INTRODUCTION 1. The Urban Water Supply Project (UWSP) – Cambodia is an ongoing undertaking funded through loan by the Asian Development Bank (ADB) which aims to improve water supply infrastructure and services in selected provincial Water Works. The project consists of four main outputs, namely: • Output 1: Improvement of water supply systems in seven towns; • Output 2: New water supply system for Stung Treng; • Output 3: Expansion of water supply coverage in Siemreap; and • Output 4: Project implementation support. 2. One intake pump with a capacity of 55kW and an additional pipe laying in some parts of Pursat Municipality and Kandieng District of Pursat province were completed in 2019. On the pipe laying works, Pursat Provincial Water Works (PWW) is currently proposing to expand the distribution network for another 15,500m to supply 602 households living in Pursat Municipality, Dandieng District and Bakan District by 2023. 3. The Project is classified as a Category C Project according to the ADB Safeguard Policy Statement (SPS) (2009). Environmental impacts are generally minor for the Pursat sub-project. Additional pipe laying works will be undertaken within the right of ways (ROWs). A due diligence review has been prepared for the subproject. II. SUBPROJECT DESCRIPTION 4. Pursat is located in western part of the country along National Road (NR) No. 5, about 174km north west of Phnom Penh. Water source of Pursat water supply system is Pursat stream bisects the province, running from the Cardamoms in the west to the Tonle Sap in the east. Water level in the stream is about 5-8m in depth during rainy season and is about 1-2m in depth during dry season. It is important to note that there is no record of water shortage in both seasons in the stream. At intake point of the supply system, there are two water intake heads – low and medium levels – to adjust to the level of water in both seasons. The raw water will be pumped by two vertical pumps (55kW each and the remaining one is on standby) and treated in a conventional water treatment plant before it is distributed to final consumers. 5. After completion of installation of items requested in previous proposal including: one intake pump and pipe laying works in some parts of Pursat Municipality and Kandieng District in 2019, Pursat Provincial Water Works would like to propose some additional expansion works since the recently completed works have not met people demand as well as the goal of the Ministry of Industry and Handicraft (MIH) and the Royal Government of Cambodia (RGC) as whole that aim to supply clean water to people up to 90% in 2023 and 100% in 2025. In addition, most of urban areas have already been equipped with DBST roads, except water supply that has not reached people living in those areas yet. 1 6. The proposed extension lines cover 10 villages in 6 communes/ Sangkat of 3 districts/ Municipalities of Pursat province with a total length of 15,500m (Table 1 and Figure 1). Pursat Provincial Water Works also requests for 602 water meters. With this proposed expansion line, it is expected that 602 households will be benefited from this expansion, all of which are badly in need of clean water. The proposed expansion lines are within Pursat Provincial Water Works service coverage areas and have enough water pressure at the end of existing secondary pipelines to further distribute to final consumers through tertiary pipeline. 2 Table 1: Name of Villages and Proposed Lengths of Secondary and Tertiary Pipelines No.
