Three geothermal wells drilled during the original campus construction vary from 396 m (1,300 ft) to 550 m (1,800 ft). These wells supply all of the heating and part of the cooling needs of the 11-building, 62,200 m2 (670,000 ft2) campus. The combined capacity of the well pumps is 62 L/s (980 gpm) of 89C (192F) geothermal fluids. Swimming pool and domestic hot water heating impose a small but nearly constant year-round flow requirement
