Okay, I made some phone calls....A lottt of money to put the coils in and it would be a lottt of money to take them out. They are in the subgrade. Remove everything, start over, regrade, recompact etc. Quote I got was, "They will never take those out" All plastic tubing, including no metal connectors. So there is nothing for the water to eat or corrode. "No maintenance to very very minor maintenance." "Very Infrequently turn the pumps on to circulate the water just to turnover the fluid and prevent any stagnation buildup." "Only maintenance would be the pumps and thats unlikely." "Built to be maintenance free"
Because they are in the subgrade, you are not going to see them at any time...including new turf installation.
So, if the University doesn't use the system in light of all the injury, safety precautions with knees and concussions on a frozen field, that would be pretty short sighted.
