DAMODAR VALLEY CORPORATION

Damodar valley corporation (dvc) is the first ever multipurpose river valley projects of independent india which came into being on july 7,1948 by an act of the consitutent assembly (act no .1948).

Dvc has its command area of approx 24,235 sq kms spreading across the Damodar basin,boundaries of which transcend the state of which transcend the state of west Bengal and Jharkhand.The upper Valley consist of two entire district (dhanbad and bokaro)and eight district partly(hazaribagh,koderma,giridih,chhatra,palumau,ranchi,Lohardaga and doomka) in the state of jhartkhand.The lower valley on the other hand consist of five districts partly (Burdwan and Hooghly,howrah,Bankura and Purulia) in the state of west Bengal.

Dvc was set up with the intent of promoting and operating the schemes which may cause social and economic uplift in the valley region.Dvc has already established its existence in discharging its obligation for more than five decades in perfect harmony.The difficult but effective water management by the corporation has already established.its existence in discharging its obligation for more than five decades in perfects harmony.The difficult but effective water management by the corporation has turned the devasting river Damodar from a ‘River of sorrow’ to a River of prospects and opportunities’.proficient management of water resources through dams,canels,and barrage,Dvc facilities irrigation as well as insustrial and domestic water supply which at a large benefited the region as a whole.it has also contributed significantly in conservation of soil and promotion of scheme of social integration in the valley area.

Dvc has been generating,transmitting,and distributing electrical energy since 1953 and has succeeded not only in meeting the expectation of the consumers but also has elevated its level of performance to a great height in the diamond jubilee year.no doubt during the course of the last 60 years,the scenario in power sector has undergone a sea change,yet dvc has maintained its lead role in the eastern region,adapting itself to the challenges of time and new technologies.

CORPORATE MISSION ,VISION AND OBJECTIVES

THE MISSION

Damodar valley corporation,the first major multipurpose integrated River valley project of the country ,conceived in line of Tennesse valley Authority(TVA) came into existance on july 7,1948 by an acts of central Legislature.

The mision at the time of its inception was:

Flood control Promotion and operation of schemes for irrigations Water supply for industrial and domestic use

Navigation and drainage Generation ,transmission and distribution of electrical energy Promotion of a forestation and control of soil erosion in valley area Promotion of public health,agriculture,industrial,economic and general well being

i damodar valley In keeping with industrialization in the DVC command area,power generation,transmission and distribution gained priority for providing electricity to he core industries like steel,coal,railways and other railways and other industries and consumers through respective state electricity boards.however other manded objective and general also received equal importance as part of overall responsibility and commitment of dvc.

This emphasis on capacity addition programme for power generation gained a new direction when ministry of power goverment o india started advocating for setting up f a thermal power plant at or near pits head and transmit power rather than transporting coal and advised DVC to world towards adequates capacity adition during the tenth and eleventh plan order to met the power vision 2012 of government of india.

THE VISION

FLOOD MODERATION

ROLE OF DVC IN FLOOD MODERATION

The river damodar proverbially erratic in nature is know as for recurrence of flood for over a century .the physiography of the valley by river damodar and its tributaries and the character of the network of the other rivers in the regions are in the main conditioning factors of the flood pattern in conditioning factors of the flood pattern in the damodar valley area and beyond.

THE RIVER NETWORK

Rising from the palamau hills in bihar the river Damodar flows in a generally south easternly direction for a distance of approximately 290 kms through bihar.on entering the deltaic plains of west Bengal below ranigung and after reaching the vicinity of burdwan the river aburuptly changes its course to a southernly direction spreading its water into a many channels.though the mains channels into a an insignificant stream,ultimately joining the Hooghly near shyampur much of its water drain into rupnarayan and the combined flow reaches Hooghly further south around 49 kms below Calcutta.

Its principal tributaries in the upper reaches are maulah,bokaro,konar,jamunia,and barakar.in the lower valley two other principal rivers flowing outside the Dvc command area.the floods of damodar and trans-damodar regions recurrent in nature have invariably been accompanied by pestilence,hunger,and epidemics.the situation climaxed in 1943 when the entire region suffered terrible loss of life and properties due to

the damodar floods which also led to worst ever famine in the region and dislocated trunk communications.hence serious efforts were undertaken to find out a permanent remedy to this chronic problem.

