"Once the mainline is done, how are the sprinkler heads and laterals to be installed?" has been and will be a frequent question asked. For a good reason too and let me describe this process to you. The mainline is anywhere from 6 -16 inches in diameter. With that size and open trench is necessary for installation. The lateral pipes are only 2 inches in diameter. You will see rolls of them near 6 and 12 green. Another advantage of HDPE is that it can flex and bend around greens, slopes and rock.
Here are a couple of pictures from my trip to Cherry Hills CC last fall. They have a very similar irrigation system to what we will have. The top picture is the plow that pulls pipe and communication wire from the mainline to each sprinkler head. The bottom picture is the end result. As you can see, this pipe is pulled in a circle around the green with a couple of heads installed as well. (Click on the pictures to make them larger) The pipe and wire is 12 inches below the surface so it does not interfere with any future maintenance practices such as aerification. The best part is the minimal clean up; a roller or tamp to put the turf back into place is all that is needed.
"What about the rock?" Well, yes this is the Rocky Mountains. If they get into a situation where pulling is not an option than an open trench will be required. Remember though, it is only a 2 inch pipe so the size of the trench will be significantly smaller than any of the mainline trenches. With any turf damages sod or seed will be used to rejuvenate the area.
Another note, 1.23 inches of rain for the month of June.
