites in CentralJava, the present number (25%) of all families who preferred relocation inJava will probably decrease to 1OZ as transmigration accelerates. The remain-ing 10% have land outside the catchment, or may choose to live with rela-tives. For these people, the Kabupatan Coordinating Development Comitteewill give them preference for vocational training, work in local rural worksprograms, and in the project's civil works construction program (see Annex 8).

- 34 -

3.42 Other environmental aspects of the project include:

(a) The dam will substantially reduce flooding in the upper Serang Riverat the junction of the Serang and Lusi. The upper Serang with themodified flows will peak in the dry season. The present floodingdownstream of the basin will also be substantially reduced;

(b) The Serang and Lusi watersheds are the subject of a recentlyapproved Upland Agriculture and Conservation Project (Ln. 2474-IND)supported by the USAID and the Bank. During negotiations assuranceswere obtained that the measures taken for catchment procection underthis loan will focus on soil and water conservation. in addition,studies will be undertaken by the Directorate General of LandRehabilitation and Reforestation (DGLRR) for improved soil and waterconservation for the proposed Jatigede Dam catchment on che Ci.anukRiver;

(c) Public health will be improved due to the increased quantity andquality of water available year-round for drinking. Assurances -wereobtained during negotiations that a plan for a continuous canalwater quality monitoring system will be established by the IHE inconsultation with the Provincial Health Services by December 31,1988 and the system will be in place by June 30, 1991;

Cd) There are no archaeological sites or artifacts of any significancein the area to be submerged. Construction of the project is alsonot expected to adversely affect fauna in the valley; and

Ce) Public health authorities, with the cooperation of the ProjectOffice, will intensify malaria control efforts as the irrigation andcropping patterns intensify, since some of the vectors are presentand there is some incidence of malaria in the project area.Assurances were obtained at negotiations on appropriate measures formalaria control in the project area.

IV. ORGANIZATION AND MANAGEMENT

National Level Organization and Management

4.01 DGWRD in the Ministry of PubLic Works will be the principalexecuting agency for the project responsible for all design and supervisoryconsulting services and all civil works for the dam, substructure of thepowerhouse, major diversion, irrigation and drainage works. PLN, under theMinistry of Mines and Energy, will be responsible for the construction of thesuperstructure of the powerhouse, electrical and mechanical facilities,equipment installation for the powerhouse, and construction of thetransmission line.

4.02 DGWRD will carry out its responsibilities through its Directorate ofIrrigation II (DOI-II) (see Chart 26628). A panel of dam experts, established

- 35 -

to review designs, will continue to review design modifications, safety andeconomy throughout conscruc:ion. and report to DOI-II (para. 3.29).Assurances were obtained ac aegotiations that the dam panel's comments priorto and during construction regarding safety and economy in construction shailbe properLy taken into accounc and that their periodic reports shall be madeavailable to che Bank not :.acer than one month afrer each visit. IHE willorganize the inspection teams on a routine basis (three times a year) for aperiod of five years to perform dam safety inspections. IHE in consultationwith the Directorate oi Rizers (DOR), DOI-I and DOI-II will implement thetraining component of the project. IHE with DOI-II's Project Office willestablish the Flood Warning and Water Monitoring Center.

4.03 PLN will implement the power component (see Chart 26718) through itsDirectorate of Construction, which will manage the consultancs for the powerstation, and the procurement and instalLation of the electrical and mechanicaL-equipment according to the schedule shown in Annex 4. An assurance to thiseffect was obtained during negotiations.

Field Level Organization and Management

4.04 At the field level. DOI-II's Jratunseluna General Project Officewhich was established in 1976 in Semarang, will be responsible for theproject. To manage day-to-day supervision of construction this office has twoProject Offices for the Kedung Ombo Dam and Irrigation (Chart 26629). TheKedung Ombo Dam Project Office is located in the town of Purwodadi, with asite office at the dam location. The Government wishes to continue theservices of consultants, SMEC, who will be responsible for supervisingconstruction of the dam at the site (Chart 26630). The Irrigation ProjectOffice has been established at the town of Godong, and will be responsible forsupervision of construction of all irrigation works, assisted by local andsome foreign consultants (Chart 26631). The present and future staff needsare shown in Table 4.1. An assurance was obtained during negotiations thatall staffing requirements will be met by September 30, 1985 for the DamProject Office and by January 31, 1986 for the Irrigation Project Office, andthat vehicles required for implementation will be provided on a timely basis.

/b Shortfalls in future staff will be met by reassignments within theJratunseluna Of'ice.

/c Professional staff are mainly engineers while nonprofessionals aretechnicians, draftsmans, surveyors, etc.

4.05 For the power component, the Central Java Hydropower and Transmis-sion Project Offices of PLN in Semarang will be responsible for day-to-daysupervision of the project. The Hydropower Project Office will set up aProject Office at the dam site to supervise construction of the powerhouse andthe installation of the generator sets. The transmission line contractor willbe supervised by the Transmission Office of Central Java in Semarang.

4.06 IHE's Division of Hydrology will establish by June 1986 a SubprojectOffice within the Jratunseluna General Project Office to implement the FloodWarning and Water Monitoring System. This Subproject Office will supervisethe contractors responsible for the installation of telemetry, the water leveLmonitoring stations, computers, and software in the Kudus Water ControlCenter, and will work closely with the Provincial Public Works Office inSemarang, the new Regional (wilayah) office of Pati, and with the ProjectOffices for the Dam and Irrigation. The Jratunseluna General Project Officewill also be responsible to ensure that the Water Control Center at Kudus willbe adequately staffed and sufficiently trained by the contractor to manage thewater allocation and flood warning operations (para. 4.09).

