I. INTRODUCTION

Background

1. The Local Government Enhancement Sector Project (LGESP) was approved by ADB

on 29 September 2012 with an amount of $59 million equivalent from ADB’s Special Fund Resources. The loan became effective on 29 November 2011 and the loan closing date is 31

December 2016. Ministry of Provincial Council and Local Government (MPCLG) is the

executing agency, and subproject coordination unit (SPCU) is established in each provincial

council (total seven) to supervise and coordinate and project implementation. LGESP has

been supporting local infrastructure improvement and basic service delivery in less-developed

areas in seven provinces (excluding the Northern and Eastern Provinces), based on a bottom-

up, demand-driven approach. The additional financing is required to scale up a well-

performing project. It includes (i) improvement of water supply systems in areas affected by

chronic kidney diseases (CKD); (ii) improvement of local infrastructure and basic services

delivery; and (iii) advancing policy reform of local government and strengthening their capacity.

2. Naththandiya PS which was established in 1988 is situated in the Puttalam District in

the North Western Province of Sri Lanka. It is located East of Puttalam in Puttalam District of

North West Province and about 80 km away north east from Colombo (via Colombo Kandy

HW) and 20km away from provincial capital Kurunegala. The PS consists of 94 GN divisions,

has a population of 71,693 and is of an area of 71.94 sq.km.

3. This subproject area is primarily an agricultural area and safe drinking water is in short

supply. The drinking water requirement of the community is fulfilled through various means

and sources. Safe drinking water has been identified as a priority need of the people in the

area through public consultation meetings.

4. A community consultation meeting was held at the community hall at Mailawa in 2016

to discuss the projects to be implemented through ‘PuraNeguma’ programme. Secretary, officers of the PS, officers of the PuraNeguma and the general public attended this meeting.

The consent of the majority of those presents at the meeting has been given for balance

improvements of this sub project. As the availability of funds has considered the possibility of

carrying out both identified improvements which is also a priority request, then decided to

undertake a water supply scheme for the village of Mailawa, Kruswatte and Panangoda area.

The two projects proposed Mailawa, Kruswatte and Panangoda will be maintained by PS after

completion.

5. This due diligence report is prepared as the sub project selection was based on the

community consultation and participation criteria .Panangoda and Mailawa, Kuruswatte water

improvement project was selected as a priority sub project to be financed with the LGESP

funded by Asian Development Bank.

6. The Panangoda Kuruswatte water supply sub project will be implemented in the

Panangoda and Mailawa GN divisions of the Mahawewa and Naththandiya Divisional

Secretariats respectively. The people living there use well water for drinking and other

3

domestic purposes and there is severe shortage water particularly in the dry period (June to

October) during which times the quality becomes inferior. There is no drinking water supply

system provided to this community who are to be served by the subproject.

7. Through a consultation and participation process carried out with the community and

the other stake holders, and based on the sub project selection criteria, priority order of the

requirements of the public and the financial capacity of the PS to carry out the operation and

maintenance of the asset to be created by the funding, construction of a water supply project

in Panangoda and Kuruswatte to provide a better and efficient service to the community was

recommended for funding.

8. Adding more convenience for the people in the area, fulfilment of clean and safe

drinking water, supply of water continuously for the people living in the area are expected as

benefits through this water supply project.

9. The proposed scheme for Kuruswatte is expected to include the existing tube well, an

overhead water tank, filter house, and package plant and chlorination system for Kuruswatte

in PS owned land and transmission line and distribution network. For Panangoda it is

expected to include the existing tube well, an overhead tank and chlorination system in PS

owned land and transmission line and distribution network. Analyse of distribution network of

WSS was done using hydraulic modelling software of ‘EPANET’.

10. The numbers of beneficiary households in every area have been determined. Water

source is available to suit the requirements of the people and PS, giving due consideration to

the reliability and long term operating and maintaining capability of the organization that is

going to operate the scheme. Distribution network of the water supply scheme consists of pipe

lines of diameters 110, 90 and 63 mm. Total length of pipe lines in the network is about 6.5

km for Panangoda and 3.5 km for Kuruswatte. Initially, water will be issued to 196 families for

Panangoda and 75 families for Kuruswatte. Total Cost Estimate is Rs.33.10 Mn.

