This chapter shall be known and may be cited
as "Local Law No. 2 of the year 1996 of the Village of Hammondsport,
Steuben County, New York."
The purpose of this chapter is to safeguard
potable water supplies from potential contamination by preventing
backflow from a water user's system into the public water system.
It is the intent of this chapter to recognize that there are varying
degrees of hazard and to apply the principal that the degrees of protection
should be commensurate with the degrees of hazard. Further, it is
the intent of the Village of Hammondsport, New York, to comply with
the requirements of New York State Sanitary Code, Part 5, Section
5-1.31, which section mandates the requirement that the supplier of
water protect their water system in accordance with procedures acceptable
to the Commissioner of Health. These mandated requirements are as
set forth in the Cross Connection Control Manual published by the
New York State Department of Health (NYSDOH) and to that extent the
terms, conditions and provisions of the New York State Sanitary Code,
Part 5, Section 5-1-31, and the Cross Connection Control Manual are
incorporated in this chapter by reference as if more fully stated.
As used in this chapter, the following terms
shall have the meanings indicated:
AIR GAP SEPARATION
A physical break between a supply pipe and a receiving vessel.
The air gap shall be at least double the diameter of the supply pipe,
measured vertically above the top rim of the vessel, in no case less
than one inch.
APPROVED CHECK VALVE
A check valve that seats readily and completely. It must
be carefully machined to have free moving parts and assured water
tightness. The face of the closure element and valve seat must be
bronze, composition or other noncorrodible material which will seat
tightly under all prevailing conditions of field use. Pins and bushings
shall be of bronze and other noncorrodible, nonsticking material,
machined for easy dependable operation. The closure element shall
be internally weighted or otherwise internally equipped to promote
rapid and positive closure in all sizes where this feature is obtainable.
APPROVED DOUBLE CHECK VALVE ASSEMBLY
Two single independently acting check valves, including tightly
closing shutoff valves located at each end of the assembly and suitable
test connections. This device must be approved as a complete assembly.
APPROVED REDUCED PRESSURE ZONE DEVICE
A minimum of two independently acting check valves, together
with automatically operated pressure differential relief valve located
between the two check valves. In case of leakage of either check valve,
the differential relief valve, by discharging to the atmosphere, shall
operate to maintain the pressure between the checks at less than the
supply pressure. The unit must include tightly closing shutoff valves
located at each end of the device, and each device shall be fitted
with properly located test cocks. This device must also be approved
as a complete assembly.
AUXILIARY SUPPLY
Any water supply on or available to the premises other than
the approved public water supply.
CERTIFIED BACKFLOW PREVENTION DEVICE TESTER
An individual who has successfully completed a New York State
Department of Health approved course in the testing of backflow prevention
devices and has been issued a certificate by the New York State Department
of Health.
CROSS CONNECTIONS
Any unprotected connection between any part of a water system
used or intended to be used as a supply of water for drinking purposes
in a source or systems containing water or substance that is not or
cannot be approved as equally safe, wholesome and potable for human
consumption.
WATER SUPERVISOR
The consumer or a person on the premises charged with the
responsibility of complete knowledge and understanding of the water
supply piping within the premises and for maintaining the consumer's
water system free from cross connections and other sanitary defects,
as required by this chapter and all other required regulations and
laws.
This chapter shall take affect upon filing with
the New York State Department of State.
