The City of Hagerstown's annual hydrant flushing program is about to begin.
The 71,000 people served by the city water system should check their water supply before washing clothes during periods when neighborhood hydrants are being flushed, said Gene Walzl, Water Department manager.
The city notifies residents through The Herald-Mail newspapers when their neighborhood hydrants will be flushed, he said.
The flushing program cleans out rust and other particles, Walzl said. It also helps maintain the quality of water and brings freshly chlorinated water into the pipes, he said. Chlorine disinfects the water.
The sole employee in charge of the flushing operation begins with hydrants near the water sources and works out, Walzl said. The water sources are the R.C. Willson Water Treatment Plant near Williamsport and the William M. Breichner Water Treatment Plant near Smithsburg.