- 37 -

4.07 IHE through its Training Divison will be responsible for all train-ing components in the project. IHE will coordinate with the relevant dir-ectorates in DGWRD to organize training, including the recruitment of expertsto teach the dam construction, dam inspection and reservoir operationscourses. The dam construction, dam safety and reservoir operations courseswill be scheduled for 1986 and 1987. Participants in these courses will be asfollows: three each from the iratunseluna Office and the three ProjectOffices; two each from DOI-I, DOI-II and DOR; and three from tHE. Coursematerial will follow that used by the U.S. Bureau of Reclamation.

Project Coordination

4.08 Since agencies from three Ministries at the national, provincial andkabupaten levels are involved in the project, effective coordination of proj-ect activities will be needed at all stages and levels. The followingarrangements have been established and are shown on Chart 26718. DGWRD as theprincipal executing agency wilL coordinate with PLN's central office and theDirectorate General of Civil Government and Autonomy (DGCGA) under theMinistry of Home Affairs at the national level. At the field level theJratunseluna General Project Office will coordinate with the newly establishedKedung Ombo Development Coordinating Team under the Office of the Governor ofCentral Java. The Project Offices for the dam and irrigation will coordinatewith the subteams of the Development Coordinating Teams at the kabupaten levelfor all land and water control and agricultural aspects of the project. TheJratunseluna General Project Office will also coordinate with the Central JavaHydropower and Transmission Project Units of PLN for all aspects of the powercomponent.

Operation and Maintenance (O&M)

4.09 Organization for O&M. At present the four project irrigation areasfall in three irrigation regional (wilayah) offices (i.e., Wilayah Pati,Semarang and Surakarta) and four irrigation sectional (seksi) offices. Duringnegotiations assurances were obtained that the Provincial Irrigation Servicein Central Java will reorganize its irrigation offices and operations by April1, 1989 (two years before project completion) as follows:

(a) reconfigure the wilayah boundaries so as to follow watershedboundaries of catchments, and, for the project irrigation, all areaswill fall under one wilayah office (called the Pati Wilayah) withits headquarters at Kudus (Map 18531);

(b) establish a new seksi office for the operation of the dam;

(c) establish the four project irrigation areas under three seksi(Serang Bawah, Serang Atas and Pati). The Serang Bawah Seksi willbe responsible for the maintenance of all waterways in the lowerSerang;

- 38 -

(d) for the operation of the project, a Water Allocation Committee willbe set up composed of the four seksi representatives (Serang Bawah,Serang Atas, Pati and Kedung Ombo). The Committee will meet atleast once a week. or more frequently as needed, at Kudus todetermine the weekly operating rules for water releases from thedam, and proposed allocations for the various systems; and

(e) the Water Control Center at Kudus with all the necessary telemetric,hydrologic and hydraulic information will advise the WaterAllocation Committee (WAC) on the possible options for waterallocation for the various systems and the releases from the dam.Water allocation will be decided by the WAC. The Water ControlCenter will have adequately trained staff, who will be in place byApril 1, 1989, two years prior to project completion.

4.10 initial Operations and Maintenance (O&M). During construction, theIrrigation Project Office will be responsible for O&M of the new irrigationsystems (Klambu Kanan and Sidorejo). O&M of the existing Sedadi and KlambuKiri systems will remain the responsibiLity of the Central Java ProvincialIrrigation Services under the existing Serang Atas and Serang Bawah irrigationsection offices. O&M of the tertiaries and quaternaries will be theresponsibility of existing water user organizations (see Map 18534) and newones to be organized in newLy developed areas. After completion of construc-tion, the Project Offices, together with the new Water Control Center atKudus, will be responsible for O&M of the dam, the Klambu barrage, the newtwin canal leading to Klambu Kiri, and the Klambu Kanan and Sidorejo systemsfor a period of not less than two years. On completion of the power station,PLN will set up its own site office close to the dam site which will beresponsible for O&M of the power station. This office will be under PLN'sRegion XIII Office located at Semarang. PLN's site office will coordinatewith the Project Office during the initial period of operation.

4.11 PLN will enter into an agreement with DGWRD and the ProvincialCovernment by July 31, 1989, prior to the commissioning of the power station,providing, among other things, operational rules and criteria for utilizationof reservoir water for irrigation and power purposes. In the event that anysubstantial changes in the cropping pattern and/or irrigation releases fromthe dam are proposed which could affect power generation, DGWRD will consultPLN before such changes are adopted. The Government will inform the Bank ofany such proposed changes in sufficient time to give an opportunity tocomment. A share (50Z) of the cost of operation and maintenance of the intakeof the dam and irrigation/power tunnel will be borne by PLN. PLN will bearthe cost of O&M of the powerhouse. Assurances on the above were obtained atnegotiations.

