Water Department to begin hydrant flushing on Monday, October 16th

October 16, 2017

The Water Department will begin their twice annual routine hydrant flushing of the City’s 190 miles of water mains to remove sediment buildup on Monday, October 16th. 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 8:00 p.m. and midnight, 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, the water remains safe for residents to drink.
