(A) No water service connection to any commercial, industrial, and certain other facilities shall be allowed by the Superintendent unless the water supply is protected as required by the city Utility Board and this cross connection control policy. Service of water to any premise shall be discontinued by the Superintendent if a backflow prevention assembly required by this policy is not installed, tested, and maintained, or if it is found that a backflow prevention assembly has been removed or bypassed, or if an unprotected cross connection exists on the premises. Service will not be restored until such conditions or defects are corrected.
(B) The Board recognizes the threat to the public water system arising from cross connections. All threats will be classified by degree of hazard and will require the installation of approved reduced pressure principle backflow prevention devices (RP) or double check valve assembly (DC).
(C) An approved RP shall be installed on each commercial, industrial, and certain other facilities' service lines at or near the property line or immediately inside the building before the first branch leads off the service line wherever the following conditions exist:
(1) Any facility that is being constructed or remodeled or is undergoing a change in ownership or occupancy.
(2) Any existing facility required to have backflow protection per 327 I.A.C. 8-10-4.
(3) Any existing facility where multiple, potential or actual, protected or unprotected cross connections exist.
(4) Any existing facility where a customer's water distribution system contains intricate plumbing and piping arrangements or is not readily accessible and available for inspection purposes.
(5) Any existing facility using a booster pump. In addition, the booster pump shall be operated in accordance with 327 I.A.C. 8-10-3.
(6) Any existing facility with temporary connections for filling tanks, tanker trucks, spraying trucks, and other containers.
(D) A customer may request to be exempt from the installation of an RP device on the service line. The customer shall submit an application to the Board requesting approval for the installation of an alternate device or a waiver from installing a device. If an exemption is granted and a change in use occurs at the facility, the exemption shall no longer be valid and the customer shall install an RP device or reapply for an exemption. The following will generally be exempt from the installation of an RP on the service line:
(1) Fire protection systems that do not contain hazardous chemicals may be protected by a properly installed double check detector check assembly.
(2) Land irrigation systems that are not under back-pressure may be protected by a properly installed pressure vacuum breaker.
(3) Any backflow prevention device existing prior to implementation of this policy and properly maintained shall be allowed by the Superintendent to continue in service unless the degree of hazard is such as to supersede the effectiveness of the present backflow preventer or result in an unreasonable risk to the public health.
