There are more than 7 1400 residents in 10 communes who are gotten advenlives by project.

Area of sub - project locations in Binh Nguyen, Thanh Tan, Vu Thang, Vu Hoa, :Binh Thanh, Binh Dinh (Kien Xuong district), Duy Nhat, Vu Doai, Vu Vinh (Vu Thu district), Bac Hai (Tien Hai district), Thai Binh province are shown in Drawing 01.

3.3 Content of the project a. Household sanitation



Types of latrines proposed in this project are:

This is an improved type of the traditional double vault latrine and has been well widespread in Vietnam and has proven high effectiveness. Ecological latrines have been supported by Department of Preventive Medicine and SANRES Program (Sweden) and many specialized departments have adopted this type of latrine and slightly adapt it to different localities with different conditions. Ecological latrine is appreciated by Ministry o i health and promoted to widespread nationwide. The advantages of ecological latrines are: minimize environmental and water pollution, make use of excreta for agriculture production, low cost, affordable to rural households.

*Ponl-fl~rshl Seepage latrirles,

Seepage latrines have been developed in rural areas of Vietnam since the 1980's in provinces with WATSAN Program. The advantages of this kind of latrines are: clean, no smell, simple treatment, low cost, suitable for areas without drainage system. However, on the .other hand, seepage latrines are only appropriate for areas with plentiful source of water, soil with high absorption capacity, no danger of polluting ground water source. This t,ype of latrine is not suitable in clay areas, low land, shortage of water, and high demand to excreta as fertilizer.

"Septir latrine

Septic latrines originated from Europe and were introduced into Vietnam by the end of the 19th century. This is the best and most advanced type of latrines with outstanding advantages such as: hygiene, no smell, no flies, easy to clean, convenience, privacy. However, this type of latrine is water consuming, and it requires to have drainage system in the residential area, high cost, therefore they can only be affordable to better off households.

- These sanitation facilities should meet the following requirements:

Not disease transmitted

Not pollute the water sources for drinking and domestic purposes

No flies, mosquitoes or other diseases transmitted insects.

Clean. no smell.

No access for animals

- Technical requirement.

Simple techniques are applied for construction, operation and maintenance.

Feces are well treated, no danger of accidents

+ Characteristic of septic facilities.

The components of septic latrines:

- Sitting-plates are constructed by brick or cement, and built up continuous with drain- plates. Drain-plates can be made by cement or tile for easy cleaning. Drain-plates are interconnected with fecal matter pipe and created water-button. Water - button is an



important criteria of septic latrines. Water-buttons can not only be forbidden odour from fecal matter storage component but also forbidden the development of housefly and dung-fly.

- Fecal matter storage tank is as function of storage and pre-sediment component when fecal matter and water after defecating. In this tank, fecal matter will be disintegrated, fat matters will be resurfaced, waste matter will be sediment into bottom, suspend matters will be discharge into L-opposite pipe.

- Vent pipes: vent pipes are connected with septic tank to discharge odour from disintegration, especially CH4, this air is stink and be burned when meeting fire or too hot weather.

Construction conditions:

- Latrine location should be in high area and un-inundation.

- Convenient for old persons and children.

Morlagenlent arld nzainte~zance o f septic' latr.ir~es,for envir-onmental protectio~:

If septic latrines are technically built, fecal matter will be disintegrated, as following:

- Bad odour: discharge through vent pipes

- Fat matters resurface, and created solid film in combining with fibrous matters. Solid film effect to anaerobic development and disintegrate organic matters to water and C 0 2

- Solid matters will be sediment into the bottom and disintegrate to muddy.

Therefore, good self-disintegration need 2 conditions: fecal matters have to soak into water 3- 7 days and fecal matters storage tank have to be close tight. From operation system, using regulations are given:

+ Before using septic latrines, water will be fully filled.

+ Before defecating, pour water into the top of latrines to make fecal matters not sticky

+ After defecating, also pour water or flushing toilet intermediately (about 7-10 1 water)

Some notices:

+ Do not put soup into fecal matters storage tank, because soup will be annihilated anaerobic bacterium.

