Cross connections are prohibited unless appropriate backflow protection is provided to prevent backflow through the cross connection into the public water system. Appropriate backflow protection for various applications is described in "Recommended Practice for Backflow Prevention and Cross-Connection Control": American Water Works Association (AWWA) Manual M14, Third Edition 2004 and as subsequently amended in Rule 62-555.330 Florida Administrative Code (FAC) and the requirements as follows:
(a)
An approved backflow prevention assembly or means, appropriate to the degree of hazard, shall be installed on each service connection to a customer's water system as close as practical to the city water meter at or near the property line and in all cases before the first branch line leading off the service line, wherever the following conditions exist:
(1)
For premises using an auxiliary water [supply].
(2)
For premises on which any industrial fluids or any other objectionable substances may be stored or handled that may create an actual or potential hazard to the public water supply or utility system.
(3)
For premises having internal cross connections, intricate plumbing or piping arrangements.
(4)
For premises where entry to all portions of the premises is not readily accessible or practical for inspection purposes.
(5)
For premises in which backpressure may be generated in the customer's system.
(6)
All dedicated irrigation services.
(7)
All dedicated fire services.
(8)