4.12 Sustained O&M. Two years after completion of construction,responsibility for O&M of the dam, Klambu barrage, main linking canals, andmain system irrigation and drainage for the Klambu Kanan and Sidorejo sub-systems will be turned over to the Provincial Irrigation Services of CentralJava (Kedung Ombo, Serang Atas and Pati irrigation section offices, respect-ively). PLN's regional office (Region XIII) will continue to undertake O&M ofthe power station. Day-to-day operation of the entire irrigation system and

- 39 -

dam will be controLled by the newLy established Water Control Center's WaterAllocation Committee at Kudus. PLN's new office at the dam site will be res-ponsible for the operation of the power station. In addition, the threeirrigation seksi will be responsible for day-to-day operations of the threeirrigation subsystems up to the tertiary level in the service area. The waterusers associations will continue to be responsible for OL& of the tertiary andquaternary canals (see Map 18534). New associations will be formed in thenewly irrigated areas. Within each irrigation seksi the overall waterallocation will be determined by the existing irrigation advisory committees(Panitia Pengairan) at the village levels.

4.13 O&M of the canal inspection roads is carried out in conjunction withthe O&U for irrigation. The O&M of the kecamatan and village roads will beperformed by the local kabupaten public works offices.

4.14 O&M staffing needs for the various irrigation section offices areindicated in Annex 9, Table 1. O&M cost allocations which should adequatelycater for the dam, irrigation and downriver works are US$0.50 million, US$0.89million, and US$0.34 million, respectiveLy, and are based on existing irriga-tion O&M costs for the Serang Bawah and Atas Section offices for irrigation(see Annex 9, Tables 2 and 3) and on future needs. The average costs per hafor dam, irrigation and downriver works are US$8.40/hatyr, US$15.00/ha/y-r andUS$5.8O0haIyr, respectively (see Annex 9. Table 4). An assurance was obtainedduring negotiations that adequate (as indicated in Annex 9, Table 4) andtimely funding and staffing will be provided for 0& (para. 6.09).

4.15 Monitoring and Evaluation (MXE). M&E of the project during andafter implementation are important to ensure that project objectives aremet. The N&E information on water management will be obtained from telemetricdata on every 1,000 ha, available through the water control center at Kudus,and from information gathered by irrigation section and subsection offices andby village water masters. The M&E information on agricultural production,input supply, etc. will be gathered by agricultural extension workers (PPLs,PPMs. etc.) and by village contract farmers and village chiefs. The evalua-tion of the general performance of the irrigation systems would be performedat three levels (the village, kabupaten, and regional (wilayah)) throughgovernment-established committees known as "Penitia Pengairan" using theabove information. The committees have representatives from local governmentirrigation, agriculture and district sectional offices. The village, districtand regional level committees meet at bimonthly and monthly frequencies. Inthe existing irrigation areas in Sedadi and Klambu Kiri, these committees areoperational and functioning satisfactorily. For the new irrigation areas, GOIlegislation requires that committees will be set up prior to the completion ofthe project.

V. AGRICULTURAL SERVICES AND PRODUCTION

Agricultural Services

5.01 Agricultural support services in the project area are being streng-thened by several Bank-assisted projects and government programs. Ongoingprojects include the Second National Agricultural Extension Project (NAEP II,Cr. 996-IND) and the Seeds II Project (Ln. 2066-IND). The main source ofinputs for rice production in the four project area districts is the Govern-ment's INMAS program. The INMAS program provides Earmers with subsidized HYVseed, fertilizer and agrochemicals and technical advisory services by fieldextension staff. Under the program, farmers pay cash for the productioninputs which are supplied through the local outlets. Since 1979 a groupapproach called the INSUS program has also been expanding in the projectarea. The objective of the INSUS program is to encourage farmer groups in anarea of not less than 10 ha, to organize land preparation and planting withinspecific time limits, to organize water management, to use HYVs andfertilizer, etc. In 1984/85, the INSUS program covered almost 80% of thetotal planted area in the project districts.

5.02 Crop production intensification methods with use of HYVs andfertilizer inputs are well established in the project area, and during each ofthe past five years data on fertilizer use and farm surveys indicate thatimproved technology has been adopted on more than 90% of the area planted withrice. Seeds, fertilizer and pesticides are readily available in the projectarea, and no supply constraint is expected under the project. Extensionservices under the Directorate General of Food Crops Agriculture are alsoadequate.

5.03 Crop Marketing. About 90% of the marketable surplus of rice in theproject area is sold by farmers as padi to private traders or millers. Thenumerous private traders operating in villages in the area provide competitionand offer services such as farm collection and drying of produce. About 370private rice mills and 26 government mills serve the project area subdis-tricts, and almost 200 rice mills are located within the project area bounda-ries. Milling capacity is expected to be adequate for incremental productionunder the project. Marketing of palawija crops is handled almost entirely byprivate traders, and well-established marketing channels exist, especially forsoybean and mungbean. In order to cater for increased marketing needs as aresult of the project, market and village access roads will be constructedunder Government's INPRES program. Village Class V roads will be upgraded toClass IV roads in ledadi/Klambu Kiri (57 km); Klambu Kanan (10 km); andSidorejo (11 km). 1 New farm-to-market roads will be constructed inSedadi/Klambu Kiri (42.5 km); Klambu Kanan (73 km); and Sidorejo (335 km).Assurances on the access road construction program were obtained atnegotiations.

12/ Class V and IV roads are, respectively, 3.0 and 3.5 meter wide, sealedall-weather roads.

- 41 -

Changes in Crop Production under the Project

5.04 The project will increase agricultural production on about 59,340 hain the Serang River Basin. The major crops grown are rice, maize, soybeans,mungbeans and sorghum. Minor crops such as groundnuts, sugar and cassava havebeen ex.cluded from the analysis. The main benefits will result from theprovision of a reliable and timeLy supply of adequate irrigation water and themitigation of flood damage, allowing production of two crops of irrigated ricein the project area followed by secondary (palawija) crop production on aboutone third of the area.

