Water Supply

Two private companies, PALYJA and Aetra, provide piped water supply in the western and eastern half of Jakarta respectively under 25-year concession contracts signed in 1998. A public asset holding company called PAM Jaya owns the infrastructure. 80% of the water distributed in Jakarta comes through the West Tarum Canal system from Jatiluhur reservoir on the Citarum River 70 km (43 mi) southeast of the city. Water supply had been privatized by government of then President Suharto in 1998 to the French company Suez Environnement and the British company Thames Water International. Both foreign companies subsequently sold their concessions to Indonesian companies. Customer growth in the 7 first years of the concessions had been lower than before, despite substantial inflation-adjusted tariff increases during this period. In 2005 tariffs were frozen, leading the private water companies to cut down on investments.
According to PALYJA in its western half of the concession the service coverage ratio increased substantially from 34% in 1998 to 59% in 2007 and 65% in 2010.^[52] According to data by the Jakarta Water Supply Regulatory Body, access in the eastern half of the city served by PTJ increased from about 57% in 1998 to about 67% in 2004, but stagnated after that.^[53] However, other sources cite much lower access figures for piped water supply to houses, excluding access provided through public hydrants: One study estimated access as low as 25% in 2005,^[54] while another source estimates it to be as low as 18.5% in 2011.^[55] Those without access to piped water supply get water mostly from wells that are often salty and polluted with bacteria.
