[CC 1999 §28-191; Ord. No. 83-12 §1, 6-27-1983]
A. The
purpose of this Section 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 systems 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.
[CC 1999 §28-192; Ord. No. 83-12 §1, 6-27-1983]
This Chapter shall apply to all premises served by the public
potable water system of the City of Chillicothe.
[CC 1999 §28-193; Ord. No. 83-12 §1, 6-27-1983]
A. This
Chapter will be reasonably interpreted by the municipal utilities.
It is the municipal utilities' intent to recognize the carrying degrees
of hazard and to apply the principle that the degree of protection
shall be commensurate with the degree of hazard.
B. The
municipal utilities 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 consumer is responsible for preventing contamination of the water
system within the consumer's premises.
C. If,
in the judgment of the municipal utilities 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 service to the premises
until such protection has been provided.
[CC 1999 §28-194; Ord. No. 83-12 §2, 6-27-1983]