5.05 Cropped Areas and YieLds. Overall cropping intensity for rice willincrease from a current (weighted) average of about 105% in the four areas to200Z at full deveLopment. Cropping intensities for the total cropped area(rice plus palawija) will increase from a present weighted average of about175% to 230% with the project at full development (Table 5.1).

over 200,000 ha (Irrigation V, Cr. 512).

5.06 Based on water availability and the existing technology available tofarmers, a cropping intensity of 230% with the project is reasonable. Thnischange results in an incremental area of 83,430 ha growing rice (wet and dryseason), an 236% increase over the present. The area planted with palawijacrops will decline by 20,200 ha or 52% (Table 5.2). The only net increase incommandable area is in Klambu Kanan where a 15% increase occurs due to theimpact of drainage activities under the Irrigation XIV Project (Ln. 1811-IND).

5.07 Paddy yields are expected to improve by about 25% to 55% over thefour areas and palawija yields by about 8-35% with the project (Table 5.3).The expected future yield estimates are shown in Annex 2, Table 3. Theprojected yield estimates take into account both the impact of the IrrigaticnXIV Project (due to be completed at end-1986) and the negative impact of anycontinuing flood problems in the area.

5.08 Production. Paddy production in the area will rise substantiallyfrom about 0.20 million tons per year in 1984 to about 0.54 million tons peryear with both the proposed project and Irrigation XIV. Incremental annualrice production at full development (1993) will be about 0.34 million tons,but secondary crop production will decline by about 12,780 tons from thecurrent level of output. Eliminating the impact of the Irrigation XIVProject, incremental rice production due solely to the proposed project willbe about 0.29 million tons per year at full development, but palawija produc-tion may decline by 35,480 tons per year (Table 5.4). These increases inagricultural production will generate about US$41 million in annualincremental agricultural benefits (Annex 2, Table 11).

5.09 Build-up of Production. In accordance with the implementation sche-dule (Annex 4), the phasing of agricultural build-up is presented in Annex 2,Tables 12 and 13. Full agricultural benefits are assumed to be achieved afterone year in Sedadi and over three years (50Z in year one, and 75X in year two)in the remaining areas after each part of the irrigation system iscompleted. Full agricultural deveLopment of the total project area is reachedin 1993, four years after the completion of the dam.

VI. MARKET PROSPECTS, PRICES, FARM INCOMES AND PROJECT CHARGES

Market Prospects

6.01 Central Java is only now approaching self-sufficiency in rice.Although the world price of rice has fallen sharply (para. 6.02) almosteliminating the subsidy received by farmers, production will be encouraged toguarantee the stability of Central Java's rice self-sufficiency and providesurplus rice for other regions. Thus marketing prospects for paddy shouldremain favorable, and in the event of lower prices, farmers are expected toincrease palawija crop production.

Prices

6.02 Economic and financial prices for major agricultural inputs andoutputs are presented in Annex 2. Table 1. Estimated farm inputs and outputsare valued in constant January 1985 prices in farm budgets and economicanalyses. Economic prices for rice, maize, soybean, mungbean, sorghum andfertilizers are based on the world market price forecasts produced by theBank's Commodities and Export Projections Division adjusted fortransportation, processing and handling costs to che farmgate. Financialprices for all commodities and economic prices for inputs not tradedinternationally have been updated from actual farmgate orices. In the past,COI maintained low consumer food prices by subsidizing the sale of importedrice and holding domestic floor prices Low. To offset an adverse impact onproducers, GOI subsidized fertilizer and pesticide prices. in recent years inorder to encourage production, paddy floor prices have been raised consider-ably. In addition, recent declines in the world rice prices have contributedto almost eliminating the rice subsidy. For project analysis, financialprices of rice have been assumed to converge with economic prices. To dis-courage the excessive use of fertilizers and reduce subsidy elements, COI, inearly 1983, raised the price of urea and triple superphosphate (TSP) from Rp70/kg (unchanged since 1977) to Rp 90/kg. However, the domestic price isstill below the border price and is expected to remain low in the 1990s.

Farm Incomes

6.03 Three typical farm sizes (0.2 ha, 0.4 ha, 0.6 ha) have been selectedfor farm income analysis in Sidorejo and Klambu Kanan and three (0.1 ha, 0.4ha and 0.6 ha) in Sedadi and Klambu Kiri. In the analysis it is assumed thatthe farm family, consisting of 4.6 persons, provides 1.7 man-days of labor for22.5 days per month. In the months of peak labor requirement such as plantingor harvesting, when most of the month's activity must be completed in aboutten days, it is assumed that labor is hired. This amounts to about 20% of thetotal labor requirements at full development. It is aLso assumed that allanimal labor will be hired. In addition, there are a few off-farm employmentopportunities, the majority being seasonal tobacco or factory work in centerssuch as Semarang, Demak or Kudus. These employ predominantly women or youngadults at an average wage of about Rp 600/day. These representative farmmodels, shown in Annex 2, Tables 15a-d and 16 a-d are summarized in Table 6.1.

year, similar to the level for all tndonesia of about US$103.1.131 However,consumption estimates indicate chat since i980, the position of Central Javacompared to the ryX5 of Indonesia has worsened. Bank estimates of the inci-dence of povercy _ reveal that rural areas in Central Java have a greaterconcentration of poverty (62%) than all Indonesia (43% of the national popula-tion are estimated to have incomes below the absolute poverty Line). It isexpected that the majority of notentiaL beneficiaries would remain at incomesbelow the absolute poverty level without the project. On the smallest farms(0.1 in the Sedadi and Klambu Kiri and 0.2 ha in Sidorejo and Klambu Kanan),incomes will remain below the absolute poverty level with the project.Nevertheless. farmers wilL stii be substantially better off, and incrementalincomes are espected to rise between about 47% and 145%, with a weightedaverage increase of 98Z over the whole project area.

