[Adopted 12-5-2006 by Ord. No. 12052006]
As used in this article, the following terms
shall have the meanings indicated:
The undesirable flow of water or mixtures of water and other
liquids, solids gases or other substances under positive or reduced
pressure into the Village of Wrightstown Water Utility (hereinafter
"Utility") potable supply of water from any source.
A device or means designed to prevent backflow caused by
backpressure or backsiphonage; most commonly categorized as air gap,
reduced pressure principle backflow assembly, double check valve assembly,
pressure vacuum breaker assembly, backsiphonage backflow vacuum breaker
(spill resistant pressure vacuum breaker) assembly, pipe applied atmospheric
vacuum breaker, flush tank ballcock, laboratory faucet backflow preventer,
backflow preventer for carbonated beverage machine, vacuum breaker
wall hydrants, chemical dispensing machine, hose connection vacuum
breaker, hose connection backflow preventer, backflow preventer with
intermediate atmospheric vent and barometric loop.
An elevation of pressure in the downstream piping system
(pump elevation of piping, or steam and/or air pressure) above the
utility supply pressure, which would cause or tend a reversal of the
normal direction of flow.
The flow of water or other liquids, mixtures or substances
into the distribution pipes of the Utility's potable water supply
system from any source caused by the sudden reduction of pressure
in the Utility's potable water supply system.
Any physical connection or arrangement between two otherwise
separate systems, one of which contains potable water from the Utility,
and the other containing water from a private source, water of unknown
or questionable safety, or steam, gases, or chemicals, whereby there
may be a flow from one system to the other, the direction of flow
depending on the pressure differential between the two systems.
No person shall establish or permit to be established
or maintain or permit to be maintained any cross connection. No interconnection
shall be established whereby potable water from a private, auxiliary
or emergency water supply, other than the public water supply of the
Utility, may enter the supply or distribution system of the Utility,
unless such private, auxiliary, or emergency water supply and the
method of connection and use of such supply shall have been approved
by the Utility and the State of Wisconsin Department of Natural Resources.
It shall be the duty of the Utility to cause
inspection to be made of all properties serviced by the Utility where
cross connection with the public water system is deemed possible.
Residential properties serviced by the Utility shall be inspected
on a ten-year interval. All nonresidential properties serviced by
the Utility shall be inspected on a two-year interval. The Utility
may, but is not required to, perform the cross connection inspection
of the owner's property. If, in the opinion of the Utility, the Utility
is not able to perform the inspection, the property owner must, at
their own expense, have the plumbing inspected for cross connections
by a State of Wisconsin Certified Cross Connection Inspector/Surveyor
or by a State of Wisconsin licensed plumber. The frequency of required
inspections and reinspections, based on potential health hazards involved,
may be shortened by the Utility. The Utility shall charge fees as
approved by the State of Wisconsin Public Service Commission for on-premises
follow-up visits by Utility personnel for reinspection due to customer
noncompliance and for after hours inspections or reinspections.
Upon presentation of credentials, representatives
of the Utility shall have the right to request entry at any reasonable
time to examine any property served by a connection to the public
water system of the Utility for cross connection. If entry is refused,
such representatives shall obtain a special inspection warrant under
Chapter 66.0119 of the Wis. Stats. Upon request, the owner, lesser,
or occupant of any property so served shall furnish to the inspection
agency any pertinent information regarding the piping system on such
property.
The Utility is hereby authorized and directed to discontinue water service to any property wherein any connection in violation of this article exists and to take such other precautionary measures deemed necessary to eliminate any damage of contamination of the public water system. Water service shall be discontinued if the means of backflow prevention required by the Utility is not installed, tested, maintained, and repaired in compliance with this article and Wisconsin Administrative Code NR 811, or if it is found that the means of backflow prevention required by this article has been removed or bypassed. Water service shall be discontinued only after reasonable notice and opportunity for hearing under Chapter 68 of the Wis. Stats., except as provided in § 194-10 below.
Water service to any property discontinued under
the provisions of this article shall not be restored until the cross
connection has been eliminated or a backflow prevention device approved
by the Utility has been installed in compliance with the provisions
of this article. The Utility shall charge fees as approved by the
State of Wisconsin Public Service Commission for the reconnection
of the water service.
If it is determined by the Utility that a cross connection or an emergency endangers public health, safety, or welfare and requires immediate action, service may be immediately discontinued. The owner, lessee, or occupant shall have an opportunity for hearing under Chapter 68 of the Wis. Stats., within 10 days of such emergency discontinuance. Such hearing shall be before the Village of Wrightstown Board of Trustees and shall conform to all existing due process requirements.
The property owner shall be responsible for
the elimination of, or protection from all cross connections on their
premises. The property owner shall, at his or her expense, have installed,
maintained, and tested any and all backflow preventers on his or her
premises in compliance with Wisconsin Administrative Code NR 811and
Department of Commerce Chapter 82. The property owner shall have corrected
any malfunction, revealed by periodic testing, of any backflow preventer
on their premises. The property owner shall inform the Utility of
any proposed or modified cross connections and also any existing cross
connection that are not protected by an approved backflow prevention
device. The property owner shall not install a by-pass around any
backflow preventer unless there is a backflow preventer of the same
type on the by-pass. Property owners who cannot shut down operation
for testing of the backflow prevention device must supply additional
devices necessary to allow testing to take place. In the event the
property owner installs plumbing upstream of the backflow preventer,
such plumbing must have its own backflow preventer. The property owner
is required to follow the protection practices described in the American
Water Works Association publication AWWA M14 titled "Recommended Practice
for Backflow Prevention and Cross Connection Control," unless the
Utility requires or authorizes other means of protecting the public
water system. These requirements or authorizations will be at the
discretion of the Utility.
In the case of premises having internal cross
connections that can not be permanently corrected or controlled, or
intricate plumbing and piping arrangements where entry to all portions
of the premises is not readily accessible for inspection purposes,
making it impracticable or impossible to ascertain whether or not
dangerous cross connections exist, the public water system shall be
protected against backflow from the premises by installing an approved
backflow preventer in the service line. In the case of any premises
where there is any material dangerous to health that is handled in
such a manner that, in the opinion of the Utility, could create an
actual or potential hazard to the public water system, the public
water system shall be protected by an approved air-gap separation
or an approved reduced pressure principle backflow preventer. Examples
of premises where these conditions will exist include sewage treatment
plants, hospitals, plating plants, and car wash establishments. In
the case of any premises where, in the opinion of the Utility, an
undue health threat is posed because of the presence of toxic substances,
the Utility may require an approved air gap at the service connection
to protect the public water system. This requirement will be at the
discretion of the Utility.
