Khulna Water Supply Expansion Project Preparation Study Reaches Final Stage

Share to:

In a significant stride to address the water challenges in Khulna, Bangladesh, the ADB-CDIA-supported project preparation study (PPS) for Phase Two of the Khulna Water Supply Project (KWSP-2) is nearing completion. 

Undertaken by a multidisciplinary team of international and local experts, the PPS encompasses a comprehensive water supply investment program to safeguard the water needs of Khulna City’s current and future populations. 

Khulna, a key city in Bangladesh, has grappled with water supply challenges due to increasing dry-season salinity and population growth. In response, the Khulna Water Supply and Sewerage Authority (KWASA) collaborated with ADB-CDIA to conduct a PPS for the anticipated ADB loan for KWSP-2. The PPS was aimed at developing an investment program; enhancing KWASA’s capacity; assimilating lessons from other initiatives; and evaluating the city’s institutional, financial, and governance aspects to ensure a sustainable water supply.  

Over the past 10 months, CDIA’s team of consultants conducted surveys, assessments, and stakeholder consultations to delve deeper into the city’s water supply situation, looking at various aspects such as water consumption, water resources and infrastructure, use of groundwater, and impacts of climate change, among others.  

They then proposed investments to meet the immediate (2035) and ultimate (2050) water requirements of Khulna, with three alternative investments assessed comprehensively, while considering a salinity management perspective. They likewise proposed solutions for water transmission main, managed aquifer recharge utilizing natural ponds, solar-powered pumps, robust and functioning DMA and SCADA systems, smart metering systems toward non-revenue water management, as well as consideration for treatment by desalination techniques in the future.  

The PPS has determined the necessity of conducting a more detailed scientific hydrological study to provide the basis for prioritizing salinity mitigation measures that will safeguard Khulna’s freshwater resources. Undertaken by the Urban Resilience Trust Fund of ADB, the supplementary scientific study will cover surface water resources, groundwater hydrology, land use and land cover, water demands from stakeholders, and private tubewell characterization. Findings from this study will be integrated into the final PPS report. 

“As the city prepares to embark on the next phase of project development, we hope that the findings and lessons from our PPS will guide KWASA toward a future where clean and reliable water is available to all every day and in every season,” said Brian Capati, CDIA’s Urban Development Specialist in charge of the KWSP-2 PPS.
