Potable water supply in the province reaches the populace through three levels namely: Level I (point source system), Level II (communal faucet system), and Level III (individual connections). A well or spring is the pinpointed water source in areas where houses are few as the system is only designed to serve 15 to 25 households. As of 1997, there were 128,571 Level I water system users in the province. The communal faucet system (Level II) serves the rural areas while the Level III system is managed by the Local Water Utilities Administration (LWUA). The system provides individual house connections to all second and first class private subdivisions.
