I didn't land the job but the customer was building a pond with a golf green on an island in the pond(yes three hole golf course on the property) and he had the geothermal contractor dig the pond and run a 1 ton loop in it so the excavation of the pond and associated materials were part of it.
That was where it became a stretch for me as the pond was not needed for the heat transfer, but I didn't get the job so I guess I don't have to feel bad about putting in a pond for golfing as part of a tax credit
