Where the water comes from
Ridgewood Water's main water source is purchased surface water. It buys treated water from Hawthorne Water Department, Veolia Water New Jersey Franklin Lakes, Veolia Water New Jersey Hackensack, Passaic Valley Water Commission. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while Ridgewood Water is responsible for its own service line inventory and replacement program.
