(A) This subchapter is supplemental to Section 15A NCAC 18C.0406(b) of the Rules Governing Public Water Systems. Cross-connection control pertains to those residents and business that have their own separate pressurized water system and where the two systems adjoin with any physical connection.
(B) Purpose.
(1) To protect the public potable water supply of the town from the possibility of contamination or pollution, due to backsiphonage or backpressure, by isolation within the consumer's private water system such contaminants or pollutants, which could backflow into the public water system.
(2) To define the authority of the town as the water purveyor entitled to eliminating all cross-connections, new or existing, within its public water system.
(3) To provide a continuing inspection program of cross-connections, which may be installed in the future.
(4) This subchapter will comply with the Federal Safe Drinking Water Act (P.L. 93-523), the North Carolina State Administrative Code (Title 15A, Subchapter 8C), and the North Carolina State Building Code (Volume II) as they pertain to cross-connections with the public water supply.
(C) Responsibility of the town.
(1) The town will be primarily responsible for preventing any contamination or pollution of the public water system. This responsibility begins at the point of origin of the public water supply, includes all of the public water distribution system, including the service connection, and ends at the point of delivery to the consumer's water system. The Public Works Department shall exercise vigilance to ensure that the consumer/customer has taken the proper steps to protect the public potable water system.
(2) When it has been determined that a backflow protection assembly is required for the prevention of contamination of the public water system, the Public Works Department shall notify the owner, in writing, of any such building or premises, to correct within a time set by this subchapter, any plumbing installed or existing that is in violation of this subchapter.
(3) After surveying the private water system the Public Works Department will select an approved backflow prevention assembly required for containment control to be installed at service entrance. See Appendix A attached to Resolution passed September 11, 2012.
(4) Prior to the installation of any backflow prevention assembly, the owner of the private water system must be notified that the installation of a backflow prevention assembly may create a closed system, and as a result thermal expansion may occur. Under such circumstance, the customer must understand and assume all liability and responsibilities for that phenomenon.
