Water Main Flushing
The Portland Water District typically flushes water mains from April - October. The 2020 flushing program began May 13.
Maintenance flushing activities generally occur during normal business hours, Monday through Friday from 6:00 a.m. to 3:30 p.m.
This maintenance activity uses a high velocity flow of water in the opposite direction of natural flow to keep the water mains clean and fresh. During flushing, any sediment that may be in the mains is released out the hydrants.
Customers may notice short periods of water discoloration; however, this program is essential to maintain water quality and public health. If customers experience any change in water quality following maintenance activities or have security concerns regarding Portland Water District employees, please call 761-8310.
