Thanks wreelyclean!,
I think ill leave the standpipes idea alone for now, especially the designated hydrants! (sort of defeats the object).
Anyway this might sound a stupid question, but would i have to get a license to use a customers water supply? given that most households use their own hose/sprinkler systems to water their gardens, but as we all know most of us don`t pay the extra on the water rates for the privilege!
Also where could i get a copy of the C.O.S.S.H regs?
