IV. Water source selection

Bod Nguyen reservoir has been under the management of Hatinh fresh water trading

company since 1994. The water level of the reservoir is stable at level +18.40 to +18.00.

Water at these levels will run itself to the treatment plant. Water from Boc Nguyen reservoir

was proved by previous projects (funded by Australia government) to be good in quality,

stable in capacity and cheap in transporting. According to forecast calculation, if only

supplying water for local life and industry, the current capacity of the reservoir is enough in

the next several years. So in this project (with the design capacity up to 24000m3/day), the

consultant recommends using Boc Nguyen reservoir as the raw water source for the project.

The consultant recommends building a new water intake structure and installing vacuum

pumps, leading raw water from Boc Nguyen through the surface of dams because of the two

following reasons: (i) the existing intake structure has some damage (The pipe system from

float to the main pipe at level +6.50 is damaged so water at these levels can not be gathered.

The water which is gathered mainly from the bottom layer( level +6.50) is difficult to treat as

i t is contaminated with mud); (ii) when increasing the capacity, a new raw water conveying

pipeline must be installed, but it's impossible to install pipes through dam.

In order to enable the WSC to comply with the requirements of Operational Policy 4.37 of the . t World Bank the Specialist shall render the following services to the WSC.

- inspect and evaluate the safety status of the existing Boc Nguyen dam, its

appurtenances, and its performance history; - review and evaluate the operation and maintenance procedures of the dam operator;

and - review and evaluate any Emergency Preparedness Plans (EPP) for the dam, and the

necessity of any such EPP - provide the Client a written report of findings and recommendations for any remedial

work or safety-related measures, improvements in O&M activities or EPP necessary to

upgrade the existing dam and its operations to an acceptable standard of safety. - assess the adequacy of the flood release works of the dam - In addition to the prevailing Vietnamese dam safety Standards (TCXDVN285-2002

and QP VN 11-77) the dam shall also comply with the standards adopted in 2001 and

2003 by the World Bank for rehabilitation of dams under VWRAP.

Intake structure and gravity flow conveying pipelines are expected to be built (siphon type) at

the north of Boc Nguyen reservoir 910m far from treatment plant. The water intake, in

reinforced concrete compartment type. has an inlet hole at level +14.5m. A road to the intake

will be built with the length of 150rn. structure of scree concrete, width 2m.

V. Nature and administration 5.1. Location

- Hatinh town is lhcated at 18'22' of North latitude and 105" 56' of East longitude.

Situated 360km South of Hanoi, Hatinh town is along the National Road 1 A .

+ Area of town: 3,065.38 hectares (Urban area: 476,58 ha, suburban area : 2,588.8 ha)

+ Hatinh town is bordered by Cau Cay River -Cua Sot River to the North

+ Hatinh town is bordered by Cam Binh commune-CamXuyen District to the South

+ Hatinh town is bordered by Cay river, Thach Dai to the West

+ Bordered by Thach Khe, Thach Dinh of Thach Ha district to the East

5.2. Clintate

- Hatinh town is in the tropical monsoon climate region:

+ The annual averagc air temperature : 23.9"C

+ The monthly highest average air temperature : 29.4'C

+ The monthly lowest average air temperature: 18°C

+ The absolute maximum of air temperature: 41.1°C

+ The absolute minimum of air temperature: 7°C

+ Annual rainfall average : 2,548 mm #

5.3. Topography

- Situated in the centre coastal delta enriched with alluvium from rivers and sea, Hatinh

town has low terrain. The ground level of the town is from +0.5 + +3.0 m with gradually to

the Northwest and Southeast.

+ Constructed in the urban area: level: +2.0 s +2.5 + +3.0 m;

+ in the suburban area: level: +1.0 + +2.0 i 2.30m;

+ in the rice-field around the town: level + 0.5 + +1.0 m;

+ in the area around Rao cai river, the level is very low: 0 i -1.5m

- In rainy season, the whole town is submerged (below the highest water level). Therefore, a

strong dyke system was built around the Rao cai river and Cay river to protect the town and

neighboring area. The water level in Rao cai river can be +2.8m in rainy reason. As a result,

the town and neighboring area will be submerged in water in case of heavy rain.

5.4. Hydrographic Characteristics

a. Groundwater;

According to the Geo-hydrography document at the scale of 1:50,000 provided by 2F geological group, the water containing layer ha3 large capacity and wide range. However the

..\atel- here i s not used as the salty content esccccl5 ?"',.,, . The water with lower salty content is


in area far from the town. There is a underground water source in some area however the

quality and quantity do not meet the requirement.

b. Surface water

- The biggest river in the area is Rao Cai river with basin of 516 km2, springing from

Dai Son mountain which is adjacent to Ky Anh, Qmax = 30 m3/s, Qmin = 0.2 m3/s

- Hmax = +9.87 ; Hmin = +1.79

- Cmax = 9.91 gl cm3 ; Cmin = 1.3 gl cm3

- However. when the Ke Go Irrigation system is completed, the Ke go reservoir will

play regulating role for the area of 223km2. Therefore, in dry season, the source is dry, salty

water breaks into hinterland, its edge is lOkm far from Cau Phu up to the upstream part with

salinity of more than 0.005.

Rao Cai river is not useful for supplying water, it only contributes to drainage and river

traffic of the town.

Ke Go reservoir and Boc Nguyen Reservoir should be paid special attention when

studying water supplying area.

- Ke Go Reservoir:

Ke Go Reservoir is located at 13km Southwe? of Hatinh Town. The water flow from e

upstream part of Rao cai River is led into Ke Go reservoir. The area of this reservoir is

223krn2 with the flowing frequency 0.001: 3,650 m3ls.

+ Normal water rising level + 32.27

+ Water rising level with frequency P : 1'1 oo; H : + 34.77

+ Fixed water level Hc: 14.47

+ The whole capacity W: 345 million m3

+ Useful capacity WH: 320 million m3

+ Fixed capacity WC: 25 million m3

Ke Go reservoir is also designed to be used for supplying safe water for domestic and

industrial use with capacity 1.6 m3ls. However, the reservoir should be considered as an

useful source when the water supply capacity of Hatinh town is more than 50,000m3I24h. The

long distance from the consumption area is the disadvantage of the reservoir.

