Phnom Penh Water Supply Authority (PPWSA) has selected Singapore-based company Moya Dayen to construct the first of two water-pumping stations at Niroth Water Supply Station on the Mekong River, a PPWSA official said Tuesday. Ek Sonn Chan, PPWSA director general, said the US$13.4 million project is scheduled to start next month and will take approximately two and a half years to complete. Ek Sonn Chan said the station will be able to produce about 130,000 cubic metres per day. A tender for the second water treatment project is also almost complete, he added.
