|Description||The proposed project aims to improve the water supply system in the country's capital, Dhaka, by making it more reliable, sustainable, and climate-resilient. It will consolidate and enhance the gains made in the efficiency of the water distribution network achieved under two ongoing Asian Development Bank (ADB) projects, and improve the service delivery and the capacity of the Dhaka Water Supply and Sewerage Authority (DWASA).|
|Project Rationale and Linkage to Country/Regional Strategy||
Enhancing efficiency gains. The development of urban infrastructure has not kept pace with rapid urbanization in Bangladesh. Providing sufficient drinking water to meet growing demand in Dhaka has been particularly challenging due to the city's average annual population growth rate of 3.6% since 2005, which has far exceeded the 1.1% national average. The two ongoing ADB projects have improved the distribution networks in 7 of the DWASAs 10 zones by establishing district metered areas (DMAs) and working to reduce the ratio of nonrevenue water in the system in each DMA. Unlike before, the piped water supply in the DMAs commissioned so far is now available 24 hours a day. Physical water losses from these systems have been cut from 40% to less than 15%. Good quality potable water from system taps is now assured. The projects have also added 9,500 water connections.
However, DWASA still has challenges. It needs to expand efficiency gains throughout its service area. It must reduce overall physical losses and the estimated 26% overall nonrevenue water ratio in its system operations.
Increasing climate change resilience. Climate change is likely to exacerbate the threats to Dhaka's already vulnerable water security. The decline in water availability due to altered precipitation patterns and increased evapotranspiration caused by higher temperatures, and the rising incidence of water pollution from flooding are major climate risks. The use of the DMA-based approach reduces the city's vulnerability to water shortages by making more water available through efficient water management systems. DWASA also needs to adapt to future climate change effects by enhancing its institutional abilities in the sustainable operation and maintenance (O&M) of DMA systems. In addition, it must be able to monitor water quality to detect and mitigate water pollution and salinization. A public program to make the public aware of the need to conserve water will be necessary to prepare the city to withstand adverse climate events. Improving access to piped water in LICs will increase the resilience of the poor in the face of climate change and the risk of natural disasters.
Sustainable management of district metered areas. Managing DMAs professionally and sustaining the newly achieved low levels of nonrevenue water ratios are both critical to keeping DWASAs operations sustainable. DWASAs capacity to carry out O&M in the DMAs must be improved, since a growing number of DMAs will be commissioned and handed over by contractors to DWASA operational staff under the ongoing projects. DWASA needs to institutionalize the DMA-based approach by updating operating procedures, training and orienting operations staff in DMA management, and developing a comprehensive DMA management plan. The project will help DWASA make the necessary institutional transformation into a highly efficient and financially sound water utility.
|Impact||(i) safe drinking water made available for all urban populations (Seventh Five-Year Plan, 2016 -2020); and (ii) adaptive capacity of water sector enhanced for reducing climate change vulnerability (National Strategy for Water Supply and Sanitation).|
|Description of Outcome||Sustainable provision of a more reliable, improved, and climate-resilient supply of water ensured in Dhaka City|
|Progress Toward Outcome||Works towards provision of a more reliable, improved, and climate-resilient water supply in Dhaka City are ongoing under five major civil works contracts. On completion of these works, uninterrupted, 24-hour supply of piped water will be delivered residents of the project area, water supply pressure of at least 1 bar (10 meters) at consumer end will be achieved, nonrevenue water will be reduced to below 10%, and 98% of water quality test results within DWASA distribution systems will meet country standards.|
|Description of Project Outputs||
Distribution network strengthened.
Sustainable managerial capacity of DMA enhanced.
Capacity for quality service delivery enhanced.
|Status of Implementation Progress (Outputs, Activities, and Issues)||Strengthening of the distribution network in new district metering areas (DMAs) covered by the project is ongoing. About 414 kilometers (km) of water distribution network has been rehabilitated, and 24,400 household and community connections have been partially rehabilitated, including 10,500 household with replacement of meters. The remaining works of the earlier Dhaka Water Supply Sector Development Program have been successfully completed. The implementation of sustainable nonrevenue water reduction plan (SNRWRP) is ongoing and will be implemented towards the end of the project period. Till date, a total of 159 DWASA staff are trained (30 staff on DMA management, 19 staff on hydraulic network modeling, 95 staff on water quality monitoring, and 15 staff on GIS) besides 25 staff on gender mainstreaming. The upgradation and implementation of SOP is ongoing and will be implemented towards the end of the project period. The implementation of SCADA system in all DMAs is being bid out and AMR meters are to be implemented in three model DMAs. Activities for enhancing DWASA's capacity for quality service delivery is yet to be undertaken. These would include (i) upgrading and implementing the five-year corporate business plan; (ii) implementing awareness campaign program in seven zones; (iii) organizing and implementing 35 CBOs in low income communities (LICs); (iv) upgrading and implementing the water quality monitoring system; (v) training 50 DWASA staff for operationalizing laboratory equipment; (vi) implementing gender action plan; and (vii) preparing bidding documents for two projects.|
