Greater Houston gets most drinking water from surface reservoirs — notably Lake Houston, Lake Conroe and Lake Livingston — treated at regional water plants with coagulation, filtration and disinfection (chlorination). Several suburban systems also use groundwater wells and local treatment before distribution.
