Water flushing operations to begin September 17th

September 17, 2018

Currently, the Water Division started their twice annual routine hydrant flushing of the City’s 190 miles of water mains to remove sediment buildup on Monday, September 17th. Work will not occur on the evenings of September 24th or September 25th. 

This work will occur on both public and private hydrants spanning New Castle, Rye, Greenland, Newington and Portsmouth, lasting about six to eight weeks. Between 7 p.m. and 11 p.m., Monday through Thursday, crews will open select fire hydrants, releasing water with enough velocity to carry sediment out of the pipes. While flushing can result in discolorations to tap water, customers can use cold water to flush their lines and the water remains safe to drink.

For questions regarding water supply and quality, please contact Deputy Public Works Director Brian Goetz at bfgoetz@cityofportsmouth.com or 603-766-1420.
