[R.O. 1991 § 720.010; Ord. No. 1718-97 § 1, 2-18-1997[1]]
A.
The purpose of this Chapter 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.

Editor's Note: This ordinance also repealed former Ch. 720,
adopted 9-8-1987 by Ord. No. 1072 §§ 1-5, as amended.
[R.O. 1991 § 720.020; Ord. No. 1718-97 § 1, 2-18-1997]
This Chapter shall apply to all premises
served by the public potable water system of the City of Smithville,
Missouri.
[R.O. 1991 § 720.030; Ord. No. 1718-97 § 1, 2-18-1997]
A.
This Chapter 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 judgment of the water purveyor
or his/her 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/her 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.
[R.O. 1991 § 720.040; Ord. No. 1718-97 § 1, 2-18-1997]
Unless the context specifically indicates
otherwise, the meaning of terms used in this Chapter shall be as follows:
The unobstructed vertical distance through the free atmosphere
between the lowest opening from any pipe or faucet supplying water
to a tank, plumbing fixture, or other device and the overflow level
rim of the receptacle, and shall be at least double the diameter of
the supply pipe measured vertically above the flood level rim of the
vessel, but in no case less than one (1) inch.
Any water source or system, other than the public water supply,
that may be available in the building or premises.
The flow other than the intended direction of flow of any
foreign liquids, gases, or substances into the distribution system
of a public water supply.

fluids, or other wastes to a degree which could create an actual hazard
to the public health through poisoning or through spread of disease
by exposure.
Any physical link between a potable water supply and any
other substance, fluid, or source, which makes possible contamination
of the potable water supply due to the reversal of flow of the water
in the piping or distribution system.
An evaluation of the potential risk to public health and
the adverse effect of the hazard upon the potable water system.
Any condition, device, or practice in the water supply system
and its operation which could create or may create a danger to the
health and well-being of the water consumer.

water system that has not been properly protected by a vacuum breaker,
air gap separation or backflow prevention assembly.
An actual or potential threat to the physical properties
of the water system or to the potability of the public or the consumer's
potable water system but which would constitute a nuisance or be aesthetically
objectionable or could cause damage to the system or its appurtenances,
but would not be dangerous to health.
An actual or potential threat of severe damage to the physical
properties of the public potable water system or the consumer's potable
water system or of a pollution or contamination which would have a
protracted effect on the quality of the potable water in the system.

a backflow prevention device 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.

of a public water system.
[R.O. 1991 § 720.050; Ord. No. 1718-97 § 1, 2-18-1997]
A.
No water service connection shall be installed
or maintained to any premises where actual or potential cross connection
to the public potable or consumer's water system may exist unless
such actual or potential cross connections are abated or controlled
to the satisfaction of the water purveyor and as required by the laws
and regulations of the Missouri Department of Natural Resources.
B.
No connection shall be installed or maintained
whereby an auxiliary water supply may enter a public potable or consumer's
water system unless such auxiliary water supply and the method of
connection and use of such supply shall have been approved by the
water purveyor and the Missouri Department of Natural Resources.
C.
No water service connection shall be installed
or maintained to any premises in which the plumbing system, facilities,
and fixtures have not been constructed and installed using acceptable
plumbing practices considered by the water purveyor as necessary for
the protection of health and safety.
[R.O. 1991 § 720.060; Ord. No. 1718-97 § 1, 2-18-1997]
A.
The consumer's premises shall be open at
all reasonable times to the water purveyor, or his/her 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/her
authorized representative, the consumer shall furnish information
on water use practices within his/her premises.
C.
It shall be the responsibility of the water
consumer to conduct periodic surveys of water use practices on his/her
premises to determine whether there are actual or potential cross
connections to his/her water system through which contaminants or
pollutants could backflow into his/her or the public potable water
system.
[R.O. 1991 § 720.070; Ord. No. 1718-97 § 1, 2-18-1997]
A.
The type of protection required by this
Chapter 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 any substance that could cause a severe health hazard.
2.
An approved air gap separation or
an approved reduced pressure principle backflow prevention assembly
shall be installed where the public potable water system may be contaminated
with a substance that could cause a system or health hazard.
3.
An approved air gap separation or
an approved reduced pressure principle backflow prevention assembly
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.
[R.O. 1991 § 720.080; Ord. No. 1718-97 § 1, 2-18-1997]
A.
An approved backflow prevention assembly
shall be installed on each service line to a consumer's water system
serving premises where, in the judgment 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 assembly shall be installed
at the service connection or within any premises where, in the judgment
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.
Premises where entry is restricted
so that inspection for cross connections cannot be made with sufficient
frequency or at sufficiently short notice to assure the cross connections
do not exist.
4.
Premises having a repeated history
of cross connections being established or reestablished.
5.
Premises which, due to the nature
of the enterprise therein, are subject to recurring modification or
expansion.
6.

handled under pressure so as to permit entry into the public water
supply, or where a cross connection could reasonably be expected to
occur. This shall include the handling of process water and cooling
waters.
7.
Premises where materials of a toxic
or hazardous nature are handled such that if backsiphonage or backpressure
should occur, a serious health hazard may result.
C.
The types of facilities listed below fall
into one (1) or more of the categories of premises where an approved
air gap separation or reduced pressure principle backflow prevention
assembly is required by the water purveyor and the Missouri Department
of Natural Resources to protect the public water supply and must be
