Douglas County Water Resources


Douglas County water users primarily obtain their supply from the non-renewable ground waters of the Denver Basin aquifers. While the aquifers are believed to contain large quantities of water, their levels are depleting at much faster rates than once believed.  It is no secret that additional renewable water supplies are necessary to help augment existing ground water resources, while ambitious water conservation efforts are needed by all County water users.

Efforts are underway by Douglas County Government, water supply providers, and other entities to find solutions to our current water supply limitations.  Some of these efforts include:

  • Enforcement of Douglas County’s Water Supply Overlay District regulations;
  • Work by multiple water provider consortiums to tackle County water supply and conservation issues;
  • Creation of a Douglas County Water Conservation Program that includes a comprehensive indoor and outdoor water audit of all County owned facilities, and provides technical assistance to smaller water providers in the creation of their own water conservation plans.

Douglas County’s population is estimated to grow to over 450,000 people by the year 2030.  Therefore, we must all work together to ensure that both existing and future populations have an adequate water supply, while individually taking conservation steps to reduce our water use.
