Passaic Valley Water Commission will start its annual hydrant flushing on April 15, 2024

(Clifton, N.J. – April 12, 2024) – Passaic Valley Water Commission (PVWC) will begin its annual hydrant flushing throughout its service area, weather permitting, starting Monday, April 15, 2024. Flushing will take place between 8:00 am and 10:00 pm on weekdays (except holidays) and is anticipated to be completed by November. Clifton and Paterson will be flushed first and customers can stay up to date on areas being flushed by visiting

The purpose of this exercise is to ensure adequate water supply by removing accumulated sediment and maintaining the proper flow of water. During the flushing process, customers may experience temporary discoloration of their tap water and/or reduced water pressure. This discoloration is caused by sediment and minerals that have accumulated in the water mains over time. PVWC advises residents to refrain from doing laundry during the flushing period and to wait until the water runs clear before drinking or cooking with it. After flushing, customers experiencing discoloration are encouraged run their cold taps until the water is clear.

“PVWC’s mission is to safely and efficiently maintain and distribute a secure and sustainable supply of high-quality drinking water,” said Jim Mueller, Executive Director of Passaic Valley Water Commission. “Flushing is an essential part of our maintenance program, and we appreciate the cooperation and understanding of our customers during this process.”

Municipalities to be Flushed:

• Clifton

• Lodi

• West Milford (High Crest and Post Brook sections)
