    Water Main Flushing Schedule
    Water main flushing is a necessary maintenance procedure, scheduled once a year. Flushing is performed on normal workdays, between midnight and 4 a.m. Water pressure variations or discolored water conditions may occur.  To avoid inconvenience, check the water before doing laundry and keep water in the refrigerator for drinking and cooling. Discolored water can also result from street construction or water main work being done in the area.  Any disturbance to the water main, including the flushing of an open hydrant, may cause pipe sedimentation to shift, resulting in rusty brown-colored water. The settling time will vary, dependent upon the size of your street's water main. It is recommended to run your cold water for a number of minutes to flush the line.

    Surface Water Treatment Rule

    Disinfection Treatment and Public Notification

    1st Quarterly Tier 2 Violation Notice 


    Westchester County Water District (WCWD) #1 Failure to Meet Treatment Requirements

    Our water system is in violation of Federal drinking water requirements, specifically the Safe Drinking Water Act (SDWA) and the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR). The White Plains Orchard Street Pumping Station Ultraviolet (UV) Facility has been completed, accepted and placed into service on June 24, 2017 and is providing compliant water achieving the court ordered Consent Order date.  During this quarter, the Orchard Street Pumping Station UV Facility has been in continuous service from January 1 to March 31, 2018 providing compliant water. Until the Central Avenue Pumping Station UV facility was completed and accepted, the Orchard Street Pumping Station and UV facility was operated continuously to provide as much compliant water as possible to the City of White Plains. During the morning and evening hours when water demands exceed the capacity of the Orchard Street Pumping Station the water is not in compliance. The Central Avenue Pump Station UV Facility was completed, accepted and placed into service on March 13, 2018 and is providing compliant water achieving the court ordered Consent Order date. From March 13 to March 31, 2018, White Plains received compliant water from both UV Facilities.

    Water is supplied by WCWD#1 through the Kensico-Bronx Pipeline (KBP). The northern KBP is supplied from the Kensico Reservoir by gravity flow.  The southern section is supplied from Shaft 22 of the Delaware Aqueduct.  Currently, WCWD#1 provides potable water through the KBP to the District member communities of the Cities of White Plains, Yonkers, and Mount Vernon, and the Village of Scarsdale.  In addition, the City of White Plains supplies water to a portion of the Town of North Castle, an out-of-District user, through a connection contained within the City of White Plains system. The Town of North Castle has a UV system which provides compliant water to the Town of North Castle.

    The U.S. Environmental Protection Agency (USEPA) requires certain public water systems utilizing surface water to be in compliance with the Long-Term 2 Enhanced Surface Water Treatment Rule. The New York City Department of Environmental Protection (NYCDEP) has completed construction of the Catskill-Delaware Water UV Disinfection Facility which was implemented in response to the USEPA LT2ESWTR.  This Rule requires disinfection that targets cryptosporidium.  The 2 billion gallon per day facility provides UV disinfection of water that is compliant with LT2ESWTR. This water, which is also disinfected with chlorine, is provided to connections in the southern portion of WCWD#1 from Shaft 22 of the Delaware Aqueduct which supplies all of Mount Vernon and portions of the City of Yonkers.

    Water taken by the District directly from the Kensico Reservoir is disinfected with chlorine, which provides virus inactivation; however the District’s utilization of chlorination is not sufficient to bring the District into compliance with the LT2ESWTR’s treatment requirements for cryptosporidium, and therefore that water is not in compliance with the Rule as described above.

    Although this situation does not require that you take immediate action, as our customers, you have the right to know about compliance with drinking water requirements, what you should do, and what we are doing to correct this situation.

    Notification Public and State notifications are required to the violation noted above.

    What should I do?

    • There is nothing you need to do at this time. You do not need to boil your water or take other corrective actions.  However, if you have specific health concerns, consult your doctor.
    • If you have a severely compromised immune system, have an infant, are pregnant, or are elderly, you may be at increased risk and should seek advice from your health care providers about drinking this water.  General guidelines on ways to lessen the risk of infection by microbes are available from EPA’s Safe Drinking Water Hotline at 1-800-426-4791.

    What does this mean?

    A portion of the water you have received from WCWD#1, as described above, is in violation of the Long Term 2 Enhanced Surface Water Treatment Rule and, therefore, we are required to include the following statement in this notice:

    *Inadequately treated water may contain disease-causing organisms. These organisms include bacteria, viruses, and parasites which can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.*

    These symptoms, however, are not caused only by organisms in drinking water, but also by other factors.  If you experience any of these symptoms and they persist, you may want to seek advice from your healthcare provider. EPA/CDC guidelines on appropriate means to lessen the risk of infection by cryptosporidium, giardia and other microbial pathogens are available from the Safe Drinking Water Hotline (800-426-4791).

    The WCWD#1 Chlorination Systems are in operation providing treatment for giardia, bacteria and viruses. Test results of samples collected on a weekly basis from April 22, 2015 thru March 15, 2018 samples for cryptosporidium and giardia from the source water have not indicated the presence of cryptosporidium or giardia in the drinking water during this period except as follows:

    The December 17, 2016 and January 11, 2018 cryptosporidium results were 0.02 cycts/liter well below the action level of 4 cysts/liter and require no action based on the approved action plan.

    The January 24, February 14, March 7, May 4, December 21, 2017 and February 8 and March 1, 2018 results indicate minor presence of giardia, less than 0.06 cysts/liter.

    What has been and is being done?

    Westchester County has implemented a Cryptosporidium action plan, which includes weekly monitoring of water taken from the Kensico Reservoir for the presence of cryptosporidium. The enhanced monitoring will continue until the Local UV Treatment Systems described below are completed.  The weekly monitoring results will be published on the Westchester County website at  Select Departments, then Environmental Facilities, then Facilities on the top right tool bar, then County Water District #1 on the drop down.

    To provide UV disinfection treatment for the northern section of the KBP, two new independent UV disinfection facilities have been constructed at separate locations along the KBP.  Two facilities (rather than one single facility) are required due to hydraulic conditions inherent to the existing gravity-driven supply systems.  Both UV facilities are in White Plains.  One UV facility is located at the Orchard Street Pumping Station and the other UV facility is located at the Central Avenue Pumping Station.

    For more information, please contact Anthony Della Valle at (914) 813-5477 or .

    *Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.*