+ Do not put wrap paper into septic latrines because i t will be blocked up.

+ When septic latrines block up, use soft stick or steel hook for pull waste matters out, and pour water for discharging small tuff into fecal matters storage tank.

+ Put wastebasket in toilet to collect waste paper, and burn waste paper in the end of each afternoon.

+ If can not flush toilet, storage tank for pouring water need to ail-ange in front of the door. It will be advantage for pouring water and also remind person pouring water for latrines.

GI-orlnd water resource: Ground water investigation for hydrogeology map was carried out in

Thai Binh in 1988-1995 by No 58 geological association (Vietnam geological department).

Acorrding to petrography components and aquifer, ground water is highly infected of salt

(Chlorine content > 700mg/l), over acceptable standards. Other hand, ground water quantity

exploration is low, and does not meet the scale of gather water supply system. Hence, using

ground water as water source for gather water supply facilities is not feasible.

demand is quite high now; the residents do not save water because they do not have to pay for

i t . According experience from rural water supply sub-project in stage I and rural water supply

facilities in National Strategy Program, rural household, especially average and poor households, use less clean water because they want to save water monthly fee (average 3m3-

5m3/household/month). Besides, they also continue using existing water resources such as: rainy water for drinking demand or well water for washing and bathing.

5. ENVIRONMENTAL IMPACT ASSESSMENT AND MITIGATION MEASURES

5.1 Positive impacts In general, the overall impacts of the Rural water supply and sanitation infrastructure and health improvement project will be positive and play an important role in improving the rural water supply and sanitation situation in the project area. The key positive impacts are:

Provide centralize water treatment system for local resident. Once the project is in operation, it 'will address the urgent need of local community, that's having access to clean water supply

source. Result of household's water connection survey done with 100% of households in 10 communes show that proportion of household which expect to connect to water supply system

(2008) is high (approximate 80% of total of household).

+Significantly, the sub-projects contribute to improve rural water supply and erivironmental

conditions in 10 communes. Some unhygienic water source will not be used after ,water supply

system and sanitation latrines are completed. It is good to avoid water related diseases such as

skin, digestion .... happening to women and children.

+ Social and economic aspects: Living conditions of people in project area is significantly

improved, creating momentum for other development activities in the locality.

5.2 Potential negative impacts and mitigation measures Beside the aforementioned positive impacts, there are potential negative impacts to natural and

social environment during construction and operation of piped water system though they are

insignificant:

Miti,qation nzens141.e~:

I l le effects by land recovery have been limited from chosing locations of water pumpiilg

station and water treatment plant. The best options of technical design have been considered to

minimize area of recovered land. The proposed area of recovered land in a commune is 2000-

2500m2.

It is showed from fied survey results that interviewed households assumed that coilstruction of

piped water system would not affect their land. If this is the case (impact to their land use,

crops. business,etc.), they accepted lo be compensated by cash.

Technical designs will try to minimize impacts to migration and resettlement. In case, there

ar-e affected households, they will be compensated and supported at reasonable level to ensure the same or even better living standard (Please refer to the Resettlement Plan).

Affected households resulting from land requisition has been informed and participated in site

b. Environmental Impact Assessment during construction phase.


Rual water supply and sanitation sub-project in 09 communes in Thai Binh province (stage 3) --- -

1mptrc.t Assessnzerzt.

Intake and raw water pumping station are located outside dyke, near raw water source.

Therefore, construction of pipeline cross dyke for collecting raw water to water treatment plant

will be influence on safe dyke, special in rainy season. However, because of small pipeline

diameter, short construction time, so that influence on safe dyke can be controlled.

Environmental pollution is caused mainly due to operation of machines and equipment and

vehicle during construction period (excavating, leveling, etc.). Dust and smoke will pollute the

construction site and have direct impact to workers. Residents living 300-400 m from the

project sites and those who live along the road to the project site will also be impacted by the

construction, though these impacts are insignificant.

