The proposed West Bengal Drinking Water Sector Improvement Project (WBDWSIP) aims to provide safe, reliable and continuous drinking water in accordance with guidelines of Ministry of Drinking Water and Sanitation, Government of India and with the Vision 2020 of GoWB to about 6 million people in selected Arsenic, Fluoride, and Salinity affected areas of North 24 Parganas, South 24 Parganas, Bankura and East Medinipur districts. The Project will ensure drinking water security through 24/7 piped water supply schemes in the areas covered, strengthen the institutional structures and build the capacities of stakeholders at all levels of service delivery for sustainable operation and maintenance and sustained public health improvement. 2. WBDWSIP will be implemented over a 6-year period beginning in 2019, and will be funded by ADB via a sector loan modality. 3. The Subproject. Creation of surface water based bulk water supply system to meet the water demand for the blocks of Nandakumar, Chandipur ,Nandigram I and Nandigram II blocks in Purba Medinipur district under the WBDWSIP. The sub-project will also help in reducing the incidence of ground water depletion and intrusion of salinity in ground water. The selected blocks are located in the western bank of the River Rupnarayan. spreading over 39 Gram Panchayats and covering 345 villages and 745 habitations (as per Census 2011).The subproject includes the following work components: (i) Raw water intake (fixed jetty type) and pumphouse –substation,(ii) 112 MLD capacity water treatment plant with all appurtenances, civil & electro-mechanical works, including Chlorination sludge lagoons, (iii) 18 km long raw water pumping mains, (vi) 32km long DI K9 clear water transmission mains of assorted diameter 600 mm – 1100 mm to carry treated water from WTP to proposed GLSRs of Nandigram I & II , Nandakumar and Chandipur blocks, and and MS transmission main of 2 km of assorted diameter 700 mm – 1100 mm, (vii) Construction of RCC Bridge of width 5.0 m over Haldi River having length 600 m approx. for carrying 1000 mm dia (K9 grade) and other utility, (viii) Operation and maintenance of the Plant for a period of two years after commissioning and takeover. 4. Project implementation arrangements. Public Health Engineering Department (PHED) of Government of West Bengal is the executing and implementing agency for the WBDWSIP. Project Management Unit (PMU) exclusively established in PHED