Objective of the Subproject

11. The objective this sub project is to supply clean and safe drinking water to people in the

Panangoda , Mailawa GN divisions of the Mahawewa and Naththandiya Divisional

Secretariats respectively, who use well water for drinking and other domestic purposes by

constructing an overhead water tank, filter house, package plant , transmission line and

distribution network in Kuruswatte and overhead tank ,transmission line and distribution

network in Panangoda ..

Categorization and Justification

12 Based on results of the Rapid Environmental Assessment ( Appendix 2), ADB SPS 2009,

and EARF the subproject is classified as environmental category C, i.e the subproject is

judged to be unlikely to have adverse environmental impacts but would have some

construction related impacts which could be mitigated/minimized to acceptable level by

adopting mitigation measures. DDR Environment report is prepared accordingly.

II. PROJECT DESCRIPTION

Present Location and Environmental Status

13. The Panangoda drinking water supply scheme’s tube well is located at 7°27'06.9"N

79°54'33.0"E and its overhead tank is located at 7°27'05.3"N and 79°54'29.2"E .Mailawa,

Kuruswatte drinking water supply scheme’s tube well is located at 7°25'12.6"N 79°52'56.9"E

and its overhead tank is located at 7°24'53.6"N 79°52'58.8"E.

14. Naththandiya PS is situated in the Puttalam District in the North Western Province of

Sri Lanka. The PS consists of 94 GN divisions, has a population of 71,693 and is of an area

of 71.94 sq.km. The elevation of the PS is 36 m from MSL.It is located about 80 km away north

east from Colombo (via Colombo Kandy HW) and 20 km away from provincial capital

Kurunegala. The boundaries of the PS are Chilaw PS from North, Indian Ocean from West,

Wennappuwa PS from South and Kurunegala District from East.

15. Naththandiya PS is a fast developing city in the North Western Province, Sri Lanka

with a well-connected road and railway network. It is situated between Puttalam and Chilaw

(in the A3 Puttalam to Peliyagoda road) town. It is one of the most populated residential parts

of the division with over 70,000 people including all religions - Buddhist, Hindu, Muslims,

Christian, living together with prosperity and harmony.

16. The main economic activity of the area is agriculture with coconut being the main

cultivations. Majority of the community depends on agriculture as their livelihood, where most

of them are engaged in paddy cultivation.

17. The proposed site for the Panangoda drinking water supply scheme is located in the

Panangoda GN division of Mahawewa DS division. The proposed land is owned by the

Pradeshoya Sabah, Naththandiya . Existing tube well (water extraction point) and overhead

tank are situated in the same land at about 130m distance apart. The proposed sites for

Mailawa, Kuruswatte scheme is also owned by the Pradeshiya Sabah, Naththandiya. Tube

well of Kuruswatte drinking water supply scheme is located in about 02 perch land while its

overhead tank will be constructed in a separate land with an area of 30 perches which is

located at about ½ km away.

18. Naththandiya falls within the low country intermediate zone, with an average annual

rainfall between 1750 - 2500 mm. The rainfall to the area is experienced in two folds. It is

around 155 mm in the months of April, May, June, October and November and reduces to

around 44 mm in the other months of the year. The rainfall is mainly affected by North East

5

and South West Monsoonal rains and inter monsoonal rains. The region receives an annual

average precipitation of 2064.5mm (2015). However, significant deviations in the rainfall

pattern had not been observed. The average annual temperature in the region is hot as 28.1 0C (2015). Major deviations had not been observed for the past 5 years.

19. A significant percentage of the soil in the area is a sandy soil. In addition, low humicgley

soil, Regosols on old red and yellow sand, Red Yellow Podzolic soils with soft and hard laterite

are also present.The terrain could be categorized mainly into three types, rolling, undulating

and flat. Water streams, rivers and even tributaries could be observed.

