Section 705.010 General Policy.

[CC 1992 §705.010; Ord. No. 442 §1, 5-10-1988]
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 premises served by the public potable water system of the City of Platte City, Missouri.
C. 
Policy. 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.
The Water Purveyor shall be primarily responsible for protection of the public potable water distribution system from contamination or pollution due to backflow of 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.
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.
