[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]

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.
