Water Main Flushing Program

During March 2012 , crews will be working on Great Diamond, Little Diamond and Peaks Island, Monday through Friday, 7:00 a.m. to 3:30 p.m.

The Portland Water District flushes water mains from April - October.   In an effort to reduce customer inconveniences, crews will work from 8:00 p.m. to 6:00 a.m., Sunday through Thursday night. 

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.
