MMWC's Water Source MMWC obtains its water from wells in Gillette Flats that tap into the Gillette Flats alluvial aquifer. The Gillette Flats aquifer lies in the West Beaver Creek valley, which is filled with alluvial deposits -- including coarse sand, fine gravel, and redeposition of Pikes Peak granite -- derived from stream and glacial erosion. The aquifer is recharged by the West Fork of West Beaver Creek. The aquifer is bounded by the Trachyte Knob to the east, unweathered Pikes Peak granite below, and a narrow valley constriction to the south, near Altman. In 2004, the Colorado Department of Public Health and Environment, Water Quality Control Division, prepared a "Source Water Assessment Report" for Mountain Mutual Water Company.