- Boc Nguyen Reservoir is smaller than Ke Go one. It is lOkm far from Hatinh Town.

+ Area of reservoir: F = 32 km2

+ Capacity: W = 22 million m3

+ Normal water rising level: Hd = 14 (m).

+ Level of existing spillway crown: H@ = 18.4 (m).

+ Level of designed spillway crown: Htk = 22 (m).

+ Elevation of fixed water level: Ho = 10.5 (m).

+ Level of culvert bottom: Hc = 6.5 (m).


- The reservoir has been under the management of Hatinh Water Supply Company

since 1997 with the purpose to supply water for Hatinh town. I

Some notes of underground water in the- area of project

+ All most wells in the local people are contaminated by Coliform, Feracoli. the

amount of Coliform and Feracoli at level 150-250 MPN1100 ml and 10-20 MPNl100ml. The

limited values of VNS TCVN 5944-1995 for colifrom and Feracoli are 3 MPNI100 ml and 0

MPNIIOO ml.

+ NO2- concentration in some wells can reach up 4,5-5,O mg/L but the limit of its for

drinking water according to The stipulation of the health ministry is 3 m d L

+ NH4- concentration reachs 2,O -6,5 mgll the allowable limit of dringking water

standard of the health ministry is 1,5 mg~l .

(2) Surface water

- The biggest river in the area is Rao Cai river with basin of 516 km2, springing from

Dai Son mountain which is adjacent to Ky Anh, Qmax = 30 m3/s, Qmin = 0.2 m3ls

- Hmax = +9.87 ; Hmin = +1.79

- Cmax = 9.91 gl cm3 : Cmin = 1.3 g/ cm3

- How'ever, when the Ke Go Irrigation system is completed,' the Ke go reservoir will

play regulating role for the area of 223km2. Therefore, in dry season. the source is dry, salty

water breaks into hinterland, its edge is lOkm far from Cau Phu up to the upstream part with

salinity of more than 0.005.

Rao Cai river is not useful for supplying water, it only contributes to drainage and river

traffic of the town.

Ke Go reservoir and Boc Nguyen Reservoir should be paid special attention when

studying water supplying area.

Ke Go Reservoir:

Ke Go Reservoir is located at 13km Southwest of Hatinh Town. The water flow from

upstream part of Rao cai River is led into Ke Go reservoir. The area of this reservoir is

223km2 with the flowing frequency 0.001: 3,650 m3ls.

+ Normal water rising level + 32.27

+ Water rising level with frequency P : 1'1 oo; H : + 34.77

+ Fixed water level Hc: 14.47

+ The whole capacity W: 345 million m3

+ Useful capacity WH: 320 million m3

+ Fixed capacity WC: 25 million m3

Ke Go reservoir is also designed to be used for supplying safe water for domestic and

industrial use with capacity 1.6 m31s. However, the reservoir should be considered as an


useful source when the water supply capacity of Hatinh town is more than 50,000m3124h. The

long distance from the consumption area is the disadvantage of the reservoir.

Boc Nguyen deservoir is smaller than Ke Go one. It is lOkm far from ~ a t i n h Town.

+ Area of reservoir: F = 32 km2

+ Capacity: W = 22 million m3

+ Normal water rising level: Hd = 14'(m).

+ Level of existing spillway crown: HO = 18.4 (m).

+ Level of designed spillway crown: Htk = 22 (m).

+ Elevation of fixed water level: Ho = 10.5 (m).

+ Level of culvert bottom: Hc = 6.5 (m).


VI- Environmental impacts and mitigatingmeasures

General impacts of the project are positive because the project will be going on improvidg

stability of supply water service and areas are supplied water will be spreaded into sub-areas

of Hatinh town. The project would have done, it will provide enough water to the period of

2010-2015.

W.1-The environmental impacts and mitigating measures during building and improving

of the treatment facilities

I -Land requisition

Thc project sitc is in thc area of the currcnt water factory, so there is no affect on the land

requisition. The total current land area is 3.5ha. During designing the water treatment plant in

the first phase, the land is required for second phase included.

2. Destroying flora

The invested works in water treatment factory will include the installation of

supplementary devices such as: dosing pumps, chlorine feeding system, replacement of two

new Chlorine dosing pumps, 2 electronic scales and two chlorine bottles. These works above

are carried out inside the area of the factory so it will not make any effects on the flora inside . and outside of the factory.

3-Flood

Similarly, the installation devices in the factory will not affect on hydrographic net as well as

flood in this area.

4. Soil environment, eliminate dust and noise

There are not any works that have to execute so these effects are excluded completely

5. Security for the station

All works are inside of the station, there are fences around and security guards are on duty on

24 per 24 hours every day so that security proplem for the station are ensured completly

5. Sanitation proplem and environmental pollution risks

No effects cause to ground water or hygiene by the installation some devices in the factory as

the description above.

7. Safe problem in working

The installation of some devices above is completely simple and has little risk of unsafely

labour.

8. Drainage


From 2005, the water factory have completed in enhancing treatment capacity up

24.000m3/day-night. The supplementary works consist of the upgraded drainage system and

an improved water treatment plant of 100% capacity.

VI.2. The environmental impacts and diminished measures in liberating space and building

transmited and distributed routes phase.

11.2.1. Land requisition

Impacts during this phase relate to the temporary land use, land acquisition, property

compensation, economic damage and move tombs. However, this project is built up based on

the plan of phase 1 and the almost works existed during the first phase project. Moreover, the

project will not relocate affected people, resettle people and permanently acquire the land.

Most of land acquisition for the project is the public land, it is not go through residential area.

There are no vestige and historic, cultural sites in the project site and area surrounding.

1 - Effect range

Effected range of the project consist of: transmitting pipe routes and distributing nets

and they go through Hatinh city and Thach Ha district.

