[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.
