[R.O. 1996 § 710.010; CC 1968 § 22-7(a
— c); Ord. No. 1835 § 1, 5-15-1989]
A.
Purpose. 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.
B.
Application. This Chapter shall apply to
all service connections to the public potable water system of the
City of Blue Springs.
C.
Policy. It is the intent of the Water Department
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. If, in the judgment of the Water Department 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 their own expense. No water service connection
shall be installed or maintained unless the water supply is protected
as required by this Section. Water service shall be disconnected by
the Water Department if a backflow prevention assembly required by
this Section is not installed, tested, and maintained, or if it is
found that a backflow prevention assembly has been removed, bypassed,
or if an unprotected cross connection exists. Service will not be
restored until such conditions or defects are corrected.
[R.O. 1996 § 710.020; CC 1968 § 22-7(d); Ord. No. 1835 § 1, 5-15-1989]

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 Department the
consumer shall furnish information on water use practices within their
premises.
C.
It shall be the responsibility of the water
consumer to conduct periodic surveys of water use practices on their

the Water Department if such connections are found to exist, and to
make any repairs necessary to bring their water system into compliance
with the provisions of this Chapter.
[R.O. 1996 § 710.050; CC 1968 § 22-7(g); Ord. No. 1835 § 1, 5-15-1989]
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 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.
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 potable water system may be polluted with substances that
could cause a pollutional hazard, not dangerous to health.
[R.O. 1996 § 710.060; CC 1968 § 22-7
(h); Ord. No. 1835 § 1, 5-15-1989]
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 Water Department 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, as determined by the Water
Department.
B.
An approved air-gap separation or reduced
pressure principle backflow prevention device shall be installed on
each service connection where, in the judgment of the Water Department
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.
Service connections having an auxiliary
water supply, unless the quality of the auxiliary supply is acceptable
to the Water Department and is approved by the Missouri Department
of Natural Resources.
2.
Service connections having internal
cross-connections that are not correctable, or intricate plumbing
arrangements which make it impractical to ascertain whether or not
cross-connections exist.

restricted so that inspection for cross-connections cannot be made
with sufficient frequency or at sufficiently short notice to assure
that cross-connections do not exist.
4.

history of cross-connections being established or re-established.
5.
Service connections, which due to
the nature of the enterprise therein, are subject to recurring modification
or expansion.
6.

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.
Service connections 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.
Facilities representing class I backflow
hazards fall into one (1) or more of the categories of service connections
where an approved air-gap separation or reduced pressure principle
backflow prevention device is required by the Water Department and
the 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 Water Department and the
Missouri Department of Natural Resources. Such facilities shall include,

the consumer has corrected or eliminated such conditions or defects
in conformance with this Section to the satisfaction of the Water
Department.
C.
Reasonable notice shall be provided in
writing by the Water Department by personal contact, certified mail,
posting said notice on the consumer's property, or by any other reasonable

the provisions of this Section will be commensurate with the degree
of hazard imposed on the public water supply and shall be at the sole
discretion of the Water Department.