Thach Ha district consists of 4 communes: Thach Huong, Thach Tan, Thach Lam and

ThachtDien and 2 towns: Thach Ha, Ho Do. rn

Ha Tinh city consists of wards: Tran Phu, Bac Ha, Tan Giang, Dai Nai, Nam Ha,

Thach Trung and 7 communes: Thach Dong, Thach Mon, Thach Hung, Thach Binh, Thach

Linh, Thach Trung, Thach Ha, Thach Yen.

2-Effected objects

+ There are no works due to people relocation and resettlement . + Temporary residential and agricutural land acquisition

+ Temporary or permanently property loss, this amount is not much and the fortune is

not too much. Effected objects are mainly next to or on the ground where to work pipe rounts.

The fortune has to be broken down that includes: Contemporary house, tents, bussiness kiohs,

play grounds, fences, entrances, asphalt or concrete roads, electric wires, water pipes,

telecommunication cable.

+ Invading cultivated land and tenred land: they will be affected in working process

that is the highest rate. All households above next to or on the working space.

+ They make affect to bussiness but also are not much and affect in working. All

households above next to or on the working space, time to working is not long so the demage

is not serious.

+ Effect to cultivation, farm product and plans, these households also nest to the space

of the working thc pipe nctq


3-Assessing the rate of effect on every works (articles)

Receiving work and raw water pipe route

The receiving work will be built on Boc Nguyen Lake that outside the management of

the water Ha Tinh company. The design and work will affect to the safety of the lake.

T o ensure for dam safety during construction phase, the project management unit will

hire an expert to assess the safety for Boc Nguyen Dam and suplementary units and suggest

the suitable solutions to investor for dam safety including processes of managing, operating

and maintaining the dam. Experts will have done services following:

a- Inspect and assess the safety of Boc Nguyen dam and suplementary devices

b-Consider and assess processes of operating and maintaining of operator.

c-Consider and assess planned programes and to be ready when the dam has troubles

and the necessary of the those programs.

d- Provide the investor discoveries and proposals for any maintains or measures that

concern to dam safety, improvements of operations and maintenance or emergency programs

when the dam has any troubles to improve the dam and its operation for meeting the safe

standards.

The inspection a n d consideration allow the investor doing repairs, maintenance,

improvement of the dam and suplementaty works as needed as well as emergency programs

when it can get problems. Experts are not required to do geological survey or other checks to

investigate the seepage, stability or other phenomenon relating to dam safety, but the experts

should propose some advices to the design works. Especially, the experts will assess the

feasibility of spillways of the dam, besides the safety standards of the dam are using very

popularly in Vietnam, the dam will has to comply the standards that have been selected by

W B in 2001 and 2003 under Vietnam Water Resources Assistance Project (VWRAP)

Moreover, the construction work can effect to water quality and water supply demand for

the city. The mitigating measures would be mentioned clearly in the pages of 35 and 36 of

this report.

Tranship route

The transship pipe route will have distance with route 0 3 7 5 about 2m toward the

transport landmark, hence need to clear the route about 5000 m on cultivated land with the

square about 15,000 m' and 1,800 m go through land tenure with square about 2,600 m'.

Pressure station in Dai Nai

At the pressure station in Dai Nai % i l l only build a new pump station and a tank with the

volume about 2000m3. and the land '11 present is enough square for 2 these works

Construction Can affect on \ i a l i ' ~ \ L I I - ~ ) ' . 1 , ' . : \i hen 2 these works copnect with old net.


Pipe routes in the water supply system

To clear the ground to construct pipe routes inner the city are very complicated because on

the pavement areas have narrow horizontal face but also have many technical systems: the old

water supply system, the drainage, telecommunication cables, electric cables, plants, all of

them had been programmed overall. On the other hand, popular density is very high and

substructures were completed. All of these routes are operating so that have much difficulty

when execute the work.

The land clearance for pipelines construction inner the city is simpler, however the land

need to build the routes along pavement which has to be finished. Many pipelines are getting

troubles in construction because of land acquisition issue. Therefore, we should consider the

realizable construction schedule of the project. It needs the supports of the local government

and authority sections

Vl.2.2 Annoying for local people and business units

Although the square of temporary land requisition is not much, there are not household

have to migrate but also this work will make the change, disorder the living of the owner. If

the clearing the ground and compensate are not good, it can make negative social effects: such

as: appeal, make the social disorder and affect on carrying project out. For example: the cost 8 0

of compensate in some areas can be lower than the truth cost of in the local or we have to

suitable policies to aid households if not their living will have changes and need much time to

stable and this is the cause of social conflicts.

Moving tombs in the country is sensitive problem. All most people do not want move the

tomb because this is spirit, custom and the culture of Vietnamese in general and the local

people in particular. S o that may make negative reaction of households which have the tomb.

In addition, The difficult in moving the tomb to the new area is the important problem that

need to consider carefully.

Besides, it can affects on bussiness but these affects are not much and if happen just only

happen in executing the work becausr these households is next to or on the ground where

install pipe systems. The time working of each phases only happen from 2 or 3 months so

damage meansure is not much, people can restore completely the bussiness after

These problems are the most potential effects of the project so that the arrangement in

clearing surface, compensate have to work out.

1 - To clear surface

After the project was agreed, the water supply Hatinh company will carry out building

the programming clear surface with the full of content according to constitution, law,

professional departments and the requirement of WB. After the programming of liberating the

departments, the water supply Hatinh company will announce and co-ordinate with Thach Ha

people district committee, Hatinh city people committee and communes, wards to establish

the liberating the space group in there the water supply Hatinh company is one of the

members. The responsibility of the water supply Hatinh company deploys the content of the

programming of liberating the space to locals in the project area and to complete procedures

following:

Announcing policies of authority departments to locals about the programming liberty

the space of the project.

Contact and work with the local authority to deploy establishing organization system

in compensating the liberaty the space and set up a mechanism working with the local areas in

requesting the procedure for land requisition.

