Water Main Flushing Program

Needham's water distribution system has been in operation for a very long time. The system we use today opened in 1887, making some of the Town's water mains more than a century old. To address the aging infrastructure, the Needham Water, Sewer and Drains Division has an aggressive capital improvement program that includes replacing old water mains. By doing so, it reduces the frequency of water main breaks throughout the town.

Water that flows through newly relined or replaced mains is cleaner. As an additional measure, the Needham Water, Sewer and Drains Division regularly flushes parts of its system where standing water might have acquired impurities from sitting too long in the pipes.

When Flushing Occurs

Flushing is performed during the spring and is achieved by closing gate valves in the water mains in the street to isolate the water, which is then directed through the hydrant. The water creates a scouring velocity that will remove any material that has settled within the pipes. This flushing continues until the water is clear. The flushed water from the hydrant is directed into the gutters and then into the storm drain.

Program's Purpose

The purpose of the Water Main Flushing Program is to improve drinking water quality throughout Needham. The flushing process may cause discolored water and a reduction in pressure. It should be noted that both conditions are temporary and not harmful. If, however, either of these conditions persist, please contact the Public Works Department at 781-455-7550.

Needham Water and Sewer appreciates your patience as we work to improve the quality of drinking water throughout the town