Dust from landlsand transportation car, construction waste, for this pro-ject, waste IandJstone

are mainly from these activities:

- Construction of water supply system

- Excavating foundation for construction raw water pumping station and WTP

Moving of transportation will be created dust pollution, as given:

- Land in truck wheel will be dropped in succession alleys and wind will transmit dust.

- Land and sand (as dust) will be scatter by transportation means;

- Wheel also c'an create dust in roads when running

- Dust from smoke of transportation means. Dust from these sources above make indisposed for surrounding habitants, because i t easily

transmits in transportation means activities. Hence, dust from these sources always make

indisposed for habitants living along roads which construct water supply pipeline, and WTF.

During construction period, different types of machines, equipments and vehicles are

operating at the same time; this will also cause noise and vibration. However, the: project site

is far away from residential areas, these impacts are minor.

Also during this period, a volume of solid waste, construction materials, oil and lubricants

from vehicles and equipment will also be spread out in the project site. This is not much and

will be collected and treated.

Domestic waste disposed by workers including solid waste and containers, plastic bags,

emptied bottle, etc. these should be collected daily.

Destroy surface road if returning existing surface road is not good: Project will use some

surrounding roads in chosen area for construction. These roads will increase attrition and

broken because of project activities.

Moreover, gathering workers can be influence on social situation, such as: order and security because of different life style, difficult population management for local administration ....

Construction of intake, water treatment facilities can change water quality in point of taking

sample, such as: increase turbidity, suspended solid. Because facilities are near choice raw

water source such as Hong river (Duy Nhat-Vu Doai, Vu Vinh-Vu Thang-Vu Hoa, Binh Than- Binh Dinh-Bac Hai Commune), Tra I-y river (Binh Nguyen-Thanh Tan commune). This is also

main source receive main polluted resource from below activities and worker activities. For

other surface sources: pond. well1 ..., they are also influence on transport materials. However,

because of construction site outside crowed population area, this impact is very small and

short time.

Raw water sources in Thai Binh province are surface water from river crossing to the

commune. These water resources are not only using for agriculture production, but also usong

for navigation. Construction of intake facilities can be influence on boat activities in this area.

Flooding in rainy season, oudour pollution in public latrines need to mitigate when chosi~lg

construction location and proposing technical design

Mitipation measures: When designing and constructing, implementing as technology, construction instruction and

WTP management need to be carried out. Strengthen technical supervisor in constructing

facilities.

a. Applied solutions for feasibility study consultant/ designing :

Facilities location have to be chosen to meet safe distance, dyke protection fence ( far from

20-25m dyke). Time for constructing pipeline cross to dyke should be avoided flooding time,

rainy time and ensure to return facilities accordance with regulations.

Construction fence around construction area, pour water to reducc dust, use model

equipments, construct in suitable time (day time, avoid rest time) to minimize impacts from

dust, noise and waste air.

Impacts such as dust, noise and disposal can be reduced by careful planning and preparation

before carrying out the project such as: installing fence around the project site, water in the

project field so as to reduce dust, use modem equipment to minimize noise, operating

machines during working hours, avoid bed time, etc.

When designing and constructing, Technical regulations, constructed introductions and WTP operation need to implement. Supervision technical aspects for facilities in construction period

need to pay attention.

Pouring water for construction site, stone and sand need to be considered when filling up and

moving out. Materials, equipments storage long time need to be covered, nitigate ti,ai.

Materials, construction equipments are managed, avoid spilling materials when transporting,

covering, constructed storage (if necessary), build fence to protect this area.

When transporting construction material, they need to be cover so as to minimize dust.

Request driver not impose on car whistle and not keep transports blow up too long without any

activities.

Collect solid waste daily and throw at right place. Solid waste like cement package, emptied

bottle, crushed wood and iron, construction materials should be collected, c1,assified for

recycle or reuse in other industry.

Wastewater from the construction including domestic waste water and disposed water from

washing construction materials should be collected and treated for recycle. Mitigation of

discharging wastewater to sewer and river for creating good conditio~ls in construction period

and mitigation the quantity of wastewater and also avoid overflow. Moreover, temporary

collection and treatment of wastewater are applied in construction period.