6.06 Encome Distribucion. The project area inciudes: about 87,000 farmoperator households; about 11,000 farm laborer househoLds which are separatefrom owner-operators and about 22,000 living within owner-operator households;and about 23,000 nonfarm households. An area of about 2,000 ha of drainedswamp land in the Klambu Kanan area will be redistributed to landless agricul-tural labor in the project area. Comparing tenant income with owner-operatorincome, the income of former cenants will increase by about 20-25% in KlambuKanan, 15-20X in Sidorejo and about 15% in Sedadi and Klambu Kiri. The incomeof landless laborers (only 101 in project areas) is estimated to increase by5-10% due to increased farm employment.

Project Charges

6.07 Indonesian farmers pay land taxes (IPEDA) and make contributions tovillage watermasters who are responsible for tertiary network operation andmaintenance. Land is classified according to a number of physical criteriaand IPEDA is charged at a fixed tariff which varies by land class and totalland holding. The revenue is collected by village heads and turned over tothe local (Kabupaten) and provincial administration for financing local devel-opment. Projected increases in land classes due to irrigation and otherimprovements and consequent IPEDA increases in each area are detailed in Annex2, Table 17a. Assurances were obtained during negotiations that GOI will(a) reclassify for IPEDA purposes all land benefitting from project works,section by section within one year of completion of works, and (b) reassessand collect IPEDA taxes from all project beneficiaries in accordance with anagreed implementation schedule. At full development, IPEDA in the projectarea will range from about US$13/ha/year to about US$22/ha/year. In-kindcontributions for water in the project area are 25 kg of paddy per crop. Atfull development, water contributions are expected to be about US$8/ha.

13/ These estimates are drawn from the 1980 Indonesia Household ExpenditureSurvey, released in 1983. The 1980 rupiah estimate is inflated by aprice index for nine basic items of 56% from 1980 to end 1983 andconverted to US$ at the prevailing exchange rate of.Rp 1,000 = US$1.

Farmers will also contribute about 20 man-days of their labor, equivalent toabout Rp 26,GOO/farmIyear. to operate and maintain the village level irriga-tion system.

6.08 Cost and Rent Recovers. Present and estimated future levels ofIPEDA, water service concriDuEions and O&M labor contributions are summarizedin Annex 2, Table 18a. At -ull development, incremental IPEDA and othercharges wiLl more than offset incremental O&M outlays for main and secondarynetworks. It is oer-haps miore meaningful to observe the cost and rent recoveryindices jhich estimate cost and rent recovery due to the stream of chargesover the project's .ife. The cost recovery index. ranging becween about 6%and 26% (averaging i6Z), is the ratio of the present vaLue of incrementaldirect revenue (IPEDA and other contributions) to the presmgg value ofincremental financial project costs in January i°85 terms.-' The rentrecovery index, ranging from about 6% to almost 23%. is che racio of thepresent vaiue of incremental direct revenue (IPEDA and other contributions) tothe present zalue of incremental net financial project rent. These rates arein line with those in similar recent projects in 7ndonesia. The recoveryrates are considered reasonable due to the low incomes of Droject bene-ficiaries (para. 6.05). O&M cost recovery ranges *rom about 86Z in Sedadi(0.6 ha farms) to about 355% in Sidorejo for 0.2 ha (Annex 2, Table 18c).Incremental streams of O&M contributions over the oroject's life and theresultant cost and rent recoverv index are shown in Annex 2, Table 18c.

6.09 O&M Funding. Support for O&M on the main irrigation system from thecentral government has been increasing steadily over the past few years. Inaddition, for Bank-assisted projects, part of the capital development budget(the DIP) has recently (in the 1983/84 budget) been directed to support O&Mactivity which has reduced the shortfalls in O&M budgets from 40% to 20%.Shortfalls in 0&M can have consequences on the agricultural benefits achievedover the project's life (para. 7.12). Additional funding sources for OE& havebeen agreed in principal with GOI by use of revenues collected from IPEDA.Assurances were obtained at negotiations that sufficient (see Annex 9, Table4) and timely funds will be allocated to O&M, and that GOI will increase 1PEDArates for reclassified land (para. 6.07), and furnish to the Bank by December31, 1988 a plan to allocate the incremental IPEDA thus collected to O&M ofproject works following construction.

VII. 3ENEFITS, ECONOMIC JUSTIFICATION AND RISKS

General

7.01 The project complements the previous Bank,gupport in water resourcedevelopment in the project area. EarLier projects concentrated onrehabilitating the existing irrigation system, mitigating flood problemsthrough constructing main and some secondary drainage, and undertakingextensive tertiary development in the Sedadi and Klambu Kiri areas. Theproposed Kedung Ombo Multipurpose Dam and irrigation Project will enhancewater avaiLability through water storage in a dam, expansion of the irrigationarea to the Klambu Kanan and Sidorejo areas. and substantial improvement ofexisting irrigation svstems in the Sedadi and KLambu Kiri areas. The projectwill also assist ongoing flood control activities through reservoir operationand the continuation of drainage works. Yainly secondary power (a total of 74GWh per vear) will be generated resulting from the operation of thereservoir. Municipal and industrial water will also be supplied through theirrigation canals throughout the year. The proposed proiect is high on COI'sdevelopment priorities in view of its large agricultural and flood controlbenefits, in an area mostly without dry season water, yet subject to floodingin the wet season.

