A graywater (sink and shower wastewater) reuse system is now being designed to serve a visitors' center and a nearby laboratory atop Pikes Peak, Colorado. If the Pikes Peak system succeeds, it will provide an important prototype for water reuse in other arid or remote regions, as well as in manned space exploration. The system will use an immobilized cell bioreactor, reverse osmosis membranes, and other disinfection units to treat graywater, producing water for reuse on-site in nonpotable applications. The entire system will be housed in a recently built army lab, which is currently in use for only four to six weeks out of the year.
