I haven't checked the supply specs but ideally it needs a backup power supply (batteries) and a reserve water supply (cistern) in case of utility loss.

I had a simple design I dreamed up using a single rooftop mounted Hunter G90 golf course rotor rated at 60 GPM, having a spray radius of 88ft but needs 90psi. a 3hp pump and 3,600 gallons for every head and hour of use! |
Looks like about $10 a sq/ft. Seems reasonable in a high risk area.
