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 (Package ICB 02.08; ICB 02.9 and ICB 2.11) (Rehabilitation of Distribution Networks for NRW reduction with O & M Support).

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.

Ambient Air Quality Monitoring at specific locations in 2 hours duration. The parameter is SPM, and Particulate Matter (PM₁₀, and PM_2.5), Sox, NOx and CO.

Ambient Noise Level Measurement at specific locations in day and night-time.

Drinking Quality Monitoring at specific locations. The parameters are pH, DO, Temperature, Arsenic (As), Iron (Fe) & Manganese (Mn), Chloride, Total Coliform, BOD₅ and COD.

Surface Water Quality Monitoring at specific locations: The parameters are pH, DO, Temperature, Arsenic (As), Iron (Fe) & amp; Manganese (Mn), Chloride, Total Coliform, Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).

Preparation of an Environmental Quality Test Report based on the analysis result of water pollution testing, air quality monitoring and noise level measurements.
