Twin Lakes Water Works Corporation

P.O. Box 258, South Salem, New York 10590

General Information

The Twin Lakes Water Works Corporation (TLWW) is owned by 63 Twin Lakes Village residents, who purchased shares and the water works from the previous absentee owner in 1966. With this purchase we gained control over and responsibility for the level of service, the water rates and the water quality, as well as the obligation to comply with state requirements. The TLWW shares are assigned to the house and automatically transfer with the sale of the house. In Twin Lakes Village, 90 homes are served by the water works, and 5 homes have their own wells and are exempt from TLWW regulations. (Homes on Oscaleta Road are not supplied water by the TLWW.)

The water system is regulated by Part 5 of the New York State Sanitary Code, which is monitored and enforced by the Westchester County Health Department. We retain a certified operator to ensure compliance with all regulations. As required, we test for bacteriological contamination monthly, and those samples have always met these standards. We also test for contaminants in the water supply, as required by the state. We have tested for organic and inorganic chemicals, nitrates, nitrites, lead and copper. Results are shown on the annual water quality report. In January of 1999 the NYS Health Department required the TLWW to add an orthophosphate product as a corrosion inhibitor. This forms a protective barrier between the flowing water and the pipe’s surface and serves to lower the lead and copper concentrations below the required limits.

The water for the 90 homes comes from two wells, and is chlorinated and pressurized for distribution. In 2011, 4.8 million gallons, averaging about 13,000 gallons per day, were used by our community. Our capacity is adequate for normal domestic household use, but if abused we can encounter poor water pressure and shortages. This is why we have restrictions on water use. Compliance with these regulations is essential and will help ensure an adequate water supply for you and your neighbors. County restrictions apply to all residents, including TLWW users. See for additional information.

We remind you of the following restrictions on water use:

  1. Only HAND HELD hoses may be used for outside watering. (Please also inform any maintenance services you use of these limitations.)
  2. The use of any kind of sprinkler, soaking hose or other watering device is strictly prohibited.
  3. Filling swimming pools, skating rinks, or any other large receptacles for storing or holding water is not allowed.
  4. Water cooled air conditioners are not allowed.
Violators are subject to restriction of service. We appreciate your understanding of these rules and your cooperation with them.

Why are costs are so low

Residents volunteer to perform the daily system monitoring and chlorine testing that is required by the state. In addition, the officers and directors manage the administration and basic system operations, and arrange for professional maintenance as required. They take certification classes to enhance their professional expertise. Field production problems 24/7 on a regular basis. Routinely inspect and swap valves and motors. Maintain communications with the authorities, community, web, etc. The professional services provided by the generosity and expertise in our community cost other communities well over $100,000. This volunteer framework results in substantial cost savings to all users. New volunteers are needed, and you can contact any of the people listed below to find out how you can participate.

Under the provisions of Part 5 of the New York State Sanitary Code, the State Department of Health requires water companies to have a cross-connections communications program and to inform their customers of the possibility of water contamination through cross-connections. While in a residential water system like ours such contamination is relatively rare, it is important for all users to understand how cross-connections can occur, your obligation as users to avoid them, and how to prevent contamination from any cross-connections. Cross-connections are any linkage through which contaminants could possibly enter a water supply. The contaminant enters the water system through either backflow, when the pressure of the pollutant is greater than the pressure of the water supply, or back siphonage, when a loss in pressure in the water system siphons contaminants into the distribution system through a submerged inlet. Some examples help clarify the situations under which cross-connection contamination might occur. One example is someone who used a hose to fill a container of pesticide or weed killer and left the hose under the surface of the liquid. If a sufficient drop in water pressure from the supply line occurred, it is possible that the pesticide would travel back up the hose and into the house water supply. Another example is antifreeze or corrosion inhibitors in the heating system pipes of a house. If there were a drop of pressure outside the house, it is possible that the antifreeze would drain into the house water system and into the public water lines. A private well connected to the plumbing system served by public water is another example of a cross-connection. These connections are not permitted unless the public system is protected by an appropriate backflow preventer, inspected annually. Other examples could involve other chemical pollutants, such as photography chemicals, and "used" water, such as bathtubs with a spigot or a detachable spray handle which is under the level of the water in the tub. The first defense is knowledge and common sense. Once you know that cross-connection contamination can occur, you can prevent it. Always be very careful in your use of chemicals, and always have an air gap between a hose or spigot and the level of liquid in a container. If you have cross-connections in your plumbing system, you must have a containment device between your house pipes and the water system. The EPA indicates that a dual check valve supplies reliable and inexpensive protection for individual residences. Installing this device is the water system user's responsibility and expense. If you have a system with the potential for contaminating the Twin Lakes Water Works system, please contact one of the TLWW officers or directors as soon as possible. We will ensure that you are put in touch with the NY State Department of Health authorities. If you have any reason to believe that your internal piping does not comply with the local or state plumbing codes, please begin the process of bringing your home into compliance immediately. More information on the topic of cross-connections is available from the NYS Department of Health, 145 Huguenot Street, 8th floor, New Rochelle, NY 10801. Phone: (914) 813-51
