Hydrant Flushing Schedule & Map (1014 KB)
Public Services Department personnel will flush the hydrants and mains to remove accumulated sediments. Flushing does not affect the safety of the water supply. Tap water may appear cloudy or discolored immediately after flushing. If you notice cloudy or discolored water, please run your cold water until it runs clear again.
Periodic flushing is necessary to get rid of deposits that form inside the water mains. Over time, sediment builds up on the inside of water distribution pipes, narrowing the path that water can flow through to individual homes and businesses. Flushing stirs up water in the mains and forces water and sediments out. By widening the path that water can flow through the mains, the flushing program will improve water flow, to better meet the needs of the community. The flushing program also allows staff to verify that all water supply systems are working correctly such as pumps, storage tanks, mains, valves, and hydrants.
If you have scheduled construction or maintenance projects during this time, please call 3-1-1 or 269-337-8000.
