The phase two construction consisted of an Olympic size swimming pool and an indoor field house with athletic offices attached. Phase one, Darby Gymnasium (home of the record-breaking Grinnell men's basketball team), was completed in 2005. A unique aspect of the phase two project included a rain water collection system from the large field house roof and surroundings, which feeds a 20,000-gallon collection tank. Condensate water is also harvested from the air handling system in the field house, which provides a large amount of clean water for the collection tank.
