The backflows are required by the water dept because EPA requires the water
dept to eliminate cross connections from the water system. A good resource is
the American backflow prevention association website abpa.org. The abpa has a
lot of history on this matter. Or the American water work association. I have
a copy of the EPA reg somewhere in the office.

Does anyone know the history of requiring backflow preventers on
sprinkler systems? I just attended a meeting at the city of Phoenix
regarding their backflow requirement. The discussion turned to where
does/did the backflow requirement come from and is there an EPA, Health
Dept. or Federal mandate to install them? The water departments answer
was "because it's in the plumbing code".