Using local worker for suitable works will be decreased the change suddenly workers in

construction period. Dissemination of regulation for worker when livings in region, co-

operation with local police manage number of worker, protect construction equipments and

other poverties.

Pay attention to labor safety during construction period. Strictly follow labor safely measures,

ensure clean sanitation and environment protection for the project areas. Workers need to be

well trained on labor safety and equipped with labor devices such as: safety helmets, gloves,

safety belt and appropriate measures should be applied to minimize noise and shaking for the

surrounding areas.

Develop instruction and signal boards at the site to warn people and minimize accidents.

Machines, equipments and vehicles need to be checked up regularly.

In case the construction site is near to the dyke, i t is important to strictly obey the dyke

protection regulations. The advised safety distance from the dyke to construction site is about 25m, if direct impacts to the dyke systems, local authorities should be informed and agreements should be reached.

Provide instruments and water quality testing equipment to do the on-site test with quick results to timely identify problems and solution for better operalion and maintenance of the system; train on awareness rising for managers and operators.

Applied methods of fighting fire, as following:

- %rage burning materials in location far from burning sources or can be burned in large area: far from doors, fan! .

- Fighting fire equipments need to check annually

- Put easy bum sign and avoid sign such as: no smoking, no mobile phone'

- Give exercise for worked about fighting fire

Avoid accidents because uf chemical and non-resistant or oxygen elements: non-resistant and

other poison chemical have to be controlled as ease burning materials. However, chemical also

can be danger if mixing with other chemicals. Therefore, management chemical methods

should be applied.

- Keep chemical separate and far from easy burning materials

- Chemical components have to storage in safe rank, chemical room has to fully \ventilate

- Workers have to use fully protect clothes such as: coats, hats, shoes' .

- WTP has to have sink, shower use when operating

Local government organizes clean and green environment movements regularly including protection of water supply source, proper use, collection and treatment of excreta, waste and

wastewater.

During operation period, people's comments and opinion about the water supply system need

to be taken into consideration and resolved timely.

6. ENVIRONMENTAL MANAGEMENT PLAN According to the Vietnamese regulation on Enviror~mental Protection and the World Bank's Environmental policies, the winning Contractors (for construction and operation) together with the Prqject Management Unit and other related agencies have to carry out the Environmental Managcment Plan.

The objective of Environmental management plan is to provide guidelines on the Project's

environmental issues so as to ensure that environment related issues would be well dealt with.

Environmental Management Plan includes monitoring and reporting program for

enviro~imental impacts mitigation: implementation organization and countermeasures in case of emergencies.

6.1 Implementation Organization Environmental Management Plan (EMP) is prepared that base on regulations of Viet Kam and Worldbank. Environmental Management Plan will be implemented by the followirig agencies:

-- --

Environmental protection commitment SO

Rual water supply and sanitation sub-project in 09 communes in Thai Binh province (stage 3) p--pppp

The Project Management Unit will be in collaboration with relevant agencies and other

functional bodies at Provincial, District and Commune level to implement the EMP. The

Project Management Unit will nominate a full time environmental expert to monitor, manage

and carry out the assigned tasks.

Winning contractors for construction and operation are responsible to monitor environmental quality in different project periods to strictly follow the mitigation measures, agreements and

commitment as stated in the assigned contract.

Communities in the project areas are participated actively in project activities including

environmental management plan.

There will also have the involvement of the Environmental specialists who are responsible for

capacity building and training for organizations and individuals who will involve in the

implementation of the Environmental Management Plan.

6.2 Environmental monitoring and reporting The purpose of the Environmental Monitoring and Reporting of the sub-project on Rural

Water Supply and Sanitation is to regularly collect information on environmental impacts

while implementing the project, at the same time to timely discover negative impacts so as to

have prevention and mitigation measures to minimize pollution. Moreover, Environmental

Monitoring also aims to closely control the environmental quality to ensure safe operation of

the Project.

