Planning for the Future: Gray Water Supply as a Conservation Measure for a Key Water Provider in Douglas County, Colorado

Diminishing water in the Denver Basin aquifers requires Parker Water and Sanitation District plan for the future to ensure availability of supply. Water conservation is one approach to prolonging the life of the aquifers. Homeowner installed gray water systems will help conserve 25 percent of the water needed and reduce the need to pump ground water for irrigation. Non-potable water through gray water systems will reduce the demand on the supplier. Gray water use will prolong a potable supply to Parker for years ahead. For this plan to be effective, Colorado regulations must change to allow gray water use. This goal will be achieved as the mind-set about water conservation shifts and water suppliers and consumers demand modification to policies.
