The Town of Hillsville hereby adopts by reference
Article 4, Cross-Connection Control and Backflow Prevention Control
in Waterworks, Commonwealth of Virginia Waterworks Regulations in
conjunction with The Town of Hillsville Cross Connection Control Program
Guidelines.
[Amended 11-11-1996]
As used in this article, the following terms
shall have the meanings indicated:
The flow of contaminants, pollutants, process fluids, used
water, untreated waters, chemicals, gases and nonpotable waters into
any part of a waterworks.
Any approved device, method or type of construction intended
to prevent backflow into a waterworks.
The owner or person in control of any premises supplied by
or in any manner connected with waterworks.
Any water system located on the consumer's premises, supplied
by or in any manner connected to a waterworks.
Any introduction into pure water of microorganisms, wastes,
wastewater, undesirable chemicals or gases.
Any connection or structural arrangement, direct or indirect,
to the waterworks whereby backflow can occur.
Any condition, device or practice in a waterworks or its
operation that creates or may create a danger to the health and well-being
of the water consumer.
The presence of any foreign substance (chemical, physical,
radiological or biological) in water that tends to degrade its quality
so as to constitute an unnecessary risk or impair the usefulness of
the water.
A condition through which an aesthetically objectionable
or degrading material may enter the waterworks or a consumer's water
system.
Water fit for human consumption and use which is sanitary
and normally free of minerals, organic substances and toxic agents
in excess of reasonable amounts for domestic usage in the area served
and normally adequate in supply for the minimum health requirement
of the persons served.
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 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 between
the check valves 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.
These devices must be of the approved type.
The terminal end of a service line from the waterworks. If
a meter is installed at the end of the service, then "service connection"
means the downstream end of the meter.
A condition posing an actual, or threat of, damage to the
physical properties of the waterworks or a consumer's water system.
Any water supplied by a water purveyor from waterworks to
a consumer's water system after it has passed through the service
connection.
An individual, group of individuals, partnership, firm, association,
institution, corporation, municipal corporation, county or authority
which supplies water to any person within this state from or by means
of any waterworks.
All structures and appliances used in connection with the
collection, storage, purification and treatment of water for drinking
or domestic use and the distribution thereof to the public or residential
consumers.
[Amended 2-27-2017]
It shall be the duty of the Town of Hillsville
to cause inspections to be made of properties served by the waterworks
where cross-connection with the waterworks is deemed possible. Such
inspections shall be performed annually. The owner of a backflow prevention
device shall hire a certified backflow prevention tester to do this
inspection and report the results to the Town of Hillsville. A certified
report by the tester will be accepted. The frequency of inspections
and reinspections, based on potential health hazards involved, shall
be established by the Town of Hillsville in the Cross-Connection Control
and Backflow Prevention Program and as approved by the Virginia Department
of Health. Frequency of inspections shall not be less than annually.
The representative of the Town of Hillsville
shall have the right to enter at any reasonable time properties served
by a connection to the waterworks of the Town of Hillsville for the
purpose of inspecting the piping system or systems for cross-connections.
Upon request, the owner or occupants of property served shall furnish
to the inspection agency pertinent information regarding the piping
system or systems on such property. The refusal of such information
or refusal of access, when requested, shall be deemed evidence of
the presence of cross-connections.
[Amended 2-27-2017]
The water purveyor may deny or discontinue the
water service to a consumer if the required backflow prevention device
is not installed. If it is found that the device(s) has been removed
or bypassed or if the cross-connection exists on the premises, if
the device has not been and passed an annual inspection, or if the
pressure in the waterworks is lowered below 10 psi gauge, the purveyor
shall take positive action to ensure that the waterworks is adequately
protected at all times. Water service to such premises shall not be
restored until the deficiencies have been corrected or eliminated
in accordance with Commonwealth of Virginia Waterworks Regulations
and to the satisfaction of the purveyor.
[Amended 11-11-1996]
The potable water made available on the properties
served by the waterworks shall be protected from possible contamination
or pollution by enforcement of this article and applicable plumbing
regulations as provided in the statewide plumbing regulations. Any
water outlet which could be used for potable or domestic purposes
and is not supplied by the potable system must be labeled as "Water
Unsafe for Drinking" in a conspicuous manner.
[Amended 11-11-1996]
This article is a supplement to the applicable
plumbing regulations as provided in the Statewide Uniform Building
Code.[2]
