Hi, We are doing a mobile home park with central irrigation water. 35 units, bid teh ENTIRE park. homes are about 10 feet apart. My thought is to pull a pipe down between each home, then trench the funny pipe over to where the sprays go. We are doing the MP rotators whcih don't use much water. so, what is an efficient way to dig the funny pipe? I'm figuring 350 sprinklers for hte project, so if I can save 5 minutes a sprinkler, that turns into 20 hours, or 500 bucks. thoughts? would an edger work? how do you guys dig funny pipe? thanks again!
