Love that dirty water: Fall flushing is here!

Sep 3, 2020

The Dartmouth Water Department will be flushing water mains all over town from September 21 through November 13 between 6 and 10 p.m.

The goal of flushing is to move water through the water mains at a high speed to loosen and remove deposits of iron and manganese that build up inside the pipes.

Flushing disturbs sediment and can result in temporarily discolored water in residents’ homes.

The water department recommends that residents avoid doing laundry and drawing hot water when water appears discolored during this time.

If water appears discolored after 11 p.m., residents should let the water run until it clears.

Homeowners may experience reduced water pressure during flushing operations due to water being diverted to the hydrants. This is temporary.

If water pressure does not return to normal after 11 p.m., residents should notify the water department at (508) 999-0742.

Flushing dates and locations will be available on the Town of Dartmouth’s website at
