Large Valve Assessments – North Jersey District Water Supply Commission

The NJDWSC oversees the operation of the largest regional water supply in the state of New Jersey, including more than 95-square miles of watershed area, two major reservoirs, two river-diversion pumping stations, and a 210-million gallon/day (MGD) water filtration plant. AT peak capacity, the NJDWSC’s facilities can serve the water needs of more than three million people in Northern New Jersey. The North Jersey District Water Supply Commission was established in 1916 pursuant to N.J.S.A. 58:5-1 et seq. for the “purpose of developing municipaly water supplies” in the counties of Sussex, Warren, Hunterdon, Passaic, Morris, Monmouth, Sumerset, Bergen, Hudson, Essex, Union and Middlesex.

As its first order of business, the Commission began reviewing preliminary surveys made by Newark engineers in the late 1890’s. The Commission quickly succeeded in developing a regional consensus among municipalities and a massive 29.6-billion-gallon reservoir project was launched in 1920 with construction of a dam across the Wanaque River in upper Passaic County. The cities and towns that decided to join the Commission in building water supply projects also would be responsible for paying 100 percent of the costs. The mandate of voters had become law: No state funds would be used to build and operate the new water supplies so urgently needed by New Jersey’s expanding population and industrial growth.

During this program WWS will be looking at over 300 large valves that were installed around 1923! Our team members are conducting the field work, which includes completing repairs as needed. Almost every valve thus far has had a packing gland leak, which requires confined space entry to remove the old packing and install the new. The team continues to work through the challenges of an old system to ensure a successful outcome to this project.