20. There are no environmentally sensitive areas such as reserved forests, protected water bodies or water channels within or in the vicinity of the project implementation area. The subproject site is not adjacent or within the area of close proximity to any environmentally protected area Eg. (i) area administered by the Department of Wild Life Conservation, (ii) Department of Coast Conservation & Coastal Resources Management, Department of Forests, (iii) the area declared as low lying and flood protection under the SLLRDC Act, and (iv) No archeologically protected monument is located in close proximity. There are areas like home gardens, paddy fields, small irrigation canals and natural water ways to receive surface drainage generated from rains. 21. The existing legislation and standards applicable for the designing projects in Sri Lanka

are mainly based on the National Environmental Act (NEA). According to the provisions under

the NEA No 47 of 1980 and the regulation on EIA which has been gazetted in 1993, this sub

project does not require an EIA or IEE prior to implementation of the sub project. As per ADB

SPS 2009 and EARF of the project, Rapid Environmental Assessment (REA) was carried out

to identify environment issues. This project is a water supply project and related environmental

impacts have been identified through this process. Accordingly developed EMP and EMoP

are shown in Appendix 3.

22. All quarry operations and mining operations connected with the project will require a valid

license issued by the Geological Survey and Mines Bureau (GSMB). All the effluents and/or

emissions shall be in compliance with the standards recommended by the National

Environmental Act (NEA).

Proposed Work

23. The Panangoda drinking water supply scheme is located in the Panangoda GN division

of Mahawewa DS division. Mailawa, Kuruswatte drinking water scheme is located in the

Mailawa GN Division of the Naththandiya DS division. The source of water for the schemes

are from two existing tube wells located at Panangoda and Kuruswatte. The Google map and

the photos annexed as Appendix 1 herewith which clearly shows the details of the subproject

areas and drawings of the pipe lines.

24. In the proposed land of Panangoda where the pump control room and overhead tank

are to be built, a community building managed by Pradhashiya Sabah is available. The water

extraction point (existing tube well) is also located in this land about 200m away.

25. There are no environmentally sensitive areas located within or adjacent to project

areas. Mainly, the land areas surrounding the location are coconut plantations and residences.

6

Land of the Sub Project area is generally flat. There are no prominent towns within sub project

area except for Naththandiya town. Elevation of the sub project area is approximately 36

meters above Mean Sea Level. The water quality in the tube well of Kruswatte, Mailawa is

not within the level of drinking water quality standards and therefore a Package plant will be

introduced to treat the raw water to drinking water quality standards. Water quality of

Panagoda tube well is within the level of drinking water quality. Water quality reports are given

in Appendix 4.

26. Land where the overhead water tank of Kuruswatte scheme is to be built, is located

01km away from the existing tube well. Overhead tank will be built in the highest elevation in

the area. A few trees such as Ketakala ,Kenda and Margosa are available in this land.

Yatikalana Sri Dhamma Vijayaramaya is the only religious place located in the surrounding

area.

28. The technical design is done in close coordination with the safeguard team of SPCU and

Design and Supervision Consultants. The due diligence process was conducted for the

proposed water supply project accordingly Local Government Enhancement Sector Project

EARF and ADB SPS 2009. Upon project implementation, the Safeguards Specialist at PMU

and the Safeguards Manager at SPCU will undertake a review of this due diligence, prepare

a confirmation report documenting any modifications for this sub-project and submit to ADB;

and receive a “no objection” confirmation from ADB prior to start of construction.

29. All technical designs and provisions are in accordance to National Standards

(ICTAD/CIDA and BS specifications) and will be constructed in close coordination with

Safeguard Team of SPCU and Design and Supervision Consultants. Related supplementary

drawings have been added in Appendix 1.

30. The environmental due diligence process has been conducted for the proposed

construction of the water supply project. This report describes details of environmental

safeguards, potential impacts, mitigation methods and monitoring parameters etc.

Safeguards staff of the SPCU, DSC, PMU and PMC are involved in developing this

environmental due diligence report in order to obtain clearances and approval from ADB prior

to initiation of any construction activity.

III. POSSIBLE IMPACTS& MITIGATION

31. Environmental screening was carried out as a part of this environmental due diligence

exercise. Rapid Environmental Assessment (Appendix2) reveals that there are some

environmental impacts and mitigation is possible during construction time and issues are

possible with the preparation and execution of the Environmental Management Plan

Environmental Management Monitoring Plan attached in this DDR .

