(A) Whenever the city deems that a customer's service connection contributes a sufficient hazard to the water system, installation of an approved backflow prevention assembly shall be required on the customer's service line at or near the property line, immediately inside the building being served, or at the point of cross connection, depending on the type of hazard. The type of protective assembly required shall be determined by the city depending on the degree of hazard existing at the point of cross connection.
(B) Any inter-connection to a non-potable pressurized irrigation system or private well shall require the installation of an approved reduced-pressure (RP) backflow assembly. These assemblies shall be protected from freezing and shall be installed above ground or with a live drain to daylight such that they cannot be submerged.
(C) In accordance with state and federal guidelines, pressurized fire sprinkler systems which are charged with potable water may not be required to install backflow prevention assemblies.
(D) The customer shall have the right to appeal in writing to the Utility Board any backflow assembly installation requirement of the Water Department Superintendent. In the absence of the appeal, the Water Department Superintendent's decision shall be final.
