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.
They needed not have any heads in the turf because they are a hazard to the horses. So they wanted to water from the edges, the only head that will come close to covering is the Nelson big guns. Originally they were going to be mounted on perminant posts but the fear is that if the wind is blowing a certain way when the show tents are set up we could send 175 gpm into the VIP cocktail tent. So they want to be able to move them. But other than the center head they will stay in place most of the year except when the show is on.

take a look at these end guns Sime vs the nelson. IMO they produce a better water spread and it would be on turf. We use them on our center irrigation systems and they dont produce the deluge of water when the trip arm opperates.
We use them because of the low flow/pressure on the center irrigation pivots.
Looking at the Big Gun specs, I wonder why they didn't amp up the water supply, so they could get a 200-foot throw, and not worry about ever needing a sprinkler inside the arena.
I remember someone telling me a rancher got one of the jumbo heads to cool off a feed lot, but the first mounting was too low to the ground, and supposedly, the high-pressure spray killed one of his steers.

I'm not really buying it, mind you, but maybe there's someone out there dumb enough to not set a big gun above head height. I do remember one residential system done with Thompson rotors with such a high-pressure high-volume spray, that it was painful to touch the stream of water.

The nozzle thrust of the big gun style of head must be pretty high but I have seen these animals up close and personal a time or two and can assure you that they are pretty resilient. The part that amazes me is that someone could actually find a place in a feedlot close enough to the ground to install a big gun that would injure much less kill anything. Posted via Mobile Device
The original system is conventional, but it is a mess. They have multi strad run all over, splices that no one remembers where they are, main line and wire buried under 8' berms. So I thought that 2 wire was they way to go, even though I am only installing 6 zones (sprinklers) given the size of the property expansion is likely.
I was not responsible for any of the trenching on this project. They had their guy do it. I just painted out where I wanted it.
In those pics the spoiles were removed because they used that same trench to fix a drainage problem that they had. They dug the trench 5' down through the clay to sand then back filled 2' with trucked in sand, we installed our main then they filled the rest with sand.