Benefits

7.02 Agricultural Benefits. Approximately 87,000 farm families willdirectly benefit from the project and their incomes will increase (para. 6.05)due to increased agricultural production valued at US$41 million (See Annex 2,Table 11). An additional 33,000 farm laborer households, 20,000 cf which arecontained within farm operator households, will also benefit. There will alsobe indirect beneficiaries due to the improved access and communications in thearea from the new feeder roads and access tracks to be constructed or upgraded(para. 5.03). The full costs of these roads have been charged to the project,although no road user benefits have been quantified.

7.03 Power Benefits. Power generation will be incidental to theoperation of the reservoir and will be secondary to the main objective ofproviding irrigation. On average, 74 GWh of electrical energy will begenerated per year. The main benefit from the energy generated will be thesaving of cost of fuel from oil, diesel or coal stations. PLN's simulationsindicate that for the proposed future network of generating stations startingfrom 1989 onward, the Kedung Ombo power station will initially accrue savingon fuel from oil fired steam stations (1989 to 1994), while in the latteryears (1995-2020), it will save fuel from the coal fired plants (see Annex 2,Table 22b). Fuel savings range from US$2.7 million to over US$4.0 million peryear (till 1994) and subsequently average US$4.3 million per year in financial

terms. The economic benefic of this power is equated to the tariff revenuecollected. From the commencement of power generation in 1989, this is aboutUS$6.16 million per year.-

7.04 Employment. As a direct resuir of increased agriculturalproduction, theLe will be a substantial increase in agricultural employment inthe project area. Three distinct peaks in Labor demand will occur due to theincreased cropping intensity. At full development, the incremental agricul-tural labor demand is about 8.7 million man-days (40.000 man-years), anincrease of abouc 65%. This represents an increase of 10.3 million man-days(47,000 man-years) or 89% over the present (see Annex 2, Table i9).

7.05 Flood control benefits have been taken into account in formulatingyield estimates. The Klambu Kanan and Klambu Kiri areas will predominantlybenefit from flood control. Improved municipal and industrial water supply isLikely to reduce the incidence of water-borne diseases in village and muni-cipal areas. Health benefits and possible fishing and recreational benefitsfrom the use of the Kedung Ombo Dam reservoir area have not been quantified inthe analysis.

Main Assumptions Used in the Economic Analysis

7.06 Financial costs have been converted to economic costs using thefactors in Annex 2, Table 14. Expected price increases and taxes have beenexcluded from economic costs. No shadow price has been applied to the cost ofanimal labor due to the shortage of animals in the project area. However, thelabor component of a team day (two mpn) has been shadow priced at 50% of themarket wage. The consequent conversion factor for an animal team-day is thus0.7.

7.07 Foreign Exchange. The exchange rate of US$1.00 = Rp 1,100 isconsidered to reflect the value to the economy of the foreign exchange used inthe project.

7.08 Operation and Maintenance. Based on updated estimates of O&M costsfor other multipurpose dams, O&M for the irrigation system alone is estimatedat US$15/ha/year. The system is expected to operate at about 502 efficiency.Annual O&M for the dam and reservoir is estimated at US$0.5 million andUS$0.13 million for the power plant (see Annex 9 for detailed costs).Equipment for O&M on the irrigation systems (US$1.72 million) and downriverworks (US$0.87 million) is replaced in its fifteenth year. Wal O&M for allirrigation and dam facilities per ha is about US$29/ha/year._

17/ After allowing 15Z transmission losses, negligible incrementaldistribution costs and an average tariff of Rp 98/Kwh in 1985 constantterms.

18/ Excluding O&M on the power component.

7.09 Economic Rate of Return (ERR). Based on the assumptions above and aproject financial and eccenomic life of 30 years, the ERR is estimated at about17.4% (17.6Z for a 50-vear scream) which is satisfactory. The flow ofeconomic costs and benerics over the project life is presented in Annex 2,Table 20. The ERRs for che irrigation and power components taken individuallyare 16.7% (Annex 2, Table 21) and 25% (Annex 2, Table 22a) respectively. Theequalizing discount rate for che power component taking only fuel saving is14.1Z (Annex 2, Table 22b).

Risks and Sensitivicy Analysis

7.10 The main risks associated with the project concern delays in landdevelopment due to delayed Land acquisition and inadequate operation andmaintenance.

7.11 If, due to deLayed land acquisition for the dam, construction costsare lagged two years and benefits are lagged more than two years, the ERRfalls to just under 13.4%. A future reduction in rice yields of about 12% inall areas except Sidorejo would result in a reduction of rice benefits ofalmost 20%. However, the project ERR will be 14.2%. If total benefits fell50%, costs should decrease to just over 20% for the project to remain viableat 10%, the opportunity cost of capital. Similarly, an increase in costs of50z could still maintain the project's viability at 11.8%. The project isless sensitive to cost overruns than to reductions in benefits, and theproject can withstand a reasonable degree of cost overruns and reduced bene-fits. Cross-over values for a number of critical variables are summarized inTable 7.1.

