 Despite a number of policy papers that were mainly focused on water supply and despite various projects funded by external donors, increases in access have remained limited (1% for water and 5% for sanitation between 1990 and 2004).The responsibility for water and sanitation policies within the government rests with the Ministry of Water and Housing, and the main service provider is the National Water Commission.An autonomous regulatory agency, the Office of Utilities Regulation, approves tariffs and establishes targets for efficiency increases.
