A.
The consumer's premises shall be open at
all reasonable times to the Director of Public Works or an authorized
representative for the performance 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 water system.
B.
On request by the Director of Public Works
or an authorized representative, the consumer shall furnish information
on water use practices within the consumer's premises.
C.
It shall be the responsibility of the water
consumer to conduct periodic surveys of water use practice on the

cross-connections to the consumer's water system through which contaminants
or pollutants could backflow into the consumer's water system or the
public water system.

§ 51.18; CC 1981 § 29-16; Ord. No. 89-7, 1-17-1989]
A.
The type of protection required by this
Article, shall depend upon the degree of hazard which exists, as follows:
1.
An approved air-gap separation shall
be installed where the public water system may be contaminated with
substances that could cause a severe health hazard.
2.
An approved air-gap separation or
any approved reduced pressure principle backflow prevention device
shall be installed where the public 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 device
or an approved double-check valve assembly shall be installed where
the public water system may be polluted with substances that could
cause a pollutional hazard not dangerous to health.

§ 51.19; CC 1981 § 29-17; Ord. No. 89-7, 1-17-1989]
A.
An approved backflow prevention device
shall be installed on each service line to a consumer's water system
servicing premises where, in the judgment of the Director of Public
Works or the Missouri Department of Natural Resources, actual or potential
hazards to the public 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 judgment
of the Director of Public Works 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 Director of Public Works 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 re-established.
5.
Premises which, due to the nature
of the enterprise therein, are subject to recurring modification or
expansion.
6.
Premises on which any substance is
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 waters and cooling
waters.
7.
Premises where materials of a toxic
or hazardous nature are handled such that if back siphonage or back
pressure should occur, a serious health hazard may result.
C.
The following types of facilities fall
into one (1) or more of the categories of premises where an approved
air-gap separation or reduced pressure principle backflow prevention
device is required by the Director of Public Works and the Missouri
Department of Natural Resources to protect the public water supply
and must be installed at these facilities unless all hazardous or
potentially hazardous conditions have been eliminated or corrected
by other methods to the satisfaction of the Director of Public Works
and the Missouri Department of Natural Resources. The facilities listed
below are not intended to be a complete list of all facilities affected
by this Section. Additional types of facilities may be added per the
judgment of the Director of Public Works.
