Dhaka Water Supply Network Improvement Project (DWSNIP): Consultancy Services for Environmental Quality Testing and Assessment (Air, Noise and Water Quality) for Construction of water supply line at Dhaka City (ICB 02.08)

Dhaka Water Supply Network Improvement Project (DWSNIP) aims to improve provision of sustainable, reliable, and climate-resilient water supply in Dhaka city. It will enhance the distribution network efficiency gains achieved under two previous Asian Development Bank (ADB) financed projects to Dhaka Water Supply and Sewerage Authority (DWASA) for improving service delivery and capacity building. The estimated cost of the Project is US$ 408 million. DWSNIP impact will be safe drinking water made available for all urban population, which is aligned with the Seventh Five- Year Plan, 2016-2020. The outcome will be sustainable provision of more reliable, improved, and climate-resilient water supply in Dhaka city ensured.