32. The main objectives of the Rapid Environmental Assessment and the due diligence

screening are to identify the direct and indirect impacts on the physical, biological and social

or cultural heritage environment. Under the component of human risk, community/

occupational health and safety associated with the proposed construction and operations of

the subproject, particularly issues related to accident prevention, dangerous working

conditions, environment pollution and soil/ground…etc. are identified.

33. However, in consideration to the neighboring areas and the population distribution,

findings of some anticipated impacts due to the subproject activities and their management

measures can be discussed as follows;

I. Land use – There are no natural forest patches or natural streams running across the

project area. The road section selected for pipe laying has different land uses mixed with

natural environment at different locations. Along this particular road section, one can

observe quite a lot of home gardens in different scale. Livestock farming is also a popular

livelihood in this area. However, the main economic activity of the area is agriculture

specially with coconut cultivations. Majority of the community depends on agriculture as

their livelihood, where most of them are engaged in paddy cultivation. Less than half the

8

agricultural work is in paddy cultivation and most others in agricultural employment are

involved in cultivation of fruit crops and vegetables.

II. Ambient Air Quality – Construction activities will involve movement of vehicles carrying

construction material…etc. This will result in limited fugitive emissions on site. Spraying

of water during construction will reduce the emissions of dust fall to a great extent.

However, proper coverage shall be provided at the boundary area of the subproject site

as an environmental and safety precautionary measure before commencing the

activities.

III. Ambient Noise levels and traffic – During the construction phase, the sources of noise

pollution will primarily be limited to use of machineries and movement of vehicles

transporting construction materials and equipment to the site.

IV. Movement of traffic– The additional increase in construction related vehicles is of

concern during peak traffic hours, particularly office hours, school opening and closing

times. Its advisable to consider road safety such peak traffic hours to make sure no

accidents.

V. Waste collection and disposal facility- A system of appropriate collection (of sorted

waste) and disposal of bio-degradable and non-biodegradable solid and liquid waste will

be implemented in the subproject site. As per contract, any unusable waste shall be

disposed by the contractor to a site selected and informed by the Engineer, but with prior

approval from the Employer. Solid waste produced by the work force should be properly

disposed in agreement with the PS. Solid waste and debris generated from construction

activities should not be disposed on the sides of the road or left after construction works

is complete. Locations of sites for disposal of such waste will be selected by the

contractor in consultation with the PS. Garbage bins should be provided at all times and

they should be collected by the PS constantly.

VI. Storage of materials – Due care and separate storage shall be arranged particularly for

storage of construction materials, tools and equipment, plumbing and electrical

items...etc.

VII. Health & Safety of workers- During land clearing and construction emission of dust is

inevitable. Contractor shall distribute dusk masks to all workers to ensure protection from

dust. Dispersion of dust would be curtailed by regular watering of working areas. In

addition personal protection equipment such as helmets, gumboots, hand gloves, safety

jackets and safety belts shall be geared up accordingly. Health & safety awareness will

be provided to contractor’s workers.

VIII. Demarcation of working area, prior planning for specific work area and

dissemination of information through signage - Signage will be placed at specific

locations, which will show type and period of work. Also, work area will be demarcated

before starting of the work.

9

IX. Co-ordination and co-operation - Considered necessary among the staff and workers

particularly on following aspects:

Since the work has been proposed to be carried out in a rural area the contractor

shall ensure that the regular day today functioning of the area are not affected

during the construction work.

The contractor shall execute the work with prior approval of the work sequence

from the engineer.

During execution of work, materials will not be stacked in common areas and

utmost care shall be taken by the contractor to avoid any inconvenience due to

improper stacking of materials. If for any unavoidable situation, the materials

have to be stacked for a short time, prior permission from engineer shall be

obtained.

IV .GRIEVANCE REDRESS MECHANISM 34. A project-specific grievance redress mechanism (GRM) has been established to

receive, evaluate, and facilitate the resolution of affected person’s concerns, complaints and grievances about the social and environmental performance of LGESP. The GRM of the

project has been prepared and accepted by ADB and disclosed in the project website. The

GRM chart providing information on receipt of complaints and levels of redressal is displayed

in all subproject sites, local authorities’ offices, SPCU offices and other important places. The SPCU records all grievances received and address them on priority. To date all grievances

are addressed at the stage of first tier.

