"Phnom Penh is located at the intersection of four rivers arms that serve as an endless water source. But because the country had suffered from chronic civil war for decades, the water supply system became obsolete, and the supply of water did not start to improve before the 1990ies.
“In 1993, Mr. Ek Sonn Chan was appointed by the government as the General Director of the Phnom Penh Water Supply Department, and his team led officials and employees to do some basic work, like to totally repair the water supply system. He also initiated the creation of a new highly effective administrative system to issue invoices and receipts for payments. He also initiated international standard procedures to supply clean water to all residents of Phnom Penh. The Phnom Penh Water Supply Authority is successful in fighting corruption and has shown the world that the fight against corruption can be successful in a developing country through the use of simple but effective leadership, based on policies and commercial strategies that are recognized worldwide. At present, as an autonomous unit, the Phnom Penh Water Supply Authority is supplying water 24 hours a day to 90% of Phnom Penh, which has about 1.3 million citizens, and effectively controls its revenue and expenses. In the meantime, the Phnom Penh Water Supply Authority continues to further develop the clean water supply system and to strengthens the internal control of the unit.
“Since 1998, the Phnom Penh Water Supply Authority has set up a totally new supply system. The quantity of water lost as the result of broken and leaking pipes dropped from 72% in 1993 to only 6% in 2008, which is a very small quantity compared to that of other modern countries in the world. Nowadays, the collection of water bills recovers over 98% of the invoiced charges, which allows the Phnom Penh Water Supply Authority to get the necessary money back to cover its operational costs. The Phnom Penh Water Supply Authority reaches world standards due to its leading water supply system." Reported in The Mirror, Vol. 14, No. 668
