Water Main Flushing

Water Main Flushing
Hydrant flushing is how Portland cleans the inside of its drinking water pipes and maintains excellent drinking water quality.

The Portland Water Bureau is conducting flushing of water mains. Flushing is routine maintenance to clean the network of pipes and improve water quality. It forces high-speed water through pipes to remove sediments, and brings fresh water into the pipes to improve water quality. Flushing crews temporarily close valves to isolate sections of pipe, and water is directed through an open fire hydrant. Flushing usually occurs Monday through Friday, between 8:00 a.m. and 1:30 p.m.

Residents in the immediate vicinity of flushing may notice temporarily discolored water and lower than normal water pressure. The discoloration does not pose a health risk. However, limit water use and avoid using hot water or running the washing machine or dishwasher until flushing is complete. If you experience some discoloration in your water from nearby flushing, run the water at one tap for 5 minutes to see if it clears. If it does not clear, wait an hour and try again. When the water runs clear, flush any taps where discolored water was present.