Agree with the province people committee in building and spread out compensate

policies, unit price project following:

Determination K coefficient (according to circular 145/1998/lT-BTC dated on

411 111998 of final ministry) to determine land cost, determine other fortune to make the base

to calculate the worth of compensate damage.

@ Specific policies about the compensate, support.of the project will base on WB regulations

and carry out clear surface.

The clear surface committee will organize and carry out the liberate the space consist

of: compensate: land, fortune, the damage in producing process, business of the local people,

the state units, the public works that consist of the works on the ground or underground.

The operation of the library the space committee will be regulated and guided

according to the circular 145/1998/IT-BTC date 4/11/1998 of the final ministry and decree

197/2004/ND-CP of the government about compensating the damage when the State land

requisition for national defense, security, and national benefit, public benefit in addition

appling the special policies of WB for project. The liberary the space committee of project are

set up with managers of province, districts, communes. Beside the water supply company

Hatinh is the member of the liberary the space committee but also establishes a working group

responsibilities following:

-Provide document that relate the project

-To announce on public medias about plan construction: scope of the project that

concern to organizations, units and the local people.

-To stranfer landmarks to the local liberary space to count, measure and have

compensate plan in time. In the constructing process of the projec~. if to have correction and


edition the location of construction that can change landmarks, the working group will

announce, explain for units, communities , the local communities and the local people.

- Usually, combinate, monitor, inspect in compensating the liberary space consist of:

meansure, inspect in compensation unit price, support in the scope of decree 197/2004/ND-

CP of government and the policies of WB.

-To limit the effect on the Environment, movement, compensation for technic

infrastructures such as: electric lines, communication, water drainage and supply, irrigation

canals, underground contractures, roads ... are called public constructions, will have plan

according to the rules

+ Objectives of resettlement

Objectives of the laws of Vietnam about resettlement and recovery for displaced

people and objectives of the World Bank in compulsory resettlement are applied to make this

resettlement plan. The objective will be described below. Matrix of entitlement is illustrated at

Appendix 1 for reference. Policies and principles applied to this project will be applied to

replace differences between the current regulations of Vietnam and policy of the World Bank

(OD 4.30).

The main objective of this Resettlement Plan (RP) is to ensure that all Project Affected

Persons (PAP'S) will be compensated for their losses at replacement cost and provided with

rehabilitation measures to assist them to improve, or at least maintain, their pre-project living

standards and income earning capacity.

+. Resettlement principles

The principles of resettlement of the project:

a) Mitigate people's lands and property acquisition.

b) Everyone whose life, work, business or farming will be affected when his land is

expropriated, will receive compensation to improve or at least restore his life standards,

income and production. Having no rights to use their land does not mean that they will not

receive that such compensation.

c) Compensation measures are as follows: (i) Compensation is at replacement cost

without deduction or depreciation of salvaged materials of houses or other structures; (ii)

Agricultural land will be compensated by land with similar productive capacity, which is

suitable for the affected person; (iii) Replace residential lands with lands (if possible) with

similar area, suitable with affected people; (iv) Support transportation and life cost; and (v)

Subsidize to restore their source of income or means of subsistence.

d) Lands used to compensate for agricultural lands and residential lands should be as near the acquired lands as possible. The land must be satisfactory for the people. If the area of

acquired land is small (less than 20% of total area of house), i t can be paid in cash if that is

selection of affected people, or if there is no land available for land cornpensarion. I


e) The resettlement transition period must be shortened to the minimum. And affected

people must receive resettlement supporting measures more than 1 month before the work

takes place at thelocation.

f) Affected people must contribute to planning for acquiring land and other property.

proposal of a solution to resettlement, to make the resettlement satisfactory for everyone.

Affected people will receive their legal interests more than 1 month before the work takes

place at the location.

g) Public services or resources must be preserved or improved.

Budget for land compensation and resettlement must be prepared in every part of the

project. Conditions for resettlement must be in advance when needed.

h) WB will not approvc contract of any pro-ject using the loan when compensation

hasn't been completed and resettlement budget hasn't been firmly prepared before the

execution. Affected people's rehabilitation assistances must be ensured more than 1 month

before the work takes place at the location.

i ) Authorities must ensure the effectiveness and timeliness of design, planning,

consultation and implementation of RAP.

j) Independent evaluation and monitoring mechanism must be defined as part of the

compensation managemept system. The assessment of land acquisition procev and final

result of the project is made independently with authorities.

+ Compensation for Permanent Loss of Agricultural Land Compensation policy for the affected people will be provided as following:

(a) The general mechanism for compensation of lost agricultural land will be through

provision of "land for land" arrangements of equal productive capacity, satisfactory to the

PAP. If land compensation size is smaller or lower quality, PAPs will be entitled to

compensation on cash equivalent the differences.

However, if land is not available or the PAPs prefer to receive cash compensation,

then the following applies:

Legal and legalizable land users:

(i) if the portion of the land to be lost represents 20% or less of the total area of the

landholding, and the remaining land is still a viable economic holding, cash compensation for

the lost area (or for the entire affected plot if the remaining area of the plot is not

economically viable), at full replacement cost, may be provided to the PAP, or

(ii) if more than 20% of a household's agricultural land is acquired, then in addition to cash

compensation at full replacement cost for the lost area (or for the entire affected plot if the

remaining area of the plot is not economically viable), the Project will provide a rehabilitation

allowance of value not less than VND 3.000.000iHH

Users with tenlporary or leased 1.ighr.r ro r ~ s e lunrl:

This should be adjusted annually with inflation.

VI.2.3. Effects to transport means and pedestrian Thess effects would happen mainly concerning to dust, air pollutants and noise generation. Dust, smoke, noise will affect on the people living nearby the construction area. Although, the pollution only happen in local, however some parameters which effect to the health will consist of dust, noise and ingredient of air pollutants emission such as CO, NOx, SO2 ... Besides. the impacts of air pollution would cause by traffic jam or solid waste dumping. This effect will be mentioned later.