BIRTH OF DVC

A ten-man enquiry commited was set up which included the noted physicist dr meghanad saha and the maharaj of burdwan.this was followed by the adoption of Tennesse valley Authority model of the USA and induction of mr WL voorduin who submitted the preliminary memorandum for a compherhensive approach to tackle the flood of damodar and to harness the resources of the damodar valley region.based on these recommendation,damodar valley corporation came into being on 7th july 1948 as the first multipurpose river projects of independent india.the water management of dvc is also supported by Durgapur barrage which however does not have any flood moderation capacity but is used for temporary storage/balancing of water for irrigation industrial and domestic use.however since 1963-64 the responsibility of distribution of water from duragapur barrage through the canal have been handed over to the government of west Bengal.

WATER RELEASE:THE METHODOLOGY

Since 1964 operation of dvc reservoirs involving release of water during monsoon and non-monson (October-june )period is controlled by the damodar valley reservoirs regulations committee(DVRRC).The DVRR committe consist of two members each representing th government of west Bengal,bihar,and DVC under chairmanship of member RM central water commission(CWC).

The DVRRC decides about the quantam of water to be realeased as per the guidelines laid down in the reserviours regulations manual which has been formulated after a close study of relevant data to guide water realease at different situations.

PERFORMANCE OF DVC DAMS

The four Dvc dams have controlled a number of major floods in the lower damodar valley .there have been atleast 12 subsequent occasions when the peak discharge if unregulated would have been far in exess of the flow recorded in 1943,during September 26/27,1978,dvc reservoirs had a record inflow of 8.51 lakhs causes (hourly peak)of flood water.

FLOOD CONTROL CONSTRAINTS Due to the truncation of the scheme the flood storage capacity of DVC

dams and reservoirs has been reduced to one third . Non availability of land for utilization the full potential of maithon and

panchyat dams. Construction of tenughat dam with no provision for flood moderation in

place of proposed aiyar dam of DVC. Depletion in the drainage capacity of the channels below duragapur

barrage due to sedimentation and encroachment.

No provision for controlling floods caused by dwarekeshwar,silabati and other rivers in trans damodar area.

MEASURE REQUIRED FOR ENHANCHING FLOOD MODERATION CAPICITY

Construction of balpahri dam on barakar as proposed by DVC. Acquisition of remaining land at panchyat & maithon. Unified operation of Tenughat dam with DVC dams. Improvement of the drainage channels in Lower damodar area. Steps for enhancing checks and balanced to combat silt inflow into

reservoirs and drainage channels. Implementation of integrated flood control scheme including other

rivers (such as Dwarkeshwar etc) in the lower damodar areas.

THE PLAN AND AFTERMATH The initial plan enviased construction of seven dams including two on damodar(panchet and aiyar) three on baraker (maithon,balapahri and Tilaya) and one of the konar and bokaro river with a view to moderating a deign flood of 10 lakhs causes to the levels of 2.5 lakhs cases.

TRUNCATED CAPACITYOut of these seven proposed dams only four have been constructed by dvc in the first in the phase of its construction and others could not materialize due to the reasons beyond dvc control.the four dams in the dvc system include panchyat on damodar ,maithon and tilayia on baraker and konar which cam at best moderate six lakh causes of flood water to 2.5 lakhs causes of flood water to 2.5 lakhs causes level. The four dams constructed by DVC were supposed to have a total reservoir capacity of 25 lakhs acres feet excluding dead storage.out ofthis capacity of 15 lakhs acre feetwas earnmarked for flood control but due to non –availability of full requirement of land,five lakh acre ft thus limiting the ability of dvc to one third of the original plan. Further,the position is compounded by the facts that valley iethe region below the dvc dams can itself generate a flood of 2.5 lakhs ft/sec and the original plan assumed that separate flood control

arrangement including improved drainage system would have to be made for protection of the trans-damodar areas which is affected not only by floods of damodar but also by floods of rivers like dwarakeswar,kangsabati,silabati and others which are not part of DVC water management network. DVC OBJECTIVES

DVC is working with the following objectives since formations:

Flood control; Irrigation and watyer supply for industrial and domestic uses; Generation,transmission and distribution of electrical energy; Soil conservation and afforestion; Socoio economic uplift of the people in the valley area;

DVC VALLEY

The total valley areas covered by DVC is around 24,235 sq.kms.upper valleys covers six districts fully (hazaribagh,koderma,giridih,chatra,dhanbad,bokaro) and four districts partially(palamau,ranchi,lohardaga and dumka) in the state of Jharkhand.lower valleys fall into two districts fully(burdwan,and Hooghly)and three districts partiaaly (howrah,purliya) in he state of weste Bengal.

The Maithon Gas turbine has been setup by DVC in October 1989, Constructed & commissioned by m/s GE, USA on Turnkey basis with total cost of setup of $ 2702.

