§ 52.08  CROSS-CONNECTION CONTROL PROGRAM.
   (A)   A CROSS-CONNECTION shall be defined as any physical connection or arrangement between two otherwise separate systems, one of which contains potable water from the town’s water system, and the other from a private source, water of unknown or questionable safety, or steam, gases, or chemicals, whereby there may be a flow from one system to the other, the direction of the flow depending on the pressure differential between the two systems.
   (B)   No person, firm, or corporation shall establish or permit to be established or maintain or permit to be maintained any cross-connection. No interconnection shall be established whereby potable water from a private, auxiliary, or emergency water supply other than the regular public water supply of the town may enter into the supply or distribution system of the town, unless such private, auxiliary, or emergency water supply shall have been approved by the town’s Water Utility and by the State Department of Environmental Management in accordance with 327 I.A.C. 8-10.
   (C)   It shall be the duty of the town’s Water Utility to cause inspections to be made of all properties served by the public water system where cross-connections with the public water system is deemed possible. The frequency of inspections and re-inspections based on potential health hazards involved shall be established by the town’s water utility.
   (D)   Upon presentation of credentials, the representative of the town’s water utility shall have the right to request entry at any reasonable time to examine the property served by a connection to the public water system of the town for cross-connections. On request, the owner, lessee, or occupant of any property so served shall furnish to the inspection agency any pertinent information regarding the piping system, or systems, on such property. The refusal of access or refusal of requested pertinent information shall be deemed prima facie evidence of the presence of cross-connection.
   (E)   The town’s water utility is hereby authorized and directed to discontinue water service to any property wherein any connection in violation of this section exists, and to take such other precautionary measures deemed necessary to eliminate any danger of contamination of the public water system. Water service shall be discontinued only after reasonable notice is served upon the owner, lessee, or occupants of the property or premises where a violation is found or suspected to exist. Water service to such property shall not be restored until the cross-connection(s) has/have been eliminated in accordance with the provisions of this section.
   (F)   If it is deemed by the town’s water utility that a cross-connection or an emergency endangers the public health, safety, or welfare and requires immediate action, and a written finding to that effect is filed with the Clerk-Treasurer and delivered to the consumer’s premises, service may be immediately discontinued. The consumer shall have an opportunity for hearing within ten days of such emergency discontinuance.
   (G)   All consumers using toxic or hazardous liquids, all hospitals, mortuaries, wastewater treatment plants, laboratories, and all other hazardous users shall install and maintain a reduced pressure principal backflow preventer in the main water line serving each building on the premises. The backflow preventer must be installed in an easily accessible location not subject to flooding or freezing.
   (H)   The reduced pressure principle backflow preventers shall not be installed below ground level.
   (I)   This section does not supersede the state’s Plumbing Code, the IDEM Rule 327 I.A.C. 8-10, or any plumbing ordinance of the town, but is supplementary to them.
   (J)   In addition to IDEM Rule 327 I.A.C. 8-10-4 (c), certain customer facilities, as determined by the town’s water utility need a backflow prevention device (see division (L) below for list of potential hazards).
   (K)   If, in the judgment of the Water Operator, an approved backflow prevention device is necessary for the safety of the public water system, the Water Operator will give notice to the water consumer to install such an approved device immediately. The water consumer shall, at his or her own expense, install such an approved device at a location and in a manner approved by the Water Operator and shall have inspections and tests made of such approved devices as required by the Water Operator and in accordance with IDEM Rule 327 I.A.C. 8-10.
   (L)   (1)   Almost all water-using facilities may have actual or potential cross-connection hazards. The following is a partial list of facilities where cross-connections are likely to be found and the recommended device for backflow prevention. The type of device or method of protection required should be commensurate with the degree of hazard.
