Phnom Penh Water Supply Expands to 1.7 million Residents
–Inauguration Ceremony of Niroth Water Supply Facilities on June 4th, 2013–


The inauguration ceremony of Niroth Water Production Facilities takes place at 7:30am on 4th June 2013 at Niroth Water Treatment Plant, presided over by Samdech Akka Moha Sena Padei Techo Hun Sen, Prime Minister of the Kingdom of Cambodia, Japanese Ambassador H.E. Yuji KUMAMARU, and French Ambassador H.E. Serge MOSTURA.

At present, a total of three existing water plants in Phnom Penh (Chroy Changwar WTP, Phum Prek WTP, and Chamcar Morn WTP) are running over capacity to meet the demands of approximately 1.23 million residents. With Niroth Water Production Facilities come into play with full capacity, the production capacity of Phnom Penh Water Supply will increase from 336,000 m3/day to 466,000 m3/day, which enables Phnom Penh Water Supply Authority (PPWSA) to supply safe and clean water to a total of approximately 1.7 million of the urban dwellers by the end of 2013.

Niroth Water Supply Project is the second expansion of water production project following Chrouy Changwar Stage 2 and implemented under the co-financing of Phnom Penh Water Supply Authority (PPWSA), Japan International Cooperation Agency (JICA) and Agence Française de Développement (AFD). This will allow PPWSA to install tens of thousands of new water connections each year to supply safe and clean water to one of the poorest population of the city. The main beneficiary of this project includes the residents in the West Phnom Penh area, one of the hot spots for dynamic urbanization and industrialization, as well as to the new urban dwellers in 26 communes - including Takhmao City - which are recently annexed to Phnom Penh capital city.

The construction of the Niroth Water Production Facilities started in August 2010 and completed in June 2013. The total amount of project is 90.4 million USD, of which Japan's ODA Loan covered approximately 40.6 million USD for the construction of Water Treatment Plant, Treated Water Reservoir, Treated Water Pumping Station, Treated Water Transmission Mains, and Secondary Distribution Main. AFD funded a total of € 16 million (or 20 million USD) to cover the costs of the construction of Intake, Raw Water Transmission Mains, Primary and Secondary Distribution Mains and construction supervision consultant, and PPWSA covered the total amount of 29.8 million USD to cover the cost of land acquisition, power supply facilities, civil works, taxes and duty for the project.

PPWSA has just signed a new € 30 million (Approx. 39 million USD) loan with AFD to double the water production capacity at Niroth facility that will enable PPWSA to meet drinking water demand in Phnom Penh and its urban area by 2020. In addition, JICA's grant project to introduce Photovoltaic (Solar) Power Generation System (Approx. 7.2 million USD) is expected to be completed by June, 2013. Electronic power generated from this new solar system will supplement an overall operational electronic power required at the Niroth facilities.

In 1993, only 20% of the residents in Phnom Penh enjoyed the water supply system; however over the last two decades, the water coverage of the city grew to 85% in 2012, according to PPWSA data.

The project is in line with Royal Government of Cambodia's effort to rehabilitate and construct key physical infrastructures for water supply and sanitation and expected to act as a momentum in advancing the Cambodian Millennium Development Goals to improve access to safe drinking water to 80% of urban population by 2015.

Thanks to the quality of its network, the technical and financial support from funding agencies and to its exemplary management, the PPWSA is achieving outstanding levels of technical and financial performance. It has become a real success story in Cambodia and elsewhere in the world.
