[Adopted by L.L. No. 5-1992 (Sec. 640 of the 1996 Code)]
A.
The purpose of this article is to safeguard potable public 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 article 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 Dryden, New York, to comply with the requirements
of New York State Sanitary Code, Part 5, Section 5-1.31, which said
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 article by reference as if more fully stated.
B.
It is further the intent of the Village to comply with future changes,
addendums, and guidelines to said code and manual.
As used in this article, the following terms shall have the
meanings indicated:
A check valve that seats readily and completely. It must
be carefully machined to have free moving parts and assured watertightness.
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.
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 acceptable as a complete assembly.
Reference is hereby made to the "Technical References of the Environmental
Health Manual" as published by the New York State Department of Health.
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 acceptable
as a complete assembly. Reference is hereby made to the "Technical
References of the Environmental Health Manual" as published by the
New York State Department of Health.
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, but in no case
less than one inch.
Any water supply approved by the New York State Department
of Health.
An individual who has successfully completed a New York State
Department of Health approved course in the testing of back flow prevention
devices and has been issued a certificate by the New York State Department
of Health.
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 system containing water or substance that is not or
cannot be approved as equally safe, wholesome and potable for human
consumption.
Any water supply on or available to the premises other than
an approved public water supply.
A vacuum breaker which can only be used for internal plumbing
control and, therefore, is not acceptable as a containment device.
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 article and all other required regulations and
laws.
A.
Where protection is required. All water system users within the Village
of Dryden shall be required to maintain a degree of protection commensurate
with the degree of hazard regardless of whether the hazard is immediate
or potential. To that extent, the Cross-Connection Control Manual
published by NYSDOH shall be used as a guide to determine where protection
is required. It shall be the responsibility of the water user to provide
and maintain such required protection devices, and such devices shall
be of a type acceptable to the New York State Department of Health.
B.
Type of protection. The protective device required shall depend on
the degree of hazard as tabulated below:
(1)
At the service connection to any premises where there is a supplementary
water supply handled in a separate piping system with no known cross-connection,
the public water supply shall be protected by an acceptable reduced
pressure zone device.
(2)
At the service connection to any premises on which a substance that
would be objectionable (but not necessarily hazardous to health if
introduced into the public water supply) is handled so as to constitute
a cross-connection, the public water supply shall be protected by
an acceptable double-check valve assembly.
(3)
At the service connection to any premises on which a substance of
unusual toxic concentration or danger to health is or may be handled,
the public water supply shall be protected by an air gap separation
or an acceptable reduced pressure zone backflow prevention device.
If an air gap is installed, it shall be located as close as practical
to the water meter, and all piping between the water meter and receiving
tanks shall be entirely visible. A reduced pressure zone device, when
installed, shall be located as close as possible to the property line.
(4)
At the service connection to any sewage treatment plant or sewage
pumping station, the public water supply shall be protected by an
acceptable reduced pressure zone backflow prevention device and it
shall be located as close as possible to the property line.
C.
Frequency of inspection of protective devices. It shall be the duty
of the water user on any premises where backflow protective devices
are installed to have competent inspections made at least once a year,
or more often in instances where successive inspections indicate repeated
failure. Devices shall be repaired, overhauled or replaced at the
expense of the water user whenever they are found to be defective.
These tests shall be performed by a qualified backflow prevention
device tester and all test results will be provided to the Village
within 72 hours after the test is made. Records of such tests, repairs
and overhaul shall also be kept and made available to the water user
and the local Health Department upon request.
A.
No water service connection to any premises shall be installed or
maintained by the water user, unless the water supply is protected
as required by this article and such other applicable local, state
and federal laws, rules and regulations.
B.
Service of water to any premises may be discontinued by the Village
if a backflow prevention device required by this section and regulations
is not installed, tested and maintained; if any defect is found in
an installed backflow prevention device; if it is found that a 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 conditions or defects are corrected.
C.
Village Water Department personnel shall be allowed access to premises
of water users for the purpose of determining the need for and compliance
with the provisions of this article. If any facility served by the
Village's water system denies a Village Water Department person access
to their premises for the purposes of determining if protection to
the public water system is necessary, then the maximum protection
condition shall be imposed with the requirement that the number of
devices shall equal the number of service lines.
D.
Failure to comply with any of the provisions of this section shall
be deemed a violation and the violator shall be punished as set forth
on the Village of Dryden Fine Schedule, which Fine Schedule may be
established by resolution and thereafter amended from time to time
by resolution of the Village Board of Trustees.
[Amended 4-10-2014 by L.L. No. 3-2014]
The Board of Trustees of the Village of Dryden is authorized
to adopt such rules and regulations as may be appropriate to carry
out the purpose and intent of this article.
A.
The provisions as set forth herein shall apply immediately upon the
effective date of this article to all water users commencing or renewing
service on or after that date. No building permit for new construction
shall be issued without compliance with the provisions of this article
and such other applicable local, state and federal laws, rules and
regulations.
B.
The provisions as set forth herein shall apply six months after the
effective date of this article to water users who have commenced service
prior to the effective date of this article. Notwithstanding the above,
the Village may require immediate compliance with all provisions of
this article (and may terminate service) in the event a hazard of
contamination of the public water system from the facility of an existing
user is determined to exist.
