[Amended 12-19-2005 by L.L. No. 5-2005]
A. The purpose of this section is to:
(1) Protect the public drinkable water supply of the Village
of Williamsville from the possibility of contamination by isolating
within its customers' internal distribution system(s) or its customers'
private water system(s) such contaminants or pollutants which could
backf1ow in the public water supply system; and
(2) Comply with the requirements of the New York State
Sanitary Code Subpart 5, and in particular 5-1.31, and other provisions
of the New York State Department of Health (NYSDOH).
B. Responsibility. The Williamsville Water Department
(WWD) shall be responsible for the protection of all Village of Williamsville
water distribution systems from contamination due to the backflow
of the contaminants through the water service connection. If, in the
judgment of said Water Department, an acceptable backflow prevention
device is required at any Village water service connection to any
customer's premises, for the safety of the water system, the Water
Department or its designated agent shall give notice in writing to
said customer to install such acceptable backflow prevention device
at each service connection to his or her premises. The customer shall
immediately install such approved device or devices at his own expense;
and failure, refusal or inability on the part of the customer to install,
have tested and maintained said device or devices shall immediately
constitute a ground for discontinuing water service to the premises
until such requirements have been met.
C. Definitions.
(1) As indicated in this section, the following terms
shall have the meanings indicated:
ACCEPTABLE BACKFLOW PREVENTION DEVICE
An acceptable air gap, reduced pressure zone device or double
check valve assembly as used to contain potential contamination within
a facility. In order for the reduced pressure zone device or the double
check valve assembly to be acceptable, it must be listed on the most
current version of the New York State Department of Health List of
Acceptable Devices (PWS-14).
APPROVED
Accepted by the Village of Williamsville Superintendent as
meeting an applicable specification stated or cited in this section
or as suitable for the proposed use.
AUXILIARY WATER SUPPLY
Any water supply on or available to the premises other than
Village of Williamsville approved public water supply. These auxiliary
waters may include water from another purveyor's public potable water
supply or any natural source(s) such as a well, spring, stream, rainwater,
etc., or used waters or industrial fluids. These waters may be contaminated
or they may be objectionable and constitute an unacceptable water
source over which the water purveyor does not have sanitary control.
CROSS-CONNECTION
Any connection or potential connection which allows or potentially
allows for the intermingling of water from any auxiliary water supply
or any substance from any other unauthorized source with water from
a Village of Williamsville approved public water supply.
CUSTOMER'S WATER SYSTEM
The piping used to convey water supplied by a Village of
Williamsville water supply system throughout a customer's facility.
The system shall include all those parts of the piping beyond the
control point of the Village Water Department. The control point is
either the curb valve or the main valve located in the public right-of-way
that isolates the customer's facilities from the Village or district
distribution system.
HAZARDOUS FACILITY
One in which substances may be present which, if introduced
into the public water system, would or may endanger or have an adverse
effect on the health of other water customers. Typical examples: laboratories,
sewage treatment plants, chemical plants, hospitals, mortuaries and
commercial enterprises. This is a1so defined as any commercial or
business enterprise as defined by zoning or by business use permit.
PUBLIC WATER SUPPLY SYSTEM
The Village of Williamsville water supply system, including
the source, treatment works, transmission mains, distribution system
and storage facilities serving the public. This includes the distribution
system up to its connection with the customer's water system.
REDUCED PRESSURE ZONE (RPZ) DEVICE, ACCEPTABLE
A device containing a minimum of two independently acting
check valves, together with an automatically operated pressure differential
relief valve located between the two check valves. During normal flow
and at the cessation of normal flow, the pressure between these two
checks shall be less than the upsteam (supply) pressure. In case of
leakage of either check valve, the differential relief valve, by discharging
to the atmosphere, shall operate to maintain the 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.
(2) Other terms. All other terms are defined in the Department
of Health and Village of Williamsville Cross Control Manuals and policies
as now in force or as amended from time to time.
D. Requirements.
(1) The customer's water system shall be open for inspection
at all reasonable times to authorized representatives of the Village
of Williamsville.
(2) The Village of Williamsville shall rate a customer's
water system according to its degree of hazard to the public water
system. Some of the factors to be considered are the use and availability
of contaminants, the availability of an auxiliary water supply, and
the type of fire-fighting system in use.
(3) An acceptable backflow prevention device shall be
installed on each service line to a customer's water system at or
near the property line or immediately inside the building being served
but, in all cases, before the first branch line leading off the service
line, as follows:
(a)
Whenever a customer's water system is rated
hazardous, an acceptable reduced pressure zone device or air gap shall
be installed.
(b)
Whenever a customer's water system is rated
aesthetically objectionable, as a minimum, an acceptable double check
valve assembly shall be installed. Unless otherwise determined by
the Water Superintendent, one- and two-family residential water systems
shall be deemed to have nonhazardous classification.
(4) The design of the installation of an acceptable backflow
prevention device must be prepared in accordance with New York State
laws and regulations. The design must be approved by the Superintendent
and/or its agent and all agencies required by the applicable New York
State and Village of Williamsville laws and regulations.
(5) It shall be the duty of the customer at any premises classified as hazardous pursuant to Subsection
D(3)(a) and
(3)(b) above where a reduced pressure zone device, and/or a double check valve assembly, is required to have certified inspections and operational tests done on every containment device, at least once a year. In those instances where the Superintendent deems the hazard to be great enough, he may require certified inspections at more frequent intervals. Certified inspections and operational tests must also be made when any reduced pressure zone device is to be installed, repaired, overhauled or replaced, in addition to the requirement of an annual certified inspection and operational test. All inspections and tests shall be at the expense of the customer and shall be performed by a New York State Department of Health (NYSDOH) certified tester approved by the Village of Williamsville Water Superintendent. The Village Water Department shall make available the names, addresses and telephone numbers of those persons who are certified as testers for such backflow prevention devices. It shall be the responsibility of the water customer per NYS Sanitary Code 5.1.31 a, b, and c to see that such certified inspections and operational tests are made. The customer shall notify the Superintendent in advance, in writing, when the tests are to be undertaken so that he or his representative may witness the tests if the Superintendent so desires. These devices shall be repaired, overhauled or replaced at the expense of the customer whenever said devices are found to be defective. Records of such tests, repairs and overhauls shall be kept and made available to the Water Superintendent. Copies of all testing and maintenance records shall be sent to the Superintendent immediately after the work is performed. Protection of the public water supply and the customer's water system must be in full force at all times. Note: There is no "grace period" for noncompliance or repairs, etc. under any section of this section. Nothing contained in this section grants license for noncompliance.
(6) No water service connection to any customer's water
system shall be installed or maintained by the Village of Williamsville
Water Department unless the water supply is protected as required
by state laws and regulations and this section. Service of water to
any premises shall be discontinued by the Village of Williamsville
Water Department if a backflow prevention device required by this
