1. Background and objectives

  • Cambodia’s capital city, Phnom Penh is considered to be in need of various measures, including development of sewerage treatment facilities, because its natural purification capacity has declined significantly due to increased sewage quantity as a result of rapid urbanization and population growth in recent years, together with progress on reclamation of lakes, marshes, and wetlands.
  • Against that background, the Phnom Penh city government has developed a Master Plan on Drainage and Sewerage Improvement, and has decided to construct sewerage treatment facilities at Lake Choeung Ek, which naturally purifies the largest amount of wastewater for the city.
  • Developing this sewerage treatment facility will enable proper wastewater treatment in the applicable districts of Phnom Penh city while reducing the pollution load on the Lake Choeung Ek basin. This, in turn, will contribute for improvement of the water and hygiene environments in the relevant communities and to enhancement of the living environment of their residents.
