The Metropolitan Waterworks and Sewerage System (Tagalog: Pangasiwaan ng Tubig at Alkantarilya sa Kalakhang Maynila), formerly known as the National Waterworks and Sewerage System Authority (NAWASA), is the government agency that is in charge of water privatization in Metro Manila in the Philippines. It split the water concession into an east and a west concession with Manila Water being awarded one contract and Maynilad Water Services being awarded the other. The first water system in the Philippines was initiated by the Spanish Philanthropist, Francisco Carriedo y Peredo (November 7, 1690 – September 1743). Carriedo donated funds to be used in Manila; however, it was never realized until a century later, when the Spanish Franciscan friar Felix Huerta, tracked down the funds donated by Carriedo, and instigated the development of the Carriedo Water System. The construction of the water system delivered 16 million liters of water per day to 300,000 people. By 1909, the capacity of the system was increased to 92 million liters per day by the addition of pumping facilities and the construction of Wawa Dam. More information...
