REcd. 21.1.21 SFG Log: 4481 Updated Initial Environmental Examination January, 2021 Loan 2806 IND: Assam Urban Infrastructure Investment Program - Guwahati Water Supply Subproject – “Construction of Water Storage Reservoir and water Transmission pipelines and Allied works at Guwahati” Prepared by Guwahati Development Department & Urban Development Department, Government of Assam for the Asian Development Bank Preface During June 2011 ADB TA team finalized draft Initial Environmental Examination (IEE) Report for Guwahati water supply project covering water intake, water treatment plant, water reservoir, water transmission and distribution for Tranche 1 loan processing. That Report already disclosed. Later it was decided to consider Intake, water treatment plant, raw water transmission and distribution under Tranche 2 funding and at the same time few locations of water storage reservoirs changed and accordingly route for transmission main also changed. The IEE report was updated in April 2015 due to change in scope. This is Further Updated Initial Environmental Examination Report for Tranche 1 Water supply sub project for Guwahati covering only Construction of three numbers Water Storage Reservoir and water Transmission pipelines including new scope “Inter-linkage of water supply pipeline from the main outlet of Ramsahill Reservoir to Gopalnagar Transmission Main Line near Sunchali Beel Par” and Allied works at Guwahati.

Asian Development Bank (ADB) has approved the Assam Urban Infrastructure Investment Program (AUIIP), a $200 million Multi-Tranche Financing Facility (MFF) on 20th September 2011, to improve water supply of South Guwahati East Zone1 as well as drainage and solid waste management (SWM) of Dibrugarh 2 . AUIIP will also provide support for ongoing urban reforms and associated capacity development for improved service delivery, urban governance and financial management in Guwahati and Dibrugarh. Loan 2806-IND: AUIIP-Tranche 1 for $81 million was approved on 18 November 2011, signed on 9 March 2012 and declared effective on 25 April 2012. On March 2014, $20 million and in September 2016, $10 million of Tranche 1 was cancelled and reallocated to the MFF pool. After that Tranche 1 (Project 1) stands at $51 million. The original loan closing date was 30 June 2018. The loan closing date has been extended till 29 June 2021. 2. Project 1 contains various sub-projects which are (i) 2 sub projects on Water Supply System in South East Guwahati (ii) 1 sub project on Storm Water drainage in Dibrugarh and (iii) 4 sub projects on Solid Waste Management in Dibrugarh. 3. The Government of Assam’s Guwahati Development Department (GDD) is the executing agency. A state-level PMU, headed by a Project Director (PD), established as the Implementing Agency which is in-charge of overall execution and technical supervision, monitoring, and financial control of all activities under the project. Project Implementation Units (PIUs) dedicated exclusively to the project set up in Guwahati and Dibrugarh. The PIUs headed by a senior technical officer and assisted by qualified and experienced officers seconded from ULBs, finance and other line departments. The PIUs responsible for the day-to-day activities of project implementation in the field and under the direct administrative control of the PMU. 4. The Safeguards implementation Arrangement of AUIIP includes full time Environmental Specialist and Resettlement Specialist in PMU Guwahati and PIU Dibrugarh to monitor the projects in both the cities. The PMU assisted by the Design Management Supervision Consultant (DMSC).An Environment Specialist as part of the DMSC team is to assist the PMU in updating the IEE during detailed design stage, implementation (as per requirement) and monitoring of the subproject’s EMP during the construction stage. ADB will review and approve all final IEEs prior to contract award. 5. ADB requires the consideration of environmental issues in all aspects of its operations, and the requirements for environmental assessment are described in ADB’s Safeguard Policy Statement (SPS), 2009 and Public Communication Policy 2011. According to the SPS, environmental assessment is required for all subprojects under a MFF modality. 6. The overall investments under AUIIP in Guwahati is aimed at providing improved quality and regular 24 hours a day water supply to about 5,10,000 residents in the south- eastern zone of Guwahati by 20303.This will involve 1) Expanding water production capacity through water intake works, 98million liters per day (MLD) water treatment plant (expected to 1 Guwahati has been divided into four water supply zones; one north of the Brahmaputra river and three to the south. In south Guwahati, the west zone is being financed under Jawaharlal Nehru National Renewal Mission (JNNURM), the central zone by Japan International Cooperation Agency (JICA), and the east zone has been identified for ADB assistance. 2 Dibrugarh suffers from prolonged local flooding during the annual monsoon. Because of the lack of sewerage and inadequate solid waste management much of the areas in the city’s drainage system becomes choked and severely polluted with un- treated wastewater. 3The Guwahati water supply sub project ensures piped water supply 24 hours a day for nearly 5,10,000 people (by 2030) who presently depend on bore wells and water tankers which would adversely impact the ground water table in the long run and cause negative impacts on the micro-climate of the city. The assured piped water supply to individual houses when the project is completed will reduce wastage of water and transportation of water by tankers and indirectly help climate change in a positive way. 1 be considered under proposed AUIIP II4), clear water pumping and primary transmission mains, new distribution systems (expected to be considered under proposed AUIIP II), six water storage reservoirs (3 of them are expected to be considered under proposed AUIIP II) and machinery; and installing bulk and consumer meters. 5 Installation of 100% new distribution pipes; limiting NRW to 15% as per the Ministry of Urban Development’s (MOUD’s) benchmark of 15% and the move from flat to volumetric rate tariffs will result in effective demand management and water conservation.