35. The GRM aims to provide a time-bound and transparent mechanism to voice and

resolve social and environmental concerns linked to the project. The GRM is project-specific

and not intended to bypass the government’s own redress process; rather it is intended to address affected people's concerns and complaints promptly, making it readily accessible to

all segments of the affected people and is scaled to the risks and impacts of the project.

36. The PMU and SPCUs will make the public aware of the GRM through public

awareness campaigns. Grievances can be filed in writing using the Complaint Register and

Complaint Forms or by phone with any member of the PMU or SPCU. The contact details of

the respective SPCUs will serve as a main avenue for complaints and will be publicized

through display on notice boards outside their offices and at construction sites. The safeguard

documents made available to the public in an accessible version will include information on

the GRM and will be widely disseminated throughout the corridor by the safeguards officers

in the PMU and SPCUs.

37. First tier of GRM. The SPCU is the first tier of GRM which offers the fastest and most

accessible mechanism for resolution of grievances. The Safeguards Manager – Social and

Gender in the SPCU will be designated as the key officer for grievance redress. Resolution of

complaints will be done at the earliest. Investigation of grievances will involve site visits and

10

consultations with relevant parties (e.g., affected persons, contractors, traffic police, etc.). The

Community Development Officer of the local authority or in the absence of Community

Development Officer, any officer who is given the responsibility of this, would coordinate with

the safeguards and gender manager of SPCU in redressing the grievances. Grievances will

be documented and personal details (name, address, date of complaint, etc.) will be included

unless anonymity is requested. A tracking number will be assigned for each grievance,

including the following elements:

• Complaint Register and Complaint Forms (including the description of the

grievance) with an acknowledgement of receipt given to the complainant when

the complaint is registered;

• Grievance monitoring sheet with actions taken (investigation, corrective

measures); and

• Closure sheet (Result of Grievance Redressal), one copy of which will be

handed to the complainant after he/she has agreed to the resolution and

signed-off.

The updated register of grievances and complaints will be available to the public at the SPCU

office, construction sites, and other key public offices. Shall the grievance remain unresolved

it will be escalated to the second tier.

38. Second Tier of GRM. The Social Safeguards and Gender Manager of SPCU will

activate the second tier of GRM1 by referring the unresolved issue (with written

documentation), The Grievance Redress Committee (GRC) will be established before

commencement of site works. A hearing will be called with the GRC, if necessary, where the

affected person can present his and/or her concern or issues. The process will facilitate

resolution through mediation. This local GRC will meet as necessary when there are

grievances to be addressed. The local GRC will suggest corrective measures at the field level

and assign clear responsibilities for implementing its decision at the earliest. The contractor

will have observer status on GRC. If unsatisfied with the decision, the existence of the GRC

will not impede the complainant’s access to the Government’s judicial or administrative remedies.

39. The safeguards and gender manager of SPCUs will be responsible for processing and

placing all papers before the GRC, maintaining database of complaints, recording decisions,

issuing minutes of the meetings and monitoring to see that formal orders are issued and the

decisions carried out.

40. Third tier of GRM. In the event that a grievance cannot be resolved directly by the

SPCUs (first tier) or GRC (second tier), the affected person can seek redress through third tier

1 The GRC will consist of the following persons (i) Commissioner of Local Government of the Province as Chairman, (ii) Divisional Secretary of the area; (iii) Chairman of the respective pradeshiya sabha; (iv) representative of nongovernment organizations and/or community based organizations working in the area as nominated by CLG; (v) Member of clergy of pradeshiya saba area; (vi) Chairman of Samathamandal; (vii) GramaNiladhari of the area; (vii) Social Safeguard and gender Manager - as Member Secretary of the GRC. The functions of the local GRC are as follows: (i) resolve problems quickly and provide support to affected persons arising from various issues including environmental and social issues.

11

at the central level. The third tier - Central Grievance Redressal Committee consists of (i)

Project Director as Chairman; and (ii) Legal Officer of MPCLG as member and Social

Safeguard and Gender Officer of PMU as Member Secretary.

41. In case the grievance is not solved at this level, then the complainant can refer the

same to the court of law.

