If the weather cooperates we will begin work on this project. It is a large horse jumping arena. We will be looping the arena with 4" fed with 6" from a 40 hp submersible. There will be 6 "hydrants" that will have a 3" solenoid valve controlling it that they will connect the Nelson big gun sprinklers to that will be mounted on carts that they can move around. This is similar to what will be built.
