(A)   The objective of the backflow prevention chapter for the city is to protect the potable water supply of the city. This will be accomplished by requiring the use of appropriate backflow protection methods. The possibility of contamination will be isolated by confining within the customer’s private water system those contaminants or pollutants which could, under adverse conditions, backflow through uncontrolled cross-connections into the public water system.
   (B)   The following are state regulations incorporated herein by reference:
      (1)   815 KAR 20:120 Kentucky State Plumbing Law, Regulations and Code 1995-1996, Water Supply and Distribution Section 2(4):
         (4)   “Cross-connections shall be prohibited except as approved by the authority having jurisdiction, and suitable protective devices shall be installed.”
         (5)   “Cross-connections between a private water supply and a public water supply shall not be made.”
         (7)   (h)   “Inspection of Devices: Periodic inspections shall be made of all backflow and back-siphonage preventers to determine if they are in proper working condition. Reduced pressure principle back pressure backflow prevention devices shall be tested on at least an annual basis. Records shall be kept on all inspections.
      (2)   401 KAR 8:020, Section 2, Paragraph (2):
         “Cross-connections prohibited. All cross-connections are prohibited. The use of automatic devices, such as reduced pressure zone backflow preventers and vacuum breakers, may be approved by the cabinet in lieu of proper air gap separation. A combination of air gap separation and automatic devices shall be required if determined by the cabinet to be necessary due to the degree of hazard to public health. Every public water system shall determine if or where cross-connections exist and shall immediately eliminate them.”
      (3)   401 KAR 8:101 Section 1(29)
         “Cross-connection” means a physical connection or arrangement between two otherwise separate systems, one of which contains potable water and the other being either water of unknown or questionable safety, or steam, gas or chemicals, whereby there may be flow from one system to the other, the direction of flow depending on the pressure differential between the two systems.
