(A) Purpose. The purpose of this subchapter is to:
(1) Protect the public potable water supply of the city water system from the possibility of contamination or pollution by isolating real or potential sources of contamination or pollutants which may backflow or cause back siphonage through the service connection into the public potable water supply system, as required by Title 179, NAC 2 “Regulations Governing Public Water Supply Systems”;
(2) 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; and
(3) 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) Applicability. This subchapter shall apply to all premises served by the public potable water system of the city.
(C) Policy.
(1) This subchapter will be reasonably interpreted as the city’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.
(2) The city water division 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 own premises.
(3) If, in the judgment of the Water Division or the state’s Department of Health or their authorized representative, cross connection protection is required through either piping modification or installation of an approved backflow prevention device, 30 days’ notice shall be given to the consumer. The failure, refusal or inability on the part of the consumer to provide requested protection with 30 days shall make the consumer subject to discontinuance of water service at the discretion of the Water Division, according to the degree of hazard, without further notice.
