Where the water comes from
Montclair Water Bureau's main water source is purchased surface water. It buys treated water from Passaic Valley Water Commission, N.J.D.W.S.C. - Wanaque North. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while Montclair Water Bureau is responsible for its own service line inventory and replacement program. It sells water to 4 other water systems: Cedar Grove Water Dept, Glen Ridge Water Dept, NJ American Water - Short Hills, NJ American Water - Little Falls.
