New Jersey American Water, which serves 2.9 million customers in the state including Somerville, will be performing its annual flushing of the water distribution system starting next week and continuing into the fall. The flushing process involves opening fire hydrants to clear out sediment and ensure proper pressure and flow, which may result in temporary low water pressure or discoloration for customers.

Why it matters

This routine maintenance is required to meet water quality standards and keep the system functioning properly. While inconvenient for customers in the short term, the flushing helps prevent larger issues down the line and ensures reliable water service.

The details

The flushing process involves simultaneously opening fire hydrants in specific areas to create increased water flows. This also includes flushing blowoff valves on dead-end water mains. Customers may experience low water pressure or discolored water during the flushing, and are advised to run cold water until it clears and avoid using washing machines or dishwashers until the flushing is complete.

• The flushing will begin next week and continue into the fall months of 2026.
• New Jersey American Water will notify customers when flushing is taking place in their area.
