World Bank Approves Financing for Wastewater System Improvement in Siem Reap City

Share to:

The World Bank has recently approved a $25.5 million credit to develop the wastewater collection network in Siem Reap City, Cambodia. The credit, with support from CDIA in terms of technical preparations, is expected to improve wastewater management in the city, resulting in better health and quality of the environment.

At present, Siem Reap’s wastewater collection network is insufficient, partially covering only 4 out of the 13 communes or 24% of the city’s surface area. While it is connected to a wastewater treatment plant, the network is not operating as designed and this has led to very low sewer connection rates.

The financial assistance from The World Bank will help the Government of Cambodia address this gap by developing and constructing secondary and tertiary sewer lines that will facilitate household connections and efficiently convey sewage to the wastewater treatment plant. It will likewise help separate the collection of wastewater from the surface run-off drainage in the city, leading to a reduction in faecal contamination in the event of flooding.

In support of this investment, CDIA is currently working with the Ministry of Public Works and Transport (MPWT) and The World Bank in the technical preparations of the project. Its assistance has anchored on upgrading the city’s existing network and sewage treatment system, strengthening its capacity to manage and operate its sanitation program, and improving the financial sustainability of the wastewater sector.

“We have taken the work from planning and feasibility, all the way through to engineering design including full tender documents for various work components,” said Neil Chadder, CDIA Program Manager. “Through this comprehensive approach, we hope to contribute in the efforts of The World Bank and the Government of Cambodia in providing the much-needed sanitation infrastructure for the residents of Siem Reap,” he added.

Key outputs of the CDIA study include the preparation of the wastewater development plan that will outline wastewater treatment plant expansion until 2030, a feasibility study report for sewerage system development, preliminary and detailed engineering designs for some infrastructure investments, and associated due diligence outputs (i.e. social, climate and environmental safeguard assessments), which were instrumental for project appraisal.

Tender or bidding documents are being finalized for sewer network construction, pumping stations rehabilitation, wastewater treatment plant improvement, and specifications for operation and maintenance, and safety equipment.

All outputs are expected to be finalized by third week of May 2019.
