The Government of Cambodia has inaugurated the USD23 million Takhmao Water Treatment Plant and the USD28 million Koh Norea Replacement Intake Station to improve clean water supply in southern Phnom Penh and Takhmao city. The treatment plant can produce 30,000 cubic meters of clean water daily, while the intake station has a capacity of 460,000 cubic meters per day, raising Phnom Penh Water Supply Authority’s (PPWSA) total capacity to over 1 million cubic meters per day.
Developed under PPWSA supervision and built by Japan’s KKKCT Consortium between March 2022 and July 2025, the projects were funded through Japanese grant aid via the Japan International Cooperation Agency (JICA). The facilities are expected to provide around 23,000 new household, business, and industrial connections. Officials highlighted the projects’ role in supporting Cambodia’s Clean Water for All initiative and Sustainable Development Goals 2030.
The new intake station will also support future expansion of the Niroth Water Treatment Plant and serve key development areas, including the Techo International Airport zone.
