The purpose of this article is to safeguard
potable water supplied from potential contamination by preventing
backflow from a water user's system into the public water user's system
and to comply with the requirements of the New York State Sanitary
Code, Part 5, Section 5-1.31.
A.
Check valves or backflow-prevention devices conforming
to the most current requirements of the New York State Department
of Health and the Westchester County Department of Health shall be
installed by the owner of those systems pursuant to the rules of those
Departments in force at the time of the installation.
B.
Certificates of occupancy shall not be issued by the
Building Inspector for new or modified/renovated/rehabilitated structures
with hazardous systems without a letter from the Superintendent of
Public Works or his/her designee stating that the check valves or
backflow-prevention devices have been installed.
C.
The cost to install the check valves or backflow-prevention
devices shall be borne by the owner of the property.
Any preexisting systems that do not embody cross-connection
control devices shall be upgraded so as to comply with the current
requirements of the New York State Department of Health and the Westchester
County Department of Health within 60 days following the service of
notice by certified mail to install check valves or backflow-prevention
devices.
The testing of cross-connection control devices
shall be performed on an annual basis by the owner of any system requiring
the same, and the cost of such testing shall be borne by the owner
of the system. The testing procedures shall conform to the requirements
of the New York State Department of Health and the Westchester County
Department of Health.
The Superintendent of Public Works or his/her
designee shall develop a manual which shall provide the cross-connection
program requirements for the Village of Tarrytown. The Superintendent
of Public Works shall incorporate the requirements of the New York
State Department of Health and the Westchester County Department of
Health.
In addition to the penalties provided for in Chapter 1, Article II, the service of water to any premises may be discontinued by the water supplier if check valves or backflow-prevention devices required by this article and regulations adopted pursuant thereto are not installed, tested and maintained; if any defect is found in an installed check valve or backflow-prevention device; if it is found that a check valve or backflow-prevention device has been removed or bypassed; or if unprotected cross-connections exist on the premises, and service will not be restored until such condition or defects are corrected.
