Hydrant Flushing Facts & Frequently Asked Questions

Why does WJWW perform hydrant flushing?

Hydrant flushing is the quick release of water from fire hydrants.  It’s a controlled procedure that is vital to the general maintenance of the WJWW water distribution system.  It ensures adequate water flow is available to fire fighters, residents, and businesses.  It also improves water quality by clearing iron and other mineral deposits from the water mains.

What are the effects of hydrant flushing?

Hydrant flushing helps ensure water quality and helps avoid random bouts of rusty water if there is a high demand for water, caused by a major firefighting effort or water main break.

During the flushing of a hydrant, some customers may notice reduced water pressure and flow.

Why is my water rust/tea-colored from the hydrant flushing?  Is the water safe?

Sometimes hydrant flushing can make the water temporarily appear rust-colored because the iron and other mineral deposits in the water mains get stirred up.  There is no health hazard associated with discolored water.  Water is safe to use and consume during hydrant flushing, however it may stain laundry.

How come my water is discolored, but my neighbor didn’t notice my discoloration? 

If the water inside a home or business is turned on while hydrant flushing is going on, discolored water may enter your plumbing.  If a neighbor did not use water during the day, they most likely will not notice any discoloration. 

My water is discolored.  What should I do?

Wait until flushing has subsided in your area then run a cold water tap until the water runs clear. Remember rust colored water is safe, but it may stain laundry.  If this happens, keep clothes wet and treat them with stain remover provided by WJWW.

WJWW offers a stain removal product at no cost to their residents and can be picked up at 1625 Mamaroneck Ave Mamaroneck, NY 10543.

If you notice the water flushing crew is near your property, refrain from using water, and delay washing clothes as much as possible.
