Fall 2014 Hydrant Flushing – What to Expect:

Beginning in early November and ending prior to the Thanksgiving holiday, residents may observe WJWW crews working at fire hydrants and allowing water to run into the street.

While it may appear that this runs counter to our water conservation philosophy, the periodic “flushing” of fire hydrants is an important preventative maintenance activity that helps to insure the integrity of the water system and to provide the highest quality water to our customers. More specifically, hydrant flushing serves the following purposes:

•Flushes sediments from water main pipes, thus enhancing water quality;

•Verifies that fire hydrants and valves are working properly and that ample water flow is available for firefighting needs;

•Aids in determining weaknesses in water pipes and related fittings and valves.

Hydrant flushing will be performed on weekdays around the clock and will begin in the Town/Village of Harrison and then progress through the Village of Mamaroneck, Town of Mamaroneck, Springdale Road area of the City of New Rochelle and the Greenhaven section of the City of Rye.

Regular updates related to hydrant flushing activities will be posted on the WJWW website and provided via phone and e-mail through our notification system.

Residents in the immediate vicinity of hydrant flushing activities may temporarily experience cloudy/discolored water, the discoloration is harmless and generally consists of precipitates that do not affect the safety of the drinking water. If you notice that your water is discolored, it can be cleared by running cold water from a faucet at the lowest level within your home for a few minutes.

While the discoloration lasts, do not use hot water or do laundry as this could cause sediment to accumulate in your hot water system and/or cause clothing to become discolored -please note that WJWW is not responsible for any damage resulting from the use of discolored water.

If you experience discolored water conditions that last for more than a day, please contact WJWW at 914-698-3500.

WJWW thanks you for your patience and understanding as we perform the important task of hydrant flushing to help insure that you have reliable, high quality water service.  Click here for updates and schedules.

Please Remember...

Important Notice

The Water Works will be turning off Seasonal Water connections in the Village and Town of Mamaroneck, Town/Village of Harrison, and the Greenhaven section of Rye during the weeks of October 14th and October 27th. 

In order to avoid potential backflow into the water supply system as well the reverse flow of compressed air (which can cause ruptured plumbing in neighboring properties), it is essential that your irrigation company not blow out your seasonal water line until the Water Works has turned off your water at the curb stop.

Homeowners will be notified when their service has been turned off. 

If you have any questions, please contact us by email at service@wjww.com or by calling 914-698-3500.

Protecting Our Public Water Supply…

To comply with current regulations, the backflow prevention device(s) must be:

  • Approved by WJWW for water services of any size with additional approval from the Westchester County Department of Health for water services of greater than 2 inches in size;
  • Inspected by WJWW for water services of 2 inches and less;
  • Inspected by design engineer for water services greater than 2 inches;
  • Tested successfully by a certified backflow tester within the past 12 months (Backflow devices must be tested annually and the results submitted to WJWW

If you as a residential customer are unsure as to whether your property is in compliance with this regulation, please contact WJWW as soon as possible to have your situation assessed so as to avoid potential liability, violations and penalties.

Commercial/Industrial/Institutional customers please take note that backflow prevention is always required and regulations pertaining to your facilities/processes can involve many more factors, so please contact the WJWW with any questions regarding your particular situation.

Westchester Joint Water Works Asks Residents and Office Customers to Check Their Irrigation Systems, Use Water Wisely and “Fix a Leak”

Westchester Joint Water Works (WJWW), as well as the Town of Harrison, The Town of Mamaroneck and the Village of Mamaroneck are again encouraging their residents and commercial customers to check their irrigation systems, use water wisely and look for and fix any leaks in homes and office buildings. Below are simple facts that homeowners should be aware of regarding irrigation systems and leaks in household fixtures.

All WJWW customers with irrigation systems are reminded of the following:

The system requires approval from WJWW and must be installed by a qualified contractor and needs to have a backflow prevention device.
  • The system must be properly winterized in the fall before the onset of cold-freezing weather.
  • The system and the backflow device must be properly tested for leaks before the start of the irrigation season; and
  • The systems should have its own sub-meter to help determine how much water is actually used for irrigation.
  • An irrigation system should be checked each spring before use to make sure it was not damaged by frost or freezing.
  • An irrigation system with pressure set at 60 pounds per square inch that has a leak 1/32nd of an inch in diameter (about the thickness of a pen point) can waste about 6,300 gallons of water per month.
  • To ensure that your in-ground irrigation system is not leaking water, consult with an irrigation specialist who has passed a certification program focused on water efficiency.
  • Check your garden hose for leaks at its connection to the spigot. If it leaks while you run your hose, replace the nylon or rubber hose washer and ensure a tight connection to the spigot using pipe tape and a wrench.
The Facts on Leaks:
  • Leaks can account for, on average, 10,000 gallons of water wasted in the home every year, which is enough to fill a backyard swimming pool.
  • The amount of water leaked from U.S. homes could exceed more than 1 trillion gallons per year. That's equivalent to the annual water use of Los Angeles, Chicago, and Miami combined.
  • Ten percent of homes have leaks that waste 90 gallons or more per day.
  • Common types of leaks found in the home include leaking toilet flappers, dripping faucets, and other leaking valves. All are easily correctable.
  • Fixing easily corrected household water leaks can save homeowners more than 10 percent on their water bills.
  • Keep your home leak-free by repairing dripping faucets, toilet valves, and showerheads. In most cases, fixture replacement parts don't require a major investment and can be installed by do-it-yourselfers.
  • The vast majority of leaks can be eliminated after retrofitting a household with new fixtures and other high-efficiency appliances.
Leak Detection:
  • A good method to check for leaks is to examine your winter water usage. It's likely that a family of four has a serious leak problem if its winter water use exceeds 12,000 gallons per month.
  • Check your water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, you probably have a leak.
  • One way to find out if you have a toilet leak is to place a drop of food coloring in the toilet tank. If the color shows up in the bowl within 15 minutes without flushing, you have a leak. Make sure to flush immediately after this experiment to avoid staining the tank.
Faucets and Showerheads:
  • A leaky faucet that drips at the rate of one drip per second can waste more than 3,000 gallons per year.
  • Leaky faucets can be reduced by checking faucet washers and gaskets for wear and replacing them if necessary.
  • A showerhead leaking at 10 drips per minute wastes more than 500 gallons per year. That's enough water to wash 60 loads of dishes in your dishwasher.
  • Most leaky showerheads can be fixed by ensuring a tight connection using pipe tape and a wrench.
  • If your toilet is running constantly, you could be wasting 200 gallons of water or more every day.
  • If your toilet is leaking, the cause is most often an old, faulty toilet flapper. Over time, this inexpensive rubber part decays, or minerals build up on it. It's usually best to replace the whole rubber flapper—a relatively easy, inexpensive do-it-yourself project that pays for itself in no time.
  • If a family of four replaces its older, inefficient toilets with new one, it could save more than 16,000 gallons per year. Retrofitting the house could save the family approximately $2,000 in water and wastewater bills over the lifetime of the toilets.