VI.2.4. Dust, gas elimination 1-Effects by air polluted emitting from engines

The air polluted generate from operation of construction machines, transport means such as: lorries, machine hammers, drills, electric generator, concrete mixer. The main ingredients causing the air pollution are dust, S02, NOx, CO and other volatile organic compounds (VOCc). According to the data of WHO:

+ When burning 1 ton of diesel oil, about 4,3 kg suspend dust, 64 kg S02,55kg NOx, 28 kg CO, 12 kg VOC will emit into the air + When burning 1 ton of petrol , 3-5 kg dust, 64 kg SO2 and 30 kg VOC will emit into the air

Objects that affected by air pollution are workers and people living around construction site about 200m. In this area, in the dry season and on rush construction time, because of mobilizing many transport devices and construction machines, the pollutants's concentrations v.~ill increase 2-5 times comparing with the environmental quality at present that mentioned in chapter 3: higher than TCVN 5937-1995 (applicarion for ambient air), but they are lower than


the air environmental quality standard at work that promulgated according to decision No. 3733/BYT/QD of the Ministry of Health.

w

2. Pollution by dust

Dust generates from activities such as excavating and cutting soil, transport means in transferring and disbarging construction materials of cement, sand, stone and gravel. At present, there is not any researches providing the data about air pollutants emission coefficients in construction activities. In reality, the air pollution level from constructions depends on natural conditions as well as construction methods. Dust will be generated much more and the effected scope is higher comparing to it is not sunny and windy.

Dust concentration in the air predicted reaching the average level from 5 to 15mg/m3 in sunny, dry, windy days and can goes up to 50-70mg/m3 at points that uncharge soil, sand, cement. In the scope about 200m from construction, dust concentration in the air still measure about 2-5 mg/m3, and higher than permitted level according to VNS (TCVN) 5937-1995 and decision No 3733-BYT/QD of the Health Ministry (TC 3733-BYTIQD). Dust concentration in the air will decrease strongly compare with predicted level about 0,3-0,s mg/m3 on raining days.

Dust pollution in transporting process materials will affect on the large scall. Dust pollution intensity cause to the air a lot or a little depend onlmany weather factors and transporting routes. Especially on sunny days, windy, dust concentration is usually higher many times than the air standard around, the effected scope by dust is all of the square of the project.

Mitigating solutions: - On the dry and sunny days, the contractors will water on main roads, the innedcenter

area of city to limit dust. - All means that transport construction material such as sand, clay soil, cement and

stone have to cover to limit the dust dispersion into the air environment. - Concrete mixers, asphalt stations have to be located far away from high density areas

200-300m or more (called safe distance). If the concentrations of dust, S 0 2 , N02 , CO, VOC emitting from concrete mixers, asphalt stations is higher than the limited values in TCVN 5939-1995, it needs to install a control device.

- Air pollutants emit from construction machine (transport means, lorries, bulldozers ...) and asphalt stations need have to monitor according to TCVN for transport means to control the air pollution caused by dust, S 0 2 , N02 , CO and VOC.

High noise in construction phase generated by transport means, bulldozers and concrete- mixer. The above activities will generate high noise in the range of construction sites and the areas around roads.


Minus pressure level generated from some transport means and construction machines are summarized in the table 6. The minus pressure level will be higher when many transport means, devices and machines are operating at the same time:

Hot asphalt spreading vehicle 80-85 I

The highest noise level at the position where is away from the mixing station about 15m with concrete-mixer is 90 dBA in uncover condition, the noisy level at double distance goes down 6dBA. Therefore, the noisy level at the distances of 30m, 60m and 120m from concrete mixers are 84, 78, and 72 dBA respectively.

80-85

85-90

Vietnam noisy standard stipulating the standard noisy level in the popular area on day is not over 60 dBA. If the concrete-mixer operated on day, It has to local far the popular area at least 300m, the trade area at least 240 m. If it is an innovative concrete-mixer that can make the noise about 75 dBA at the local 1 5 m distant, at 60 m distant only 63 dBA.

b. T o load and unload operation soil and smooth the surface

T o smooth the surface w e need some machines and devices such as: excavator, bulldozer, and lorry. These machines and devices can make noisy level about 90 dBA at 15 m distance. If they operate at the same time, the noisy level will be resonant, for example 6 machines are working at the same time can make the noisy level 97-98 dBA.

c. Electricity generator

The noise level comes from electricity generator can reach to 8 2 dBA at 15m distance, so that the highest noisy level at 60 m distance will be about 70dBA.

The noise generating from above activities will affect to labor workers who directly operate machines. devices and workers in t he disctance of 50m from the local devices will be the most affected.

*


Almost construction sites are closely to high density areas and public works, therefore, the effect of the noise is noticeable, especially the centre of city.

The maximum noise levels in public and residential areas must follow the TCVN5949-1998. ~ c c o r d i n ~ to this standard, the contractors will have reasonable construction plans and measures for mitigating the effect of noise to ensure the minimum effects to residential areas.

The effected scope of air pollutants, dust and noise. + The line from dike C of Boc Nguyen reservoir to the water treatment factory is about

800m. + The residential areas consist of 3 communes of Thach Ha district which locate along the road from the water treatment factory to and along from provincial road No 17 to Dai Nai booster pumping station. + Residential areas are along the inner and outer road of the city.

Mitigating measures consist of: - Limit the working near the popular areas or transport materials on the road through the

popular areas. Especially the outer of the city at nigh to limit the noisy effect, the air pollution, and don't make disorder of the life of people.

- Using the transport means according to regulations of decisions No 4134/200l/QD- BGTVT date 05/12/2001 of the transport ministry. Lorry, transport means, construction machine using in the project need to check for the noisy level, uibration and air pollutants levels according to Environmental Vietnam standard 5937-1995.

V.2.6. Kbration by construction machine

Main works of project are excavation of narrow trenches to install the pipeline system, so the soil amount is not much and no need to use heavy devices. Then the vibration level is not much. Devices using mainly is small excavators and manual labor. The device making the vibration is destroying concrete machine when working on the hard surface road. But the vibration level is not much. It can be smaller than the vibration caused by transport means. Morever, works on the hard surface road is not much so this effect is not significant. On the other hand, the main work along two sides of the road does not need to use destroying concrete machine.

