Drought Watch Issued by NYS Department of Environmental Conservation…

The NYSDEC has issued a drought watch for all of New York.  Please take steps to conserve water whenever possible and adhere to the voluntary lawn irrigation restrictions previously issued by WJWW.  Please click here for details regarding the Drought Watch and water conservation tips.

Important Notice – Voluntary Lawn Irrigation Restrictions

The recent hot, dry weather has resulted in high water use primarily due to the increased use of residential automatic irrigation systems during early morning hours.   This situation is stressing our water system in terms of pressure and possibly affecting our ability to meet fire protection and normal domestic uses.

In order to lessen the demand during the early morning hours, we are asking residential customers that have irrigation systems and contractors that service those systems to set the controls to operate every other
day using a simple odd/even approach:

  • House addresses ending in an even number can water on even numbered calendar days, but not from 10:00 a.m. to 4:00 p.m.
  • House addresses ending in an odd number can water on odd numbered calendar days, but not from 10:00 a.m. to 4:00 p.m.

As a precaution, this odd/even approach will continue through September 30th.

We are also encouraging the use of “smart controls” for irrigation systems so that depending on precipitation, temperature, soil moisture and other factors, irrigation water is conserved, used efficiently and not wasted.  Please speak to your irrigation contractor about “smart controls.”

Voluntarily taking these steps should reduce the possibility of mandatory irrigation restrictions.

Thank you for your cooperation.

Meter Upgrade Initiative…

WJWW is in the process of upgrading the remaining meters in its system that require manual meter reads to meters that can be read by a vehicle based system and or fixed base system.  These new meters will improve the efficiency of the meter reading process, reduce the number of estimates and eventually help with more rapid detection of leaks that can result in costly water bills.   Scheduling of appointments for the first phase of this project is now taking place for the Town of Mamaroneck.  For further information or questions, please call (914) 698-3500 to speak to a WJWW service department representative.

What’s In Our Drinking Water…

WJWW publishes and mails annually to all of its customers, a water quality report which provides a wide variety of information about the WJWW system including analytical testing results.  The water quality report is also available in its entirety on this website (See navigation sidebar to left). To access the “Analytical Testing Results” section of the water quality report directly, click here.  

Unauthorized Solicitations for Payment of Water Bills:

Please be advised that unauthorized individuals have been demanding payment of water bills over the phone under threat of discontinuance of water service.  If you receive such a call, do not provide the caller with any financial information, but do contact your local Police and the Westchester Joint Water Works.

WJWW Rye Lake Emergency Generator Project

Improvements to the Westchester Joint Water Works (WJWW) water pumping station/treatment facilities at 900 Lake Street in the Town of Harrison, New York involving the purchase and installation of new emergency standby generators is being financed by the Drinking Water State Revolving Fund (DWSRF).  The DWSRF is administered by the NYS Department of Health and the NYS Environmental Facilities Corporation with joint funding from the U.S. Environmental Protection Agency and New York State. 

This project is intended to mitigate the impact of primary electrical power failures, due to storms or other causes, by providing additional emergency back-up electrical power to maintain uninterrupted operations at water pumping/treatment facilities for one of two primary water sources for WJWW, thus benefitting the community members served by the WJWW water system.  DWSRF programs operate around the country to provide states and communities the resources necessary to maintain and improve the infrastructure that protects our valuable water resources nationwide.

Please Take Note…

Irrigation Association of New York…

The WJWW is a proud member of the IANY, a great resource for those with irrigation systems.  Please remember to have your irrigation system checked for leaks when it is activated this Spring to avoid costly water bills and don’t forget that your irrigation system must have in place an approved, testable backflow prevention device (if you’re not sure or don’t have a backflow prevention device installed and on file with WJWW, call 914-698-3500).  For irrigation related water saving tips form the IANY ... click here.

Protecting Our Public Water Supply…

Due to the potential for contamination of the public water supply system, please be advised that Federal, State and WJWW regulations require that you have a certified and tested backflow prevention device(s) in place if you currently have or plan to install systems/devices, in your home or on your property, including but not limited to the following: lawn/garden irrigation system, fire suppression system, fire hydrant, swimming pool, fountain, private well.  For New York State Department of Health regulation click here.

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.
