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.

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.

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 at each end
of the assembly and petcocks and test gauges 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;
Use 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;

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 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.

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

forth in Article 2 of Chapter 6 of Title 32.1, Code of Virginia, as amended.
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.
It shall be the duty of the Mineral Town Council to 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 by Mineral
Town Council in the Cross-Connection Control and Backflow Prevention Program
and as approved by the Virginia Department of Health.
The representative of the Town of Mineral shall have the right to enter
at any reasonable time properties served by a connection to the waterworks
of Mineral 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-connection.
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

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.

of the Town Manager, may not be easily correctable or intricate plumbing arrangements

or restrictions, it is impossible or impractical to make a complete cross-connection
survey.

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 a cross-connection exists
on the premises, 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 the Commonwealth of Virginia Waterworks Regulations and to
the satisfaction of the purveyor.