. Reservoir operation

A vast hydro meteorological station with VHF/wireless facilities exists

over the Damodar catchment area. On a real time basis (hourly, 3

hourly, 6 hourly) data of river gauge, rainfall river discharge are

measured and transmitted through existing communication network to

the central flood station at Maithon. The Indian Meteorological

Department(IMD), Kolkata, transmit the rainfall forecast for the next 24

hours for the entire Damodar Valley region to Maithon. A computer

model at the Flood Forecasting Unit(FFU) at Maithon estimates the

inflow into the reservoirs based on the real time data & rainfall forecast

of IMD.

According to detailed guidelines contained in the “Damodar Valley

Reservoir Regulation Manual”, Member Secretary of DVRRC

(Damodar Valley Reservoir Regulation Committee) after discussion

with SE, Damodar Irrigation Circle Govt. of West Bengal, Reservoir

Operation of DVC & SE, Tenughat of Govt. of Jharkhand decides day

to day release of water from Maithon Dam

Problems

People involved in power generation say that water should be filled up

as much as possible as it would be better for power generation. People

involved in flood control department says water storage should be

lowered, so that in case of excessive rain a flood like situation arises

then it will be a flood cushion. This is a conflicting nature, so water has

to be kept at an optimum level to satisfy both parties

Dead Storage Capacity of the dam during the initial years was much

more than the storage capacity now.The portion of a water storage’s

capacity that is equal to the volume of water below the level of the

lowest outlet (the minimum supply level),is known as th Dead Storage

Capacity. This, increase has been mainly due to the sedimentation

storage. Due to human & industrial activities, the storage capacity has

decreased over the years. As per the design of dam given by Mr.Voord

capacity depth should have been 500 ft (150 m). But due to non-

acquisition of land the depth is at 495 ft (151 m). The carrying capacity

of the dam as designed by Mr.Voodro was 1,000,000 cu ft/s

(28,000 m3/s). But at the time of construction it was only

250,000 cu ft/s (7,100 m3/s) and at present it has a carrying capacity of

less than 100,000 cu ft/s (2,800 m3/s). The cost of removing deposited

silt in the dam is equal to the construction of a new dam,therefore

economically not viable. If the silt is removed and stored in the banks

of the dam, then during monsoon the silt would get washed off into the

dam.

Maithon Dam has completed 60 years.

MAJOR ISSUES FACED BY DVC

• LAND ACQUISITION

• REHABILITATION AND RESETTLEMENT

• FLOOD OPERATION

• LOWER DAMODAR CHANNEL CAPACITIES

• OPERATION OF THE TENUGHAT RESERVOIR

• ACTIVITIES WITHOUT KNOWLEDGE OF DVC

• ENVIRONMENTAL IMPACT

• CAPITAL SHARING

• FUND

• ILLITERACY

• POLITICAL WILL

• EMPLOYMENT

• EXTRACTION OF FULL BENEFITS (TPD ETC)

• EROSION & SEDIMENTATION

• SHARING OF WATER

• TECHNOLOGY

• LACK OF PRO-ACTIVE PARTICIPATION OF STAKE HOLDERS

STRATEGIES TO COMBAT ISSUES

• FLOOD CUSHION OF TILAIYA AND KONAR RESERVOIR MAY BE USED AS A COMBINED STORAGE FOR FLOOD AND CONSERVATION STORAGE

• IF EXTRA WATER IS MADE AVAILABLE, IRRIGATION FACILITIES MAY BE EXTENDED TO JHARKHAND STATE THROUGH KONAR AND TILAIYA RESERVOIRS

• IN CASE OF MAITHON AND PANCHET, EXISTING OPERATIONAL CONSERVATION LEVEL MAY BE INCREASED BY 1.52 MT. IN EACH RESERVOIR

• ALL M&I WATER ALLOCATIONS MAY BE REVIEWED TO LOCATE SURPLUS IN THE ALLOCATED QUANTITIES

• TO COMBAT THE FLOOD AT THE LOWER VALLEY, DOWN-STREAM FLOOD CARRYING CAPACITIES MAY BE REVIEWED AND MEASURES FOR IMPROVEMENT OF CARRYING CAPACITY MAY BE TAKEN

• ADEQUATE AFFORESTATION AND SOIL CONSERVATION MEASURES ARE ALSO REQUIRED TO BE TAKEN UP AT THE UPPER VALLEY TO REDUCE THE EROSION RATES

• TO TAKE UP RAIN WATER HARVESTING AND GROUND WATER RECHARGING PROJECTS

• RENOVATION OF OLD IRRIGATION & WATER SUPPLY CANAL SYSTEM AND IMPLEMENTATION OF MODERN IRRIGATION TECHNIQUES FOR OPTIMUM USE OF THE RESOURCE