42. The detailed GRM is hosted in the project website. The graphical representation of the

GRM is given at Fig 1 below.

43. The safeguard monitoring reports will include the following aspects pertaining to

progress on grievances: (i) number of cases registered with the GRC, level of jurisdiction (first,

second and third tiers), number of hearings held, decisions made, and the status of pending

cases; and (ii) lists of cases in process and already decided upon may be prepared with details

such as name, ID with unique serial number, date of notice, date of application, date of

hearing, decisions, remarks, actions taken to resolve issues, and status of grievance (i.e.

open, closed, pending).

44. All costs involved in resolving the complaints (meetings, consultations, communication

and reporting and/or information dissemination) will be borne by the executing agency.

V. ENVIRONMENT MANAGEMENT PLAN (EMP) AND ENVIRONMENTAL MONITORING PLAN(EMOP)

45. Though the impacts are mostly construction related the contractors have to follow an

Environment Management Plan during construction phase of the project to mitigate those

impacts. The Environmental Management Plan(EMP) and Environmental Monitoring Plan

(EMoP)are attached vide Appendix 3. The Contractor will be required to submit

Environmental Management Action Plan ( EMAP) including the time -frame and the allocated

budget. EMAP should be prepared based on the environmental issues, migratory measures

identified in the EMP and EMoP.

VI. CONCLUSIONS AND RECOMMENDATIONS

46. The negative environmental impacts arising due to execution of the proposed water

supply scheme are minor and negligible as compared to the long term Socio-economic and

health benefits to be delivered to people of the project area. Negative impacts can be mitigated

to standard levels without difficulty through proper engineering design and the incorporation

or application of recommended mitigation measures and procedures as per EMP.

47. It is recommended that (i) DDR be made part of the bid and contract documents to

ensure mitigation measures are appropriately budgeted and legally binding to the contractors;

(ii) monitor diligently contractor/s EMP implementation by PMU, SPCU and consultants on

EMP implementation by contractors.

48. Conclusion. The subproject will not cause adverse environmental problems during

preconstruction, construction and operational stages since the identified potential adverse

impacts during environmental assessment study are manageable by implementing proposed

mitigation measures at right time and monitored through a comprehensive environment

monitoring plan as described in this DDR report. Therefore, an IEE will not be required.

B. POTENTIAL ENVIRONMENTAL IMPACTS

Will the project cause…

Degradation of environment due to

clearing of area/ removal of vegetation

for cutting trenches.

No trees or shrub vegetation found in the pipeline trace. Already a disturbed area.

Pollution of raw water supply from

upstream wastewater discharge from

communities, industries, agriculture,

and soil erosion runoff?

Not applicable.

Impairment of historical/cultural

monuments/areas and loss/damage to

these sites?

Not applicable. There are no historical/cultural monuments/areas within or adjacent to subproject sites.

16

Screening questions Yes No Remarks

Hazard of land subsidence caused by

excessive ground water pumping?

Not applicable.

Social conflicts arising from

displacement of communities?

No displacements required. Subproject sites are within ROWs of public roads

Conflicts in abstraction of raw water

for water supply with other beneficial

water uses for surface and ground

waters?

Water from tube wells will be extracted below the safe extraction level as recommended by Water Resource Board(WRB) so that no conflict will arise with other beneficiaries using ground water in the surrounding area.

Unsatisfactory raw water supply (e.g.

excessive pathogens or mineral

constituents)?

Raw water is purified in a package plant where Fe and Mn will be removed and chlorination is done

Delivery of unsafe water to distribution

system?

The distributed water will be treated and ensured to comply with the National Drinking Water Quality Standards.

Inadequate protection of intake works

or wells, leading to pollution of water

supply?

Not applicable. Well-protected water sump has been established.

Over pumping of ground water,

leading to salinization and ground

subsidence?

Not applicable.

Excessive algal growth in storage

reservoir?

The water is chlorinated and there is no chance for algal growth

Increase in production of sewage

beyond capabilities of community

facilities?

Not anticipated. Community is having good sanitation facilities.

Disposal of sludge from water

treatment plants?

Sludge will be removed as specified in the EMP.

Inadequate buffer zone around

pumping and treatment plants to

alleviate noise and other possible

nuisances and protect facilities?

