Unless the context specifically indicates otherwise,
the meaning of terms used in this article shall be as follows:
The unobstructed vertical distance through the free atmosphere
between the lowest opening from any pipe or faucet supplying pure
water to a tank, plumbing fixture or other device and the rim of the
receptacle.
Any water system on or available to the premises other than
the waterworks. These auxiliary waters may include water from another
purveyor's waterworks; or water from a source such as wells, lakes
or streams; or process fluids; or used water. They may be polluted
or contaminated or objectionable or constitute a water source or system
over which the water purveyor does not have control.
The flow of contaminants, pollutants, process fluids, used
water, untreated waters, chemicals, gases or 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 to a 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.
This is a term derived from an evaluation of the potential
risk to health and the adverse effect upon the waterworks.
An approved assembly composed of two single, independently
acting check valves, including tightly closing shutoff valves, located
for testing the watertightness of each check valve.
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.
An arrangement or device that will allow alternate but not
simultaneous use of two sources of water.
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.
Any fluid or solution which may be chemically, biologically
or otherwise contaminated or polluted which would constitute a health,
pollutional or system hazard if introduced into the waterworks. This
includes but is not limited to:
Polluted or contaminated waters.
Process waters.
Used waters originating from the waterworks
which may have deteriorated in sanitary quality.
Cooling waters.
Contaminated natural waters taken from wells,
lakes, streams or irrigation systems.
Chemicals in solution or suspension.
Oils, gases, acids, alkalies and other liquid
and gaseous fluids used in industrial or other processes or for firefighting
purposes.

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 requirements
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 the service connection
means the downstream end of the meter.
A condition posing an actual or the 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
and domestic use and the distribution thereof to the public or residential
consumers as set forth in Article 2 of Chapter 6 of Title 32.1 of
the Code of Virginia.
[Amended 6-18-1991 by Ord. No. 1991-1]
The Town Manager shall be responsible for the
administration and enforcement of the provisions of this article.
A.
No person shall install or maintain a water service
connection to any premises where cross connections to the Town's water
system or a consumer's water supply may exist unless such cross connections
are abated or controlled to the satisfaction of the Town.
B.
No person shall install or maintain any connection
whereby water from an auxiliary water system may enter the Town's
or consumer's water system unless the auxiliary water system and the
method of connection and use of such system shall have been approved
by the Town.
A.
The General Superintendent or the duly appointed agent/inspector
shall cause inspections to be made of properties served by the waterworks
where cross-connection with the waterworks is deemed possible. The
frequency of inspections and reinspections, based on potential health
hazards involved, shall be established in the Cross-Connection and
Backflow Prevention Control Program and as approved by the Virginia
Department of Health.
B.
The designated inspector for the Town shall have the
right to enter at any reasonable time properties served by a connection
to the Town waterworks for the purpose of inspecting the piping system
or systems for cross-connections. Upon request, the owner or occupants
of property served shall furnish pertinent information, if available,
pertaining to the piping system or systems on such property. The refusal
of such information or refusal of access when requested shall be deemed
prima facie evidence of the presence of cross connections.
A.
An approved backflow prevention device shall be installed
on each service line to a consumer's water system where, in the judgment
of the Town, a health, pollutional or system hazard to the water system
exists.
B.
An approved backflow prevention device shall be installed on each service line to a consumer's water system serving premises where the following conditions exist, except as noted in Subsection B(7) below:
(1)
Premises having an auxiliary water system, unless
such auxiliary system is accepted as an additional source by the Town.
(2)
Premises on which any substance is handled in such
a manner as to create an actual or potential hazard to the water system,
including premises having sources or systems containing process fluids
or waters originating from a waterworks which are not under the control
of the Town.
(3)
Premises having internal cross connections that, in
the judgment of the General Superintendent, may not be easily correctable

booster pump when the pressure in the waterworks drops to a minimum
of 10 pounds per square inch gauge.
(8)
Other premises specified by the Town when cause can
be shown that a potential cross-connection hazard exists.

[Amended 6-18-1991 by Ord. No. 1991-1]
[Amended 6-18-1991 by Ord. No. 1991-1]
The Town Council may deny or discontinue the
water service to a consumer if the required backflow prevention device
is not installed in a reasonable period of time not to exceed 30 days
from the date of any notice through certified mail. If it is found
that the protective device(s) has been removed or bypassed or if a
cross connection exists on the premises or if the pressure in the
waterworks is lowered below 10 pounds per square inch gauge, the Town
Council 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 the Commonwealth of Virginia Waterworks
Regulations and to the satisfaction of the Town Council.
