Parsippany's Water May Be Discolored, Slow, Here's Why

PARSIPPANY, NJ — Parsippany residents may notice overnight water changes as the township Water Department begins its annual Hydrant Inspection & Flushing Program.

The work is scheduled to take place during the overnight hours, starting this past Monday and concluding each day at 6 a.m. According to the township, the program is expected to continue through May 22, 2026.

The township said the annual program is part of routine water system maintenance. According to the notice, the work involves systematically opening fire hydrants to increase water flows and flush minerals and deposits from water mains. The township described the program as essential to maintaining the water system.

The township said flushing the system will not interrupt water service. Still, residents in areas where crews are working may notice a temporary drop in water pressure or discolored water. According to the notice, that is normal and is not a health hazard.

If discolored water appears, the township advises residents to let the cold water tap run until the water is clear. Residents are also advised to check for discolored water before using a washing machine or dishwasher. If water pressure or water volume remains low after flushing has been completed, the township said to check faucet screens for trapped particles.

The Water Department can be reached at 973-263-7099, Monday through Friday from 7 a.m. to 4 p.m. The township asked for residents' cooperation as the spring maintenance program gets underway and continues through late May.