Residences are located away from the WTP.

Impairments associated with

transmission lines and access roads?

Not applicable.

Health hazards arising from

inadequate design of facilities for

receiving, storing, and handling of

chlorine and other hazardous

chemicals.

Well-designed office and warehouse have been built at the site of WTP.

Health and safety hazards to workers

from handling and management of

chlorine used for disinfection, other

contaminants, and biological and

physical hazards during project

construction and operation?

Well protected hazard management measures are in place at the WTP

17


Dislocation or involuntary resettlement

of people?

No involuntary resettlement impacts envisioned. Lands for the subproject are government-owned

Disproportionate impacts on the poor,

women and children, indigenous

peoples or other vulnerable groups?

Not anticipated. The contractor will be encouraged to hire local workers from the local labor force.

Noise and dust from construction

activities?

Anticipated during construction activities. Temporary increase in noise level and dusts may be caused by excavation equipment, and the transportation of equipment, materials, and people. The impacts are negative but short-term and site-specific within a relatively small area. They are also reversible through mitigation measures. Good construction practices will mitigate noise and dust, and will be specified in the EMP.

Increased road traffic due to

interference of construction activities?

Traffic management measures will be adopted along the construction sites with proper signage and traffic plans.

Continuing soil erosion/silt runoff from

construction operations?

Due to excavation and run-off from stockpiled materials. The impacts are negative but short-term and site-specific and reversible through mitigation measures. Good construction practices will mitigate soil erosion and silt runoff and will be specified in the EMP.

Delivery of unsafe water due to poor

O&M treatment processes (especially

mud accumulations in filters) and

inadequate chlorination due to lack of

adequate monitoring of chlorine

residuals in distribution systems?

Back wash operations will be adopted for every 24 hours and mud and other impurities will be removed from the sedimentation and filtration beds. Good operational and maintenance practices will minimize pollutants discharged and will be specified in the EMP.

Delivery of water to distribution

system, which is corrosive due to

inadequate attention to feeding of

corrective chemicals?

The project will include development of O&M manuals to ensure facilities are kept in working condition, including checking and maintenance of distribution network. Any distributed water must comply with the National Drinking Water Quality Standards.

Accidental leakage of chlorine gas? Not applicable as protective measures have been implemented at IWTP

Excessive abstraction of water

affecting downstream water users?

Not applicable.

Competing uses of water?

Increased sewage flow due to

increased water supply

Not applicable. Households have adequate sanitation facilities

Increased volume of sewage

(wastewater from cooking and

washing) and sludge from wastewater

treatment plant

18


Large population influx during project

construction and operation that causes

increased burden on social

infrastructure and services (such as

water supply and sanitation systems)?

Improved management systems through capacity building and institutional development will ensure reduced burden on services and infrastructure.

Social conflicts if workers from other

regions or countries are hired?

Priority in employment will be given to local residents.

Risks to community health and safety

due to the transport, storage, and use

and/or disposal of materials such as

explosives, fuel and other chemicals

during operation and construction?

Not applicable. Construction will not involve use of explosives and chemicals during the construction phase.

Community safety risks due to both

accidental and natural hazards,

especially where the structural

elements or components of the project

are accessible to members of the

affected community or where their

failure could result in injury to the

community throughout project

construction, operation and

decommissioning?

Work areas will be clearly demarcated with signage and safety barriers, and access will be controlled. Only workers and project concerned members will be allowed to visit the operational sites.

Impacts to occupational health and

safety due to the excavation of rocks

during cutting trenches.

When cutting trenches and rock excavation are carried out ,PPEs will be worn and mitigations will be taken as specified in EMP.

Impacts to community health and

safety due to the transport of

construction material.

Safety measures where required shall be taken.

Occupational and Community health

and safety risk.

When considering the scope of work, magnitude of construction activities health and safety risks are not very significant. However, PPEs will be required for some workers who works cutting trenches and construction of overhead tanks etc to avoid any accidents during the work.

Impacts to community safety caused

by construction waste and disposal of

wastes from site camps.

Construction waste generated should be disposed to a site approved by PS. Garbage bins should be provided at all times and they should be collected by the PS constantly.
