(A) A user of public water shall obtain written approval by the water utility or authorized inspection agency of any proposed corrective action or protective device before using it or installing it.
(B) The total time allowed for completion of the necessary corrections shall be contingent upon the degree of hazard involved and include the time required to obtain and install equipment. If the cross-connection has not been removed after a reasonable period of time, the water utility shall physically separate the public water supply from the on-site piping system in such a manner that the two systems cannot again be connected by any unauthorized person.
(C) All testable backflow prevention devices shall be tested initially upon installation to be sure that the device is working properly. Subsequent testing of devices shall be conducted at a time interval specified by the water utility and in accordance with the State Department of Environmental Quality requirements. Only individuals approved by the water utility shall be qualified to perform testing, and individuals shall certify the results of the testing.
