Rural Piped Water Supply Project

Rural Piped Water Supply Pilot Project at a glance
This is a unique example of using surface water for a Village Piped Water Supply under Public – Private Partnership arrangement
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.
Features of the project:
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.
Raw Water Tank
Up-flow Roughing Filter (URF)
Slow Sand Filter (SSF)
Clean Water Reservoir
The processed water is to be kept in the clean water reservoir. Water delivered to the distribution network through pipeline.
