Winter heating can be quite a costly utility, but a Swiss University has found a way around that. It seeks to store water underground during winter in a heated storage field connected to the Science City Campus’s buildings through 800, 200-meter-long plastic pipes called probes, which will be added into the underground network by 2020. The probes will be connected to a water circulation system throughout the campus that collects cool AC-generated water all summer long and pumps it through the probes to the underground storage.

The process will require some electricity as well to power generators within the underground storage. The generators will heat the underground water during winter. Nonetheless, the new system will use electrical power much more efficiently than the current use of it to heat the campus. What obstacles are there to universities in the U.S. implementing underground water storage networks?
