A latching solenoid (i.e. DC solenoid) doesn't need a holding current. I'm sure someone will correct me if there are DC latching solenoids where this is not the case.

Boss, I think a better question might be why not just use latching solenoids on all valves? What is the advantage for having an AC solenoid in irrigation valves?
