(A)   No water service connection to any premises shall be installed or maintained by the water division unless the water supply is protected as required by state regulations and the provisions of this article.
   (B)   The purposes of this article are:
      (1)   To protect the public potable water supply from actual or potential cross-connections by isolating within the premises contamination or pollution that could backflow or siphon back into the water supply system because of some undiscovered or unauthorized cross-connection on the premises;
      (2)   To eliminate existing connections between drinking water systems and other sources of water that are not approved as safe and potable for human consumption;
      (3)   To eliminate cross-connections between drinking water systems and other sources of water or process water used for any purpose whatsoever that jeopardize the safety of the potable water supply;
      (4)   To prevent the making of cross-connections in the future;
      (5)   To encourage the exclusive use of public sources of water supply;
      (6)   To protect the potable water supply within the premises where plumbing defects or cross-connection may endanger the potable water supply available on the premises;
      (7)   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.
   (C)   The intent of this article is to recognize that there are varying degrees of hazard and to apply the principle that the degree of protection should be commensurate with the degree of hazard.
