WJWW received two Westchester County Department of Health (WCDOH) violations.  The first violation was that one (1) of the two (2) pumps for the backup tablet chlorinators, at the Larchmont Pump Station/Treatment Plant was found to be leaking and not working properly and WJWW was directed by WCDOH to replace this backup tablet chlorinator.     In response to this violation, in March 2011, WJWW received approval   and installed  the new backup tablet chlorinator, which corrected this violation.   The second violation, a backflow prevention device was found to be bypassed at the Larchmont Pump Station.  Not having a backflow prevention device installed can allow for contaminated water to go into WJWW’s system.   In response to this violation, WJWW installed a backflow prevention device in the correct location as directed by the WCDOH in March 2011.    Even though these violations were not an emergency or health risk, as our customers, you have the right to know what happened and what we did  to correct this situation.  If you have any questions or require additional information, please call Westchester County Health Department at (914) 813-5000.

Variances, Exemptions, Administrative or Judicial Orders under the federal Surface Water Treatment Rule, provide that surface supplies, such as that used by the City of New York, require filtration unless certain rigid requirements can be met.  New York City's filtration avoidance for its Catskill-Delaware supply was renewed for a 10 year period in July 2007 (for further information visit http://www.nyc.gov/html/dep/pdf/wsstate08.pdf.) This filtration avoidance declaration will remain in effect until July 2017 and applies to the WJWW Shaft 22 connection.

Despite the fact that the WJWW’s Rye Lake connection derives its water from the Kensico Reservoir, which meets all filtration avoidance criteria for New York State, WJWW is subject to a pending order which requires the WJWW to build a filtration plant for the Rye Lake portion of its supply.  Currently WJWW is in discussion with the State regarding acceptable alternatives to the Rye Lake Filter Plant which involve alternate sources of water and the phase out of the Rye Lake intake.