Mitigating measures:

Need to care on environmental sanitation, labor safety and welfare of workers during feasibility study phase of the project. To get a good results, the investor will set reasonable working plan, manpower without overlap between working phases, use advanced methods, mechanization in operations and working process at maximum level. Ensure labor sanitation safety and environmental sanitation, specifically application and observation labor safety regulations when set up construction plan such as: working time, working orders. ground urorks orders, reasonable working line; suitable working areas to avoid less moving and obstruction.


- Limit works nearby the residential areas or transport materials on road lines going through high density population, especially in the outer of city at night to limit the effect of noise, the air pollutibn, and disorder in living of people.

V2.7. Affect on the local traffic

Because main part of construction works will happened along the traffic routes so this can not avoid to make the effect on circulation and traffic safety, especially on the center road lines of the city where the larger density and transport flows. The following reasons caused from the transport activities:

+ Assembling materials, constructional wastes will transgress pavement and roadway. + Excavation and filling soil to install pipelines will limit the circulation on the road lines. + Some section pipelines have to set across traffic road lines, so the construction has to be

completed part by part based on road section encroaching at least a half section road. In this case, the transport means can only take turn doing circulation one-way.

Digging a deep trench running along streets will be closely organized to linit the obstruction of transport such as: protective fences, bridge over moat, warning lamps. Popular community and business units will be announced before building.


# b

During construction transports traffic will not be allowed at some fixed time period. Therefore, the contractor will make detail program to make sure the prohibited time is in the short time. This work will be cooperated with traffic polices.

K2.8. Safety

(1) Ability in infecting social diseases

This is happening popularly at construction tents and the populations around. When workers live in less emotional conditions of the family, many workers find to some kind of negative entertainments such as: prostitution, using drugs .... and because their education level and awareness of healthy are low so it is easy for them to get social diseases, HIVIAIDs, and infectious sexual diseases is very high. This is not only happened for workers but aslo infect into local population.

(2) Risk and breakdown

Construction activities usually happen risks and breakdowns which making serious damages for the health of workers. Risks and typical breakdowns in working phase consist of: + Working accidents when operating construction machines, transport means, carry and move heavy things. + Accident when working at deep water areas, huge waves and working in the high areas. + Transport accidents traffic + Epidemic diseases + Risk ca~15ed by explosion material, remained bombs, mines after clearing. + R i s k i i 9 i LCI-ns \\:it11 fail-safety of reservoir and dam.



1-Constructors have responsibility to ensure for workers practiced basically about working safety, prevents occupational diseases that reliable with their responsibility. This is the project working in the long term so that the main constructor should have a staff about safety and healthy who has much experience to be responsible for these works. 2. Set up ambulance stations at workshops to rescue simple accidents or sick before carry them to local hospitals or medical wards 3- Co-ordinate with local government, police to limit, prevent social evils such as: prostitution, drug addiction ... because this is a main cause makes to spread social diseases such as: HJVIAIDs. Simultaneously, combine with propagandize, education method for workers don't join in evils above. 4- Besides the installation of all sanitation devices and facilities in construction areas for worker to control the infectious diseases, the contractors have to take responsibility providing protective labor objects to workers such as: oral masks, boots, gloves, helmet, ... to avoid the affect of noise, dust, vibration affected to their health. For people worked at the places where can happened risks of labor accidents as underground constructions, on the high, in deep water, huge waves, strong wind, need to do safety labor methods according to stipulate of the ministry of labour, wounded sodier and social. For example: 5. Limiting construction time on flooding and raining days and having drainage measures during working process. . 0

VI.2.9. Hygiene I . Effect on the water en~tironrnent

When digging, covering soil is easy eroded, washed out, so that when it is strong rain, mud, soil will be washed out by rain-water and penetrate into agriculture cultivate areas and aquatic cultivate in Thach Lam commune, Thach Tan, Thach Dien ... and the commune in suburb of Hatinh city. The turbidity of water source will increase and affect on the development of rice, farm product and aquatic species. In addition, on the conveying lines go through agriculture cultivated land, erode, wash soil by rain-water also can make extend of sediment for flowing routes with sand and soil such as: drainage waterways, water supply and water drainage systems. Beside, the receipted water gate construction will also make pollution at point the water

source of Boc Nguyen reservoir from actions following: + Dredge mud + Dig and cover soil + Construction works in water. + Operate construction machines Actions above will make the water of reservoir around the construction site have high

turbidity and polluted by organic substances in sewage and oil discharged from machines, construction devices. The effect scope can be predicted about 200-300 m from receipted site with the amount of suspension solid up 20-500 mg/l depend on the distance and the real construction site. However. the situation will not affect on supplying water fol- the plan because the receipted site that built has far away with the present receipted sitc a l7o~11 800 m.


simultaneously the spillway lays between two receipted water sites so the pollutant that discharged in construction process does not move to the present receipted site. Mitigating measures B

- -To ensure enough for material facilities quantity and quality to serve building

workers such as: dining-room. bath-room, healthcare station, toilets. The treatment sewage system with anaerobic method will be installed for toilets to reach the standard VNS TCVN 6772-2000 before flowing out.

- To ensure don't discharge the solid waste, polluted water, oil into water sources, especially into the receipted water site of Boc Nguyen reservoir. The devices used to construction in underwater have to ensure the good situation in operating. Do not oil runs out.

2-Effect by living sewage of workers

The sewage from camps of worker is the main causes environmental pollution. Total average sewage per day of 100 workers are calculated following: a). The living everyday sewage:

- Amount: 10 cubic meters - Collective solid: 20kg - BOD: 4,5 kg - -COD: 8,5 kg - -Oil and fat: 2,O kg. - Total phosphoru;: 0,2 kg. - Total nitrogen: 1,6kg - Bacterium: over 1010 - Parasitic worms: over 105 eggs.

b) Solid waste

Amount: 100 kg, content of 60-70% organic substance and 30-40% other sewages (plastic, paper...).

