    Rural Piped Water Supply Pilot Project at a glance

    • A Brotee – SDF* public private partnership arrangement
    • Project area: Three villages in Chapai Nawabgonj district (Chamagram – Laharpur - Laxmipur)
    • Production capacity of water treatment plant: 3,00,000 liters of safe drinking water per day 
    • Average daily demand: 135,000 liters
    • Source of raw water: Mohanonda River
    • Treatment method: Ecological surface water treatment by Slow Sand Filter (SSF) after sedimentation and filtration in Up-flow Roughing Filter (URF) chambers
    • Distribution system: 6.6 Kilometers pipeline network
    • Beneficiaries: Approximately 6000 people (1137 households including 40 ultra poor families)

    This is a unique example of using surface water for a Village Piped Water Supply under Public – Private Partnership arrangement

    Project Summary:

    The purpose of the project is to provide safe drinking water to the first identified arsenic affected people of Bangladesh. Since identification of the population of Chamagram, Laxmipur and Laharpur as arsenic affected, no intervention has been initiated there. Several attempts have failed to extract arsenic free water from either shallow or deep aquifer. Again deeper exploration is not possible due to natural hard rock formation. Brotee proposed to extract surface water through a Surface Water Infiltration System (SWIS) from the perennial river Mohanonda flowing by the villages. Chemical contamination of river water is low and well within acceptable level. 

    Receiving clean water by households

    The project is serving a part of the whole community of 4,484 persons which will grow to approximately 5,860 within the project period of 15 years. Major activities of the project include the production of well, semi-ground reservoir, elevated reservoir, pump house, distribution network and house connection with stand post.


    Baroghoria is the area where arsenic in ground water was first identified in 1993. Baroghoria still does not have any sustained safe drinking water source for its community. The people have waited for a long time for such a scheme that can ensure them a regular supply of safe water particularly for drinking

    Receiving clean water by households

    There are about 17658 families living in these villages. There is acute scarcity of drinking water, particularly in the dry season when ground water table goes down due to higher abstraction. Ponds become dry as the mentioned locations are in the low water table aquifer belt. Ground water in shallow depth is found to be arsenic contaminated rendering it unfit for safe drinking. Therefore, a piped water supply pilot scheme based on surface water source was the choice for Brotee and for the rural population of these villages.

    Specific Objectives:

    1. To facilitate alternative surface water option for rural water supply in arsenic prone villages
    2. To improve access to safe water supply in the villages
    3. To encourage public private partnership in rural water supply delivery
    4. To sustain the scheme by maintaining water quality protocol up to 15 years
    5. Full cost recovery of operational and a part of the capital cost of the scheme over the project period

    Features of the project:

    1. Particularly this Ecological Surface Water Treatment System will demonstrate the possibilities to use surface water as source for the rural piped water supply 
    2. Development of Ecological Surface Water Treatment System for piped water supply will provide increased access of safe water supply to the household which will contribute towards improvement of public health, mitigation of arsenic problem
    3. Improvement of personal hygiene practice due to availability of running water for domestic purpose
    4. Demonstration of participatory management and cost recovery initiative by improved service for replication
    5. Rural employment will increase and poverty reduction for increased economic activities

    Location & beneficiaries of the project:

    Three villages of Chamagram, Laxmipur and Laharpur at Baroghoria Union of Sadar Thana, Chapai Nawabgonj are located at a distance of about four kilometers from Chapai Nawabganj town. In the North lie Naya Lahaganga and Moharajpur Unions. Baliadanga Union is in the East and Ujirpur Union in the West of location, while the Mahanonda River lies in the South, across which is the town of Chapai Nawabganj


    The project is expected to serve 1137 households including about 40 vulnerable households. The average family seize is 5. About 40 vulnerable families identified in the community will also be connected with the piped water system.


    Components of the project:

    Based on the findings of feasibility study, Brotee created this ecological treatment technology by setting up (1) an Intake Well, (2) a high-rise Raw Water Tank, (3) Sedimentation Tanks, (4) Up-flow Roughing Filter (URF) chambers, and (5) Slow Sand Filter (SSF) chambers. The filtered water is to be kept underground Supply Tank and distributed to pipelines by a pump. The combination of URF and SSF with continuous flow of water ensures growth of algae and microorganisms which “eat up” harmful pathogenic bacteria and viruses.

    Intake Well
    A dug well installed with RCC rings with sealed bottom on the bank of the Mohanonda River to deliver the water to the treatment plant.

    Treatment Plant

    Raw Water Tank
    The water delivered from the Intake Well is to flow down through a pipe into the Raw Water Tank (RWT) which is installed above the Supply Tank and pump station at the treatment plant site.

    Sedimentation Tank
    The main role of the sedimentation tank is to reduce turbidity and dissolved substances of raw water.

    Up-flow Roughing Filter (URF)
    The role of roughing filter is to decrease the turbidity of raw water as pretreatment to reduce the burden of a sand filter.

    Slow Sand Filter (SSF)
    The role of SSF is to remove harmful pathogenic bacteria and viruses.

    Clean Water Reservoir

    The processed water is to be kept in the clean water reservoir. Water delivered to the distribution network through pipeline.
