The District’s annual Water Main Flushing Program is typically between February and May each year. We flush our system to remove sediment from water mains throughout the District. The Program is part of the District’s on-going water quality and system maintenance work.
The work involves little or no interruption of service; although a slight discoloration of the water, and drop in water pressure, may occur in areas where flushing is underway.
Crews place flushing signs in the neighborhoods one to two days prior to flushing the area and the work is done from 7:30 a.m. to 4:30 p.m. Monday through Friday. We will post maps of the areas we are working in on this page.
Most residents will not be out of water during flushing; however, some residents in the immediate vicinity of the work may experience temporary discoloration of their water. This discoloration does not pose a health risk; however residents should check their water before washing any clothing.If you notice our crews in your neighborhood, we recommend not turning on your water between 8 a.m. and 4 p.m. unless it’s necessary. This includes not running appliances using water, such as dishwashers and washing machines. If you notice discolored water in your private system, turn on each cold water faucet and allow the water to run until it is clear again and flush each toilet two times. Please call the District Office at 503.665.4179 with questions.
