Water Main Flushing



What’s happening?

The Weymouth Water Department will be conducting our semi-annual Water Main Flushing Program beginning in South Weymouth on Monday, September 27, 2021 and continuing through to North Weymouth, finishing about Friday, November 19, 2021. The water hydrants on the main roadways will be flushed nightly between the hours of 11:00 PM and 6:00 AM. Some of the smaller residential side streets may be flushed during the daytime hours between 8:30 AM and 2:30 PM. The program will be completed in phases to minimize any potential impacts to water quality and service.  Water mains will be flushed by releasing water from selected hydrants throughout the Town.

What are the benefits of flushing water mains?

Water main flushing is an effective method of improving drinking water quality and is an integral component of a water utility's distribution system maintenance program.

Are there any short-term impacts from water main flushing?

Water main flushing can cause temporary reductions in water pressure and discolored water from increased levels of dissolved iron.  Discolored water due to increased levels of dissolved iron may not be aesthetically pleasing, but according to the Environmental Protection Agency (E. P. A.), it is not a public health threat.  The Weymouth Water Department is making every effort to minimize potential impacts from the program and will closely monitor water quality and water pressure while flushing mains.

Should Weymouth water customers take special precautions?

In general, Weymouth water customers should minimize water usage during the hours the water mains are being flushed. Any customers experiencing dirty water should run a cold water tap, closest to their water meter, for just a couple minutes to see if it clears. Some customers such as hospitals and medical facilities, and businesses that use water in their manufacturing or cleaning process, may want to more closely monitor their water quality and water pressure while the flushing program is underway. Residents should check their water before washing clothes.
