Where the water comes from
Southern Madison Water District's main water source is purchased surface water. It buys treated water from Berea Municipal Utilities. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while Southern Madison Water District is responsible for its own service line inventory and replacement program. It sells water to 1 other water system: Western Rockcastle Water Assoc.
