Hydrant Flushing Schedule

Hydrant flushing will begin the week of March 20 in Montgomery and Upper Dublin Townships. Hydrants that have not yet been flushed are red on this map; hydrants that have been flushed are green. The areas to be flushed are highlighted in purple. Zoom in or out on the map using the + or - on the lefthand side of the map. This interactive map will be updated weekly.

Flushing in the main system will be done between the hours of 8:00 a.m. and 4:00 p.m., Monday through Friday, beginning on March 20. Affected residents will be notified in advance by phone. Flushing in our Warrington system will take place in the fall.

Annual system-wide flushing is essential for the Authority to maintain the highest level of water quality. Flushing hydrants is an important preventive maintenance activity that ensures hydrants are operational and that adequate water flow will be available if needed for firefighting. Flushing also removes sediment that naturally accumulates in water pipes. Removing the sediment maintains the high quality of the water we provide to you.

When hydrant flushing occurs in your neighborhood, you may notice discolored water coming from your faucet. If this happens, simply run your cold water tap for three to five minutes. If possible run water from a bathtub or other fixture without an aerator. If the water is still discolored, wait about 30 minutes and run the water again. This temporary discoloration only affects the appearance of the water – it does not cause a health or safety risk. While the water is safe to drink, you should avoid washing laundry during scheduled flushing times, as the flushed sediment could discolor white clothing. Wait until the water runs clear at the tap, then wash a load of dark clothes first. You should also avoid using hot water until the cold water runs clear.

If problems persist, please call our Customer Service department at 215-699-4836 between 8:00 a.m. and 4:00 p.m. Monday - Friday.
