ADB to support water supply and sanitation project in Cambodia


The Asian Development Bank (ADB), an international development finance institution, has approved a $50m loan to aid Provincial Water Supply and Sanitation Project in four cities of Cambodia.

ADB will administer a $10m grant by the Government of Japan for the Joint Crediting Mechanism and a €40m ($43.54m) loan from Agence Française de Développement (AFD), a public financial institution. 

It will also administer a €4.67m ($5.09m) grant from European Union’s Asia Investment Facility to support energy efficiency measures, free household sewer connections, and capacity development.

ADB Southeast Asia Department urban development specialist Michael White said: “As urbanisation in Cambodia continues at a rapid pace, there is a need to ensure that people have access to safe and reliable water supply and sanitation services to support their productivity and daily lives, and improve their urban environment.

“ADB will work closely with the Government of Cambodia to ensure that people, particularly in the rapidly growing urban centres in the country, have access to these basic urban services.”

The increase in Cambodia’s population has increased the need for basic urban services such as water supply and sanitation in secondary cities like Battambang, Kampong Cham, Siem Reap and Sihanoukville.

Currently, only 42.2% of the urban population except Phnom Penh have access to piped water supply, 80.2% have access to improved sanitation and only 10.7% have access to sewerage and wastewater treatment.

Expected to be completed by the end of 2022, the project aims for an improved water supply in Battambang and Kampong Cham for an additional 209,000 people or about 40,000 connections.

Two water treatment plants with a combined capacity of 61,600 cubic meters per day and new distribution networks with a combined length of 161km will be set up in Battambang and Kampong Cham.

The project also includes a new wastewater treatment plant in Battambang, expansion of the wastewater treatment plant at Sihanoukville, with a combined capacity of more than 31,000 cubic meters per day, and an additional 37km new sewer pipeline.

A new septage management system will be built in Kampong Cham and a new 3.7km trunk sewer in Siem Reap to reduce pollution and improve the urban environment.