7.12 Varying Levels of O&M. The standard level of O&M assumed for theproject (para. 7.08) aims to produce an irrigation system efficiency of 50%. Theestimated impact of different levels of O&M on project beneg'ts was investigatedand summarized in Table 7.2. A cut in O&M budgets of 50% _t (very poor O&K)produ87d over time a system efficiency of 30%; poor O&M due to a cut in O&M of30Z ' resulted in system efficiency of 40%. In these cases, it is assumed thatO&M for the dam, reservoir, and the power component continues. In addition, itis assumed that the impact of the O&M changes occurs over 20 years. Due to thediscounting process, the ERR is little affected by the impacts of changes in O&Mexpenditures. Comparing the change in O&M costs to agricultural benefits overthe project life, however, shows a considerable trade-off. In the case of verypoor O&M, "savings" of US$1.99 million (NPV) in O&M costs result in losses ofUS$30.25 million in incremental agricultural benefits over the life of theproject. Similarly in the case of poor O&M, "savings" of US$1.31 million in O&Mcosts result in losses of US$8.58 million in agricultural benefits over the lifeof the project.

L9/ Complete neglect of maintenance and operational staff is also reduced.

20/ Costs of maintenance reduced by 60% but operational staff is not reduced.

Flood Forecasting and Water Monitoring System

Introduction

1. The flood and water supply monitoring system will consist of a net-work of sensors and telemetry to report meteorologic and hydrologic data inreal time to a central operations center equipped with computer systems andsystems softcware to fully automate the reception and archiving of data andtheir subsequent use. Computer models and applications software will be usedfor the purpose of forecasting floods, flood warnings, flow routing, andscheduling the delivery of irrigation water to diversion points. The contrac-tor who will be awarded the job will oversee the operations and maintenance ofthe data colLection, communications, computer system, and water control appli-cations for a period of four years after installation. During installationand the subsequent four-year period the contractor will provide training tothe Indonesian staff in all facets of operational activities.

Description of the System

2. The geographical area to be covered with the precipitation and waterlevel gauge network includes the upper catchment of the Juana River, as wellas the Serang-Lusi-Wulan catchment (see Map 18555). The Kedung Ombo Dam willcompletely regulate the flows of the upper Serang and will provide all of thesupplemental water to the Upper Sedadi (Sedadi) (13,900 ha) and the SouthCrobogan (Sidorejo) (6,100 ha) irrigation schemes. This is about 40Z of thetotal required. The supplemental water routed from Kedung Ombo to the JuanaValley (Klambu Kanan) (19,100 ha) and Lower Sedadi (Klambu Kiri) (20,400 ha)is augmented by the unregulated Lusi River (2,057 sq km) and the interveningcatchments.

3 Historically the Serang-Wulan and the adjacent coastal areas havebeen subjected to frequent and serious flooding from the Upper Serang and LusiRivers, and streams draining the southern slope of Mt. Muria. A comprehensiveprogram of channel dredging and levee improvements under Irrigation XIV (Ln.1811-IND) is under way to increase drainage and provide greater protectionfrom floods. However, the threat of flooding of Godong from the Lusi Riverhas not been reduced.

organizacion for Project Operation

4. Administration. The operation of a data collection network system,river flow forecasting, flood forecasting and warning, and scheduling ofsupplemental irrigation water will be managed from one water control center.This center will be located in Kudus.

- 141 - ANNEX 7Page 2

5. The Water ControL Center will be the technical arm of the irrigationcounictee which allocates water to the irrigation areas. During projectconstruction the Institute of Hydraulic Engineering (IHE) will establish aSubproject Office in the Jratunseluna Project Office and will be the agencyresponsible for implementing the data collection system, flow forecasting, andother water management activities. IHE, with project staff, will continue onand operate and maintain the Water Control Center for two years after theproject is completed. The Wilayah (regional irrigation) staff will be phasedinto the Center with the IHE staff during this period and ultimateLy willasvume management responsibilities.

6. Project Elements. The project proposal is to provide the ProvincialPublic Works Department (PU) with a computer-based real-time system for dataacquisition, communications, and hydrologic modeling tailored to the projectarea. Data acquisition includes point rainfall measurements, radar rainfalldata, and water levels in streams and canals, and at water control devices.There are nine basic program elements required to provide this complete waterresources management system: (i) network of data stations; (ii) MasterControl Center at Kudus; (iii) operations communications system; (iv) computersystem with software for data management, analysis and water control opera-tions; (v) training; (vi) four-year program of operations and maintenance forthe system; (vii) radar computer facility - Semarang; (viii) computer systemwith systems and applications software for process and analysis of radarrainfall data; and (ix) local support.

7. The entire program is designed for a minimum 20-year life. Thiswill be reflected in both the design and the level of training and support.All electronics will be estimated at a 10-year life.

Data Collection Network

8. A number of radio-linked precipitation and water level gauges willbe required to satisfy the data requirements for flood warning, flood controloperations, reservoir operation, forecasting and determination of watersupply, flow routing, forecasting irrigation water requirements, andscheduling and managing irrigation water delivery. Approximately 100 radio-linked precipitation event recording rain gauges will be required. About 60gauges will be installed in the irrigation areas. The spacing of the gaugesin the irrigation areas will be such that areas of approximately 1,000 ha canbe represented. These gauges will provide a measure of the irrigation waterderived directly from rainfall. About 40 gauges will be required in the UpperSerang (7), Lusi (22), Mt. Muria (5) catchments, and the reservoir (1) anddiversion structures tl).

