Beginning March 18, 2024, North Wales Water Authority will begin our annual system-wide flushing. Flushing is essential for the Authority to maintain the highest level of water quality, which will be done between the hours of 8:00 a.m. and 4:00 p.m.
You may notice discolored water when flushing is in your area…this is expected and is not harmful. Simply let the cold water run from your taps until it becomes clear. If possible, run water from a bathtub or other fixture without an aerator. Should problems persist, please call NWWA’s Customer Service department at 215-699-4836 between 8:00 a.m. and 5:00 p.m. Monday – Thursday and 8:00 a.m. and 4:00 p.m. on Friday.
Please refer to the interactive map below to monitor the progress of the hydrant flushing. As each hydrant is serviced, its indicator will change from red to green, allowing you to easily track completions.
