The proposed West Bengal Drinking Water Improvement Project (WBDWIP) aims to provide safe, reliable and continuous drinking water as per Government of India’s (GOI) standard to about 2.6 million people in the arsenic, fluoride, and salinity affected selected areas of North 24 Parganas, South 24 Parganas, East Medinipur and Bankura districts of West Bengal. 2. The project will adopt a sector approach, and subprojects will be selected and proposed for funding adhering to the agreed Subproject Selection Criteria (SSC). Project districts are North 24 Parganas (with two blocks of South 24 Parganas included for distribution network), Bankura and East Medinipur, and subprojects to be covered under the Project will be within these districts only unless otherwise agreed with ADB. Subprojects proposed under the Project stem from a district-wide comprehensive water quality and sustainability planning and completion of the Drinking Water Quality Action Plan (DWQAP) for the concerned district. 3. WBDWSIP will be implemented over period of 3 years after award of contract and operate and maintenance period is of 2 years. 4. The Subproject. The district of Bankura has high concentration of fluoride and iron in groundwater, including the blocks of Majia and Gangajalghati. The blocks reported to have recurrence of fluoride contamination in groundwater. Provision of water supply distribution system has been taken up in this subproject under the WBDWSIP for the affected blocks of Mejia and Gangajalghati. A parallel subproject, implemented under WBDWSIP, will provide bulk water supply (treated water) to this subproject for further distribution to the households in the project area.The subproject includes the following civil works components: (i) construction of 30 overhead reservoirs (OHRs) in Mejia and Gangajaghati Blocks; (ii) laying of 1460 km distribution network and (iii) provision of domestic water meters for household water connections with water meters. 5. Project Implementation Arrangements. Public Health Engineering Department (PHED) of Government of West Bengal is the executing and implementing agencyfor the WBDWSIP. Project Management Unit (PMU) exclusively established in PHED for the WBDWSIP will implement the project. PMU is assisted by district level Project Implementation Units. Safeguard and Gender Cell (SGC) in the PMU is responsible for safeguards compliance. Project Management Consultant and PIU-wise Design, Supervision and Institutional Support Consultant (DSISC) will assist PMU and PIUs in implementation and management of the project. 6. Screening and Assessment of Potential Impacts. ADB requires the consideration of environmental issues in all aspects of the Bank’s operations, and the requirements for environmental assessment are described in ADB’s Safeguard Policy Statement (SPS), 2009. As per the GOI EIA Notification, 2006, this subproject does not require EIA study or environmental clearance. The potential environmental impacts of the subproject have been assessed using ADB’s Rapid Environmental Assessment Checklist for Water Supply. The potential negative impacts were identified in relation to pre-construction, construction and operational period. It should be noted that, this IEE document has been updated for the zones, where construction has commenced by 29th February 2020 in Mejia and Gangalghati block of Bankura district. The detail of the zones are given in Section II of this report. 7. Categorization. Based on results of the assessment and ADB’s SPS, the subproject is classified as environmental Category B, i.e., the subproject is judged to be unlikely to have any significant adverse environmental impacts. However, an initial environmental examination is required/advisable. 8. Description of the Environment. The subproject components are located in Mejia and Gangajalghati block of Bankura District which is situated on the westernpart of the State of ii West Bengal. The total area of the district is 6882 square kilometers (km2). It extends from 23038’ north Latitude and between 86036’