9. About 86 radio-linked event recording water level and controlsensors will be required. At Kedung Ombo Dam, the reservoir level will bemonitored by a water level recorder installed in the intake tower. Inaddition, output will be monitored from two ultrasonic flow meters installedin the conduit supplying water to the power turbine and irrigation outlet.

-142- ANNE- 7Page 3

10. Radio-linked water level sensors and rain gauges will be used toestablish 12 stream gauging stations in the Upper Serang above Kedung Ombo Dam(2), the Lusi (3), the Juana (2) and the Mt. Muria catchments (4). Inaddition, a water level monitoring station will be established on the BumDrain and the Serang Lama River (see map 18555).

11. In the irrigation areas, water level sensors will be coupled withthe 60 radio-linked event recording rain gauges. The water Level sensors willbe used on the primary, secondary, and tertiary canals. This group of waterlevel sensors will provide a measure or the distribution and utilization ofthe diverted water volume in the irrigated areas. This information will beused in the assessment of irrigation water needs.

Central Control Center - Kudus

12. The master control center will be located in Kudus and will beequipped with communications facilities to receive and decode data transmittedfrom a network of about 120 field transmitters and one or more repeaters. Acomplete computer system and systems operations software to be linked to thecommunication system will serve the following functions: (i) receive data fromthe communications system; (ii) store received data in short- and long-termdata bases; (iii) provide alarm notification for floods and other significantevents; (iv) provide a maintenance logging function to aid in system diagnosisand repair; (v) interface with real-time radar rainfall data; (vi) provide agraphic display of telemetered data; (vii) provide real-time computer modelscapable of forecasting river flow, potential flooding, reservoir and diversioncontrol management, and irrigation water accounting; (viii) provide necessarycommunications to link WSR-74 WMS system with the computer in the KudusCentral Control; (ix) transmit operational instructions to reservoir anddiversion control stations; and (s) in addition the tenderer will furnish,install and operate a weather monitoring systetm in the Bureau of MeteorologyRadar in Semarang.

Radar Computer System - Semarang

13. The Radar Computer Facility will be located at the Bureau ofMeteorology in Semarang. The Facility consists of an EEC WSR-74-S bandmeteorology radar equipped with a digital video integrator and processor(DVIP) already in place and operational. A computer system, compLete withsystems and applications software, will be furnished and installed by thetenderer to provide real-time distributed rainfall amounts over the projectarea and also to provide a variety of rainfall and storm movement informa-tion. Models will be used to forecast firm and probable (as appropriate)short-term unregulated flow and reservoir storage in the system that isavailable for irrigation supply. The output will be used periodically by theirrigation committee to aLlocate and schedule water delivery to the irrigationareas. Given the irrigation water schedules, models will be used to determinereservoir releases, if needed, and to modify reservoir releases and flows inthe system during the delivery period in order to account for direct rainfallto the irrigated areas and for differences in projected and actual unregulatedflow supply.

-143 - ANNEX 7Page 4

14. Communications System. The network of rainfall, water level, andflow measuring sensors will be linked to che Water Control Center in Kudus bya line-of-sight radio communicacions system. The system will consist ofdemand- and event-actuated VHF radio transmitters at sensor sites,strategically located repeaters. and a central radio receiver in Kudus toprovide the interface between remote data stations and the central computerfacility.

15. Flood Forecasting and Flow Routing. The network of gauges providingreal time data for rainfall and water levels together with the computersystems and applications software will provide the following capabilitiesduring flood : (i) reservoir management for flood control and hydro poweroperation; (ii) rainfall-runoff simulations in the upper catchment areas,including Mt. Muria; (iii) flood forecasting and flood routing for reaches ofthe Upper Serang, Lusi, and Wulan Rivers; (iv) flood warnings for Purwodadi,Godong and at selected points in the lower reaches for levee monitoring andemergency spillway operations.

Water Accounting and Management

16. The data network provides continuous real time data related to thedelivezy of water to each irrigation area. Within each area the network ofrainfall gauges provides a measure of water supplied directly to the area.The water level gauges provide an index to the distribution of water withinthe system. Water level gauges will usually be located on secondary andtertiary canals. Whenever possible gauges will be located at existingparshall flumes or structures with fized control characteristics. Recordsfrom these gauges, used individually and collectively, will provide accuratereal time information of flows and water supply delivered to selected subareaswithin each irrigation area.

Cost Estimates

17. Annex 5, Table 4 gives the sumary of quantities and cost estimatesof equipment and services.

Implementation Program

18. The whole system will be implemented in four phases (see Figure1): (i) The first phase will involve the setting up of a flood warning systemin the Serang River during the construction of the coffer dam. This systemwill forecast floods upstream of the coffer dam and will give advance warningdownstream of possible dam break conditions. This system will have to becompleted by the 1986/87 wet season (September 1986). (ii) The second phaseof the system should be installed to perform the entire flood forecastingoperation for the Lusi-Serang Rivers through the center at Kudus in September1987. (iii) The third phase of the system should be installed to perform both(i) and (ii) and to do water allocation for the South Crobogan (Sidorejo) andUpper Sedadi (Sedadi) systems in June 1989. (iv) The fourth phase of thesystem should be installed to perform the entire flood forecasting operationin June 1990.
