[Ord. No. 1989.2, 4-10-1989]
A.
The purpose of this Article is:
1.
To protect the public potable water supply from contamination
or pollution by containing within the consumer's internal distribution
system or private water system contaminants or pollutants which could
backflow through the service connection into the public potable water
supply system.
2.
To promote the elimination, containment, isolation, or control
of existing cross-connections, actual or potential, between the public
or consumer's potable water system and non-potable water systems,
plumbing fixtures, and industrial-process systems.
3.
To provide for the maintenance of a continuing program of cross-connection
control which will systematically and effectively prevent the contamination
or pollution of all potable water systems.
[Ord. No. 1989.2, 4-10-1989]
This Article shall apply to all premises served by the public
potable water system of the City of Russellville.
[Ord. No. 1989.2, 4-10-1989]
A.
This Article will be reasonably interpreted by the water purveyor.
It is the water purveyor's intent to recognize the varying degrees
of hazard and to apply the principle that the degree of protection
shall be commensurate with the degree of hazard.
B.
The water purveyor shall be primarily responsible for protection
of the public potable water distribution system from contamination
or pollution due to backflow or contaminants or pollutants through
the water service connection. The cooperation of all consumers is
required to implement and maintain the program to control cross-connections.
The water purveyor and consumer are jointly responsible for preventing
contamination of the water system.
C.
If, in the judgement of the water purveyor or his authorized representative,
cross-connection protection is required through either piping modification
or installation of an approved backflow prevention device, due notice
shall be given to the consumer. The consumer shall immediately comply
by providing the required protection at his own expense; and failure,
refusal, or inability on the part of the consumer to provide such
protection shall constitute grounds for discontinuing water service
to the premises until such protection has been provided.
[Ord. No. 1989.2, 4-10-1989]

control device or air gap separation on an individual fixture, appurtenance,
or system.
The presence of any foreign substance (organic, inorganic,
or biological) in water which tends to degrade its quality so as to
constitute a hazard or impair the usefulness of the water to a degree
which does not create an actual hazard to the public health but which
does adversely and unreasonably affect such waters for domestic use.
Any publicly or privately owned water system supplying water
to the general public which is satisfactory for drinking, culinary,
and domestic purposes and meets the requirements of the Missouri Department
of Natural Resources.
The terminal end of a service line from the public water
system. If a meter is installed at the end of the service, then the
service connection means the downstream end of the meter.

A.
The consumer's premises shall be open at all reasonable times to
the water purveyor, or his authorized representative, for the conduction
of surveys and investigations of water use practices within the consumer's
premises to determine whether there are actual or potential cross-connections
to the consumer's water system through which contaminants or pollutants
could backflow into the public potable water system.
B.
On request by the water purveyor or his or her authorized representative,
the consumer shall furnish information on water use practices within
his premises.
C.
It shall be the responsibility of the water consumer to conduct periodic
surveys of water use practices on his or her premises to determine
whether there are actual or potential cross-connections to his or
her water system through which contaminants or pollutants could backflow
into his or the public potable water system.
[Ord. No. 1989.2, 4-10-1989]
A.
The type of protection required by this Article shall depend on the
degree of hazard which exists, as follows:
1.
An approved air gap separation shall be installed where the
public potable water system may be contaminated with substances that
could cause a severe health hazard.
2.
An approved air gap separation or an approved reduced pressure
principle backflow prevention device shall be installed where the
public potable water system may be contaminated with a substance that
could cause a system or health hazard.

principle backflow prevention device or an approved double check valve
assembly shall be installed where the public potable water system
may be polluted with substances that could cause a pollutional hazard
not dangerous to health.
[Ord. No. 1989.2, 4-10-1989]
A.
An approved backflow prevention device shall be installed on each
service line to a consumer's water system serving premises where,
in the judgement of the water purveyor or the Missouri Department
of Natural Resources, actual or potential hazards to the public potable
water system exist. The type and degree of protection required shall
be commensurate with the degree of hazard.
B.
An approved air gap separation or reduced pressure principle backflow
prevention device shall be installed at the service connection or
within any premises where, in the judgement of the water purveyor
or the Missouri Department of Natural Resources, the nature and extent
of activities on the premises, or the materials used in connection
with the activities, or materials stored on the premises, would present
an immediate and dangerous hazard to health should a cross-connection
occur, even though such cross-connection may not exist at the time
the backflow prevention device is required to be installed. This includes,
but is not limited to, the following situations:
1.
Premises having an auxiliary water supply, unless the quality
of the auxiliary supply is acceptable to the water purveyor and the
Missouri Department of Natural Resources.
2.
Premises having internal cross-connections that are not correctable,
or intricate plumbing arrangements which make it impractical to ascertain
whether or not cross-connections exist.
3.