Content of environmental management plan includes environmental impacts monitoring and

mitigation measure implementation.

Environmental impacts monitoring is to identify the impacts arising at all project sites.

To monitor the mitigation measure implementation is to assess how effective proposed

mitigation measures in EMP

a. Project Preparation period Land compensation and Site clearance activities are monitored and assessed perioclically (once

a month or every 3 months) at recovered areas for treatment plant, pumping station and

pipeline network. The Project Management Unit will be in cooperation with functional body at

local level for disseminating project information to resident, monitoring environment and

reporting. Related agencies should update information about the project to solve petitions timely.

b. Corzstruction period It is expected that i l takes about 8 to 12 months for second stage project construclion in Thai

Binh. Monitoring criteria include:

Dust and noise arising during construction period at the Project site will be periodically

checked at the treatment plants, the transmission pipelines and distribution pipelines every

there months.

Solid waste from construction site and human waste from workers need to be collected and safely treated.

----



Regularly check the application of labor safety measures during construction period to identify

and prevent risks.

c. Management and operation period Noise caused by operating schemes is controlled and checked once every 6 months.

Raw water and treated water will be tested monthly (for basic parameters of Group A) and

annually (for basic parameters of Group B) based on the standard No. 1329/2002/BYT/QD of

MOH. Sample raw water for testing is taken before water is taken into treatment plant. Sample

treated water for testing is taken from households' tap.

Waste during operation period including washing water and sedimentation from treatment

plants have to be treated and managed. These factors need to be checked quarterly or every 6 months.

Monthly check and identify urgent solutions for treatment plants, chemical house,

transmission pipe lines, and distribution pipe lines in case there are problems on chemical

leakage, water source, etc.

Environmental monitoring reports during operation period is prepared by the water supply

Operators and submitted to local environment management agencies annually or upon request

at specific period.

likely that this may have certain impact to the river's dyke system 1 crossing the commune

Workers may cause social and isecurity impacts in local area I

In case the construction site is near to the dyke, it is important to strictly obey the dyke protection regulations. The advised safety distance from the dyke to construction site is about 25m, if direct impacts to the dyke systems, local authorities should be informed and agreements should be reached.

These impacts should be limited right at the beginning when selecting the water supply source, project sites

Using local worker for suitable works

( Dissemination of regulation for worker when livings in region, co-operation with local police manage number of worker, protect construction equipments and other poverties.

7. ENVIRONMENTAL CONSULTA'TION Local authorities, relevant agencies and com~nunity participated in different stage of the

Project from preparing environmental impact assessment to environmental management and

monitoring.

Method of information dissemination and community consultation could be included: Rapid participation assessment, HH visiting, public meeting and socio-economic survey.

Right at the beginning during project preparation phase, local autiiori:lcs ;~nd ie-.Jc;.s a~ different levels in the project province have been informed about the project, it's objectives

and activities. Department of Natural Resource and Environment are consulted and they have

actively participated in discussions on various activities related to environment in their

localities. The feedbacks on advantages and disadvantages of the project and the proposed

mitigation by local authority as well as environmental impacts have been considered to choose

technical solution.

Local residents in communes also involved in environmental impact assessment throl~gh community meetings when they are informed about the project, project objectives, project

activities, positive and potential negative environmental impacts to their commune. People's

comments and opinions from these meetings have been taken into consideration and

incorporated into environment reports.

Minutes of community meetings with feedback on environment issues and mitigation from

Community consultation are attached as annex of this report. Community opinions focus on:

- Effected agricultural products by land acquisition in preparation and construction

- Traffic is at a standstill

- Impact from noise and air pollution in construction

- Chemical leakage when operation and transportation.

All environment impact and mitigation measure given in this report got local authority and

community's agreement. They are ready to participate in environment monitoring activities in different project periods.

Thc Environmental protection commitment is finalized after corninunity meeting. All

environment impacts have given by community that aloes mention in this report and to be

limited by mitigation measure in preparation, construction and operation project. Environmental protection commitment is one of the pre-conditions for project appr;lisal.
