I wish I had more details at this point, I have seen a aerial picture of this site but haven't been there in person. The property is big enough my boss is talking about using Toro golf heads and putting in an agriculture tank to hold enough water to complete one cycle of the entire system. He even mentioned digging in the tank deep enough that it could gravity fill and eliminate the need for a second smaller pump to fill the tank. I am used to working with city water and not pumps. My biggest concern is the quality of water coming off the lake, that is why he wanted to use larger heads that were more suited for dirty water. He mentioned using an escalator pump? to do the high flow work for the sprinklers. Any thoughts, ideas, experience so we cover all the bases? Thanks, Corey.
