[Ord. No. 97-13, Sec. 1]
In compliance with Arkansas Rules and Regulations Pertaining to Public Water Systems, Section VII.E, the Lincoln City Council finds it necessary for the health, safety and welfare of the people served by the water department of the City's utility department to adopt cross-connection control standards which establish the requirements for the design, construction and maintenance of connections to the public water supply. These standards are supplemental, but do not supersede or modify the State Plumbing Code and its latest revisions under which the City operates. This ordinance pertains to commercial and industrial establishments only. Single-family, residential swelling units, unless involved in commercial operations, are exempt from the requirements of this ordinance except where they fall under the purview of the Arkansas State Plumbing Code.
A. 
The purpose of this ordinance is:
1. 
To provide for the protection of the public potable water supply:
2. 
To isolate at the service connection any actual or potential pollution or contamination within the consumers' premises; and
3. 
To provide a continuous, systematic and affective program of cross-connection control.
[Ord. No. 97-13, Sec. 2]
BACKFLOW
A hydraulic condition, caused by a difference in pressures, in which non-potable water or other fluids flow into a potable water system.
BACKFLOW PREVENTER
A device or means to prevent backflow.
DOUBLE-CHECK VALVE ASSEMBLY
A complete assembly meeting applicable AWWA Standards and the requirements of the Arkansas State Plumbing Code consisting of two internally loaded, independently operating check valves between two tightly closing resilient-seated shutoff valves, with four properly placed resilient seated test cocks.
REDUCED-PRESSURE-PRINCIPAL BACKFLOW PREVENTION ASSEMBLY
A complete assembly meeting applicable AWWA Standards and the requirements of the Arkansas State Plumbing Code consisting of a hydraulically operating, mechanically independent differential relief valve located between two independently operating, internally loaded check valves that are located between two tightly closing resilient seated shutoff valves with four properly placed resilient-seated test cocks.
[Ord. No. 97-13, Sec. 3]
A. 
The City water department's Cross-Connection Control Program Handbook of Policies and Procedures is hereby incorporated into this ordinance by reference. It is the primary responsibility of the water purveyor and/or the City of Lincoln to evaluate the hazards inherent in supplying a consumer's water system, i.e., determine whether solid, liquid or gaseous pollutants or contaminants are, or may be, handled on the consumer's premises in such a manner as to possibly permit contamination of the public water system. When a hazard or potential hazard to the public water system is found on the consumer's premises, the consumer shall be required to install an approved backflow prevention device at each public water service connection to the premises in accordance with this ordinance's requirements. The type of device shall depend on the degree of hazard involved. The degree of hazard shall be as described in AWWA Manual M-14 or as described below. Where more than one type of protection is possible, the actual method utilized shall be at the discretion of the water purveyor and/or the City of Lincoln after physical inspection of the hazard.
B. 
In the case of any premises where there is an auxiliary water supply, the public water system shall be protected against the possibility of backflow by a reduced-pressure principle backflow prevention assembly (RP) at the service connection.
C. 
In the case of any premises there is an auxiliary water supply, the public water system shall be protected from the possibility of backflow by a reduced-pressure principle backflow prevention assembly (RP) at the service connection.
D. 
In the case of any premises where there is any material dangerous to health which is handled in such a fashion as to create an actual or potential hazard to the public water system, the public water system shall be protected by an approved reduced-pressure-principle backflow prevention assembly.
1. 
In case of any premises where there are "uncontrolled" cross-connections, either actual or potential, the public water system shall be protected by an approved reduced-pressure-principal backflow prevention assembly at the service connection.
2. 
In the case of any premises where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete cross-connection survey, the public water system shall be protected by the installation of an approved reduced-pressure-principle backflow prevention assembly at the service connection.
[Ord. No. 97-13, Sec. 4]
