[CC 1985 §22-201; Ord. No. 3273 §1, 1-23-2003]
A.
Purposes.
1.
To protect the Ste. Genevieve 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-processes 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 Article is all inclusive and applies to
all premises served by the City's water system and supersedes all
previous ordinances dealing with backflow or cross-connections.
C.
Policies.
1.
This Article will be reasonably interpreted by the City water system
manager or the City Building Inspector. It is the City'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.
2.
The City shall be primarily responsible for protection of the potable
water system from contamination or pollution due to backflow or contaminants
or pollutants through the water service connection. The cooperation
of all customers is required to implement and maintain the program
to control cross-connections. The water system personnel and the customer
are jointly responsible for preventing contamination of the City's
water system.
3.
If, in the judgment of the City, cross-connection protection is required
through either piping modification or installation of an approved
backflow prevention device, due notice shall be given to the customer.
The customer shall immediately comply by providing the required protection
at his/her own expense; and failure, refusal or inability on the part
of the customer to provide such protection shall constitute grounds
for discontinuing water service to the premises until such protection
has been provided.
[CC 1985 §22-202; Ord. No. 3273 §2, 1-23-2003]
A.
No
water service connection shall be installed or maintained to any premises
where actual or potential cross-connections to the City or the customers
water system may exist, unless such actual or potential cross-connections
are abated or controlled to the satisfaction of the City 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 the City's or the customer's water system unless
such auxiliary water supply and the method of connection and use of
such supply has been approved by the City and the Missouri Department
of Natural Resources.
C.
No
new water service connection shall be installed to any premises in
which the plumbing system, facilities and fixtures have not been constructed
and installed using plumbing practices not in compliance with this
document.
[CC 1985 §22-203; Ord. No. 3273 §3, 1-23-2003]
A.
The
customer's premises shall be open at reasonable times upon request
of the City's authorized representative for the conduction of surveys
and investigations of water use practices within the customer's premises
to determine whether there are actual or potential cross-connections
to the customer's water system through which contaminants or pollutants
could backflow into the City's potable water system.
B.
The
customer, upon request, shall furnish the City with information on
water use practices within his/her premises.
C.
It
shall be the responsibility of the water customer to conduct periodic
surveys of water use practices on his/her premises to determine whether
there are actual or potential cross-connections to the customer's
water system though which contaminants or pollutants could backflow
into the customer's or the City's potable water system.
[CC 1985 §22-204; Ord. No. 3273 §4, 1-23-2003]
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 City's
water system may be contaminated with substances that could cause
a severe health hazard. Air-gap shall be as indicated in BOCA National
Plumbing Code Table P-1507.12.1 (Minimum Air-Gaps for Plumbing Fixtures).
An approved air-gap shall be minimum two (2) times the pipe diameter
and under no circumstances shall the air-gap be less than one (1)
inch.
2.
An approved air-gap or reduced pressure principle backflow prevention
assembly shall be installed where the City's water system may be contaminated
with a substance that could cause a health hazard.
3.
An approved air-gap, reduced pressure principle backflow prevention
assembly or approved double-check valve assembly shall be installed
where the City's water system may be polluted with a substance that
could cause a pollution hazard which would not be dangerous to health.
[CC 1985 §22-205; Ord. No. 3273 §5, 1-23-2003]
A.
An
approved backflow prevention assembly shall be installed on each service
line to a customer's water system serving premises where, in the judgment
of the City water system manager, the City Building Inspector 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 approved reduced pressure principle
backflow prevention assembly shall be installed at the service connection
or within the premises where, in the judgment of the City's representative
or the Missouri Department of Natural Resources, the nature and extent
of activities on the premises or the materials used in the 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.
C.
All
lawn irrigation systems connected to the City's potable water system
shall be required to protect the City's system against backflow by
installation of an approved double-check valve assembly or a reduced
pressure principle backflow prevention assembly. Sprinkler systems
designed to allow chemicals to be introduced into the system shall
protect the City's water system against backflow by a reduced pressure
principal backflow prevention assembly.
[CC 1985 §22-206; Ord. No. 3273 §6, 1-23-2003]
A list of approved backflow prevention assemblies will be on
file at City Hall and will be available to customers upon request.
[CC 1985 §22-207; Ord. No. 3273 §7, 1-23-2003]

prevention assemblies required by this Section shall be installed
at a location and in a manner approved by the City and shall be installed
at the expense of the water customer.
B.
Backflow
prevention assemblies shall be located to be readily accessible for
maintenance and testing and protected from freezing. No reduced pressure
principle backflow prevention assembly shall be located where it will
be submerged or subject to flooding by any fluid.
C.
"Containment"
backflow assemblies shall be installed in the customer's service line
in the most practical location between the customer's meter and prior
to any other connection.
D.
"Isolation"
backflow assemblies may be allowed on a single branch line within
the customer's premises if it is determined that line, and only that
line, is a potential threat to the water system. This determination
may be made by a representative of the City Water Department or a
representative of the State of Missouri Department of Natural Resources.
[CC 1985 §22-208; Ord. No. 3273 §8, 1-23-2003]
