The Water Division will start their twice annual routine hydrant flushing of the City’s 190 miles of water mains to remove sediment buildup on Monday, April 15th. 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.