If sewage above is not collected, managed, and treatment will be contaminated the water sources, polluted underground water and spread diseases. It is not good for tents placed nearly population sites. The waste come from the tent of workers mainly consist of sewage, solid waste that containing organic substance and microorganism causes diseases. The fact: many epidemic diseases happened such as: cholera, dysentery, typhoid etc ... that concern to fly, mosquitoes, insects in the work sites. This is also a reason causes the development of many family of microorganism and when it goes into the water source will spread to the population areas around the locals along the national road NO 17. Many kinds of waste will be collected, transferred and reasonably treated. Investor owner requests contractors signs contacts with the environmental company of Hatinh city to transfer and treat solid waste in the landfill of Hatinh city.


3. Construction wastes.

Solid wastes discarded in consruction process consist of: + Mug, soil in digging, covering process and smooth the space. According to calculating the amount of digging and covering process is about 5.000m3. But, the digging process is equal with the covering process so that can not have redundant soil. The pollution will happen if we don't have strong management method in the digging time. + Thc building waste: soil, sand, granular, concrete, asphalt, broken bricks, mixtured cement, wood for formwork ... the amount redundant need transfer and eliminate about 500m3

Generally, the amount of the solid waste eliminated in construction phase, building, is hard to predict and exactly calculate because of It depend on many factors as: construction method, the natural conditions in the construction areas. The amount of solid waste is not much but it has strongly effect on the environment. + Encroaching the areas without the scope of the project. + Effects on the purpose using land of encroaching areas for example: mixture the top layer land especially agricultural land. + It is the cause making contaminated water source come from rain fall run off that sweep away sand, contaminated substances, simultaneously i t can make sediment that can make effecting drainage system, agricultural waterways.

Some solutions for mitigating of the pollution caused by solid waste. 4

+ Constructing rubbish: formwork, cement paper, iron, steel chips are collected to reuse or recycle. + Sand, soil generated from cover, smooth over surface or from constructing process will be collected to cover the other works. This work has done completely with organizing reasonably in construction because the amount of digging equal the amount of cover. + Contract with the environmental city company Hatinh to transfer rubbish to rubbish. dumps to treat.

4. Effect on the health of community

As above analyzed, negative environmental impacts will directly cause effects not only on the workers at the workshop but also local people, the main reasons are: + Effect caused by polluted air + Effect caused by sewage at workshop + Effect caused by social evils. + Conflict between local people and workers. + Working accidents, hazards and risks (broken downs).

14.2.10. Damaging to the other infrastructures

Some article of infrastructures are affected in digging. covering process, install materials consis of: 1) Electl-ic transfer line 3) Cl )n.int~nication cable.


Generally, construction will not affect too much on the action of two phases above and especially except the cut the electric off and also communication because if it happens it

causes complex results. These are easy damaged works by physical crashes, so that we need to calculate the detail plan and project to have not effects on two works above. 3) Drainage system. 4) Traffic road 5 ) waterways 6) Pavements

While constructing will have to destroy road surface, pavement of some road lines across with pipelines, moreover, while constructing the transfer and distribution water lines will affect on the sewage lines along it, so that i t will affect on the run off of surface water, sewage flowing in these pipelines.

In the design process will calculate to limit maximum these effects, after construction phase surface road and pavement will recover to the first situation. In addition, transfer water pipelines will be designed to limit maximum effects on this sewage system. It is necessary to build a temporary sewage system to ensure have not any effects on the local sewage system.

But, this effect is not much because the construction time is short and is worked by the step by step method it means that after completed this step then move to the next step. If transfer yater systems crosses with the drainage systems , we have to install a temporary drainage system to ensure have not effects too much on the drainage.

VI3. Effect and diminish method in the operation machine.

H.3.1. Polluted water source risk from concerning other sources.

Sources can make the polluted water sources in operation phase.

(1). Breakdown to the reservoir dam

Boc Nguyen reservoir has valley wide about 32km2 with mainly artificial forests and

natural forests. At present, there is a small group people about 50 households they work

farming and forest at the upper reachs about 6km. Base on characteristic of topography and

floral, there are not polluted sources at valley of Boc Nguyen reservoir., after receiping the

managing responsibility, The water supply company Hatinh will link with security, the local

communes to construct protective environment methods for the Reservoir such as: Prevent

fishing, inhibit people live at the valley of the reservoir, affrorest in all areas of the valley of

the reservoir. But, some risks can happen:

+ Using the explosive, toxic chemicals to catch fishes. Patrols of the water supply

company Hatinh wil l increase observation, patrol in the valley of reservoir to discover and

prevent actions above.


+ damage actions, terrorist actions such as: poison the water source by toxic chemicals,

toxic bacteriums, damage works of the reservoir, oil runoff risk. The water supply compan y

Hatinh will co-ordinate closely with security, the local government to buil some project to

increase sercurity ensurement to all the work. When there is the poison action for water

source, the water supply company will stop the supply water and report to appropriate .

authorities to treat.

+ When discovering the development of toxic plants, the water supply company Hatinh

will report for appropriate authorities and co-operate with profesnional organization to

investigate and give a solution to repair.

(2). Breakdown for the water company.

+ Breakdown by leak chemicals out, dispersion chemicals such as: chlorine

+ Penetration of chemicals such as: sodium carbonate, alum, living rubbish into water

source after treat.

Diminish methods are mentioned detail at VI.3.4. Safety chemicals on pages 40-41.

1.1.3.2. Mud and sediment management

At present, There is a tank to collect mud with 50m of width and 70 m of length and 2 m

of depth. It will ensure to contain mud if the capacity of treatment of the tatory is increased to

24.000 m3Iday-night.

When have mud in the tank, Hatinh water supply company will co-operate with Hatinh

environment city to suction pump periodically by special vehicles.

W.3.3. Emitting dust from mud-drying ground

There is not drying-ground because wet mud is moved by Hatinh environment company

to collected areas and it can not emit dust.

1.7.3.4. Emitting dust from uncompleted areas.

The water company has completed all works to operate with the capacity of 24.000

m3lday-night. The project just installs some news devices in workshop.

1.7.3.4. Chemical safety

Chemicals are used in the treatment water consist of: alum, lime and chlorine. Chlorine is

used in pure liquid that can make the highest rish environment. Other chemicals make less

effect on the environment. The concentration of chlorine that is used averagely to sterilize

water is lgim3, in the necessary situation, the concentration can be increased up to 2gim3

The all system usually is checked, install the automatic warming system when the

concentration of chlorine overco~-ne the limited concentration. Chlorine containers are set

order in the tight champers ant1 install the automatic device to put down the chlorine when i t

to leak out.


The factory will regulate where collect rubbish, hygiene period around the factory and

have contract with Environment city company to transport life sewage and treat them at the

isolation areas of the city.

Life sewage will be collected and treated at the underground tank of the system to get the

standard of the B column of VNS 5945-1995 before discharge into the drainage system of the

factory.

The factory will build fence around and have guard on 23 hours per day to ensure security

for the factory as well as ensure without the break in of subversive elements to damage

machines as well as drop toxic chemicals into the water source.

J4.3.7. Forbidding using fertilizer or grazing livestocks

(1). Co-operation with police of Thach Ha district, security force and the local

department to protect the environment of reservoir Such as: to inhibit the settlement of local

people in the valley of reservoir, not arrange any production forms in the valley of reservoir.

(2). Making the water security ring and protec the water supply station

-The water security ring had done at the phase I, such as: no construction, no grazing

cattles, no using fertilizers. 0 . - Hatinh water supply caompany will make a security troop to patrol all areas to ensure

the hygiene condition, safety and monitor the water level and the water quality. When the No2

collecting water gate operates, there is an other patrol station to protect in this site.

J4.3.8.Security for the water company

The water company will be protected by fences system and guards all day.

W.3.9. Safety

- Manuals always attach devices and machines of the factory. Devices and machines are

allways checked and maintained regularly.

- Have warning boards at dangerous sites

- To set up the sign lamps, fire alarm and information system. Checking the leak,

technical pipelines are painted colour according to the standard such as: chlorine lines,

alum lines and lime lines, ... - Designing the light system for the working areas at night

- Having adequate safe devices and prevention i n some emergency breakdowns such as:

oxygen container, water cabin, fire-extinguisher

- Having individual safety such as: labor safe protective clothes, rubber boots, and

safety hanging wires.


- Making the fence to separate dangerous areas such as: power station, the house storing

chlorine. a

- The factory will contract with Hatinh electric company to ensure the electric supply

W.3.10. Sewage

There are not almost nearly any sewage sources that can flow into Boc Nguyen reservoir.

Life sewage comes from the company with the flow amount 3-4m3/day can not contaminate

the water supply. In addition, It is treated before flow into the drainage by the inaerobic

method.

VI.4- Effects and mitigating measures in operating the transport and distribution system

Pipes using to transport and distribute water are made by cast iron that reach the standard

I S 0 2351-1991 K9, it has a corrode layer inner according to the standard I S 0 4179-1985 and

the corrode layer outer reach the standard I S 0 8179 part-1995. But, the transport and

distribution system can make the pollution the water source from some causes following:

+ lnfiltration of contaminating substances into the pipeline when it goes through the

sewage, rubbish dump, and cemetri ... + The pipeline and valve are broken down when it goes through population areas by

people or other activities.

To limit the effect on these pipelines, the projcct will build the sign board at there are

pipelines. There are some acitivities regularly such as: maintain, checking the pipelines sytem

besides there are some methods to repair when proplems are happened.

We need to note the depth of soil layer above the pipeline to protect the pipeline. In

addition, valves are also needed to protect.

Besides, we need to be care about the discharged oil from the power station. The

dischargge oil is collected into tanks to avoid the leak out. Hatinh water supply company will

contract with Hatinh environment company to transport and treat.

K7.3. Monitoring the change of water level of Boc Nguyen reservoir

The collection data of Boc Nguyen reservoir is very important to manage and make the

development production plan afterwards. The data of water level will record everyday attach

with the meteorological data (rainfall, air temperature) this data needs to store in the

document of the company and reports for the resource and environment department

Besides the monitoring the level water, the project will update the change of topography,

geology around Boc Nguyen dam. Moreover, the project will monitor the subsiding of the

construction and data needs to store in the document of the company and reports for the

resource and environment department

V7.4.Monitoring survey land

The mornitoring subsiding will carry out at the receipt water site, the transport raw

water and Dai Nai booster pump station with the time of monitoring 1 time per month in the

first year and the time of monitoring 2 times per month in the year later until1 the work is

stable.

VII. Monitoring framework organization

K7I.l. The responsibility of organization in monitoring raw water quality and after treated s

Hatinh water supply company will have responsibility in monitoring the quality of raw

water quality and treated water. There are some analysic devices in the laboratory of the

company

+ Multilpurpose divice can measure norms: pH, conductivity, temperature, DO, TDS

+ Comparative colour divice and test kit to analyse: Fe, C12 resident, NO3- and some

cations and anions.

But with some norms difficult to analyse such as: As, Pb, herbiside residents need to

analyse by modem devices. So that the project will buy some modem analysis devices to

analyse some norms such as: Mn, Pb, As, N O i , NH4', fecal coli, coliform simultaneously

there are 4 technical workers supported to training about technic analytics. In addition, the

company will or-ordinate with the resource and environment department or The centrer for

technology and environmental treatment in analising difficult samples.

The project will contribute to enhance the ability of the official of state organizations

1). Breakdown dam: The breakdown Boc Nguyen dam can make the disaster for the

local pebple, so that, it is important responsibility to discover the leaking out and erosion.

When discover any dangerous signs, have to announce to evacuate all people in the valley and

organize the emergency force to rescue.

2). Water quality breakdown

If there are contaminated water signs, immediately, cut the system off and announce
