Guiding Documents

The WWUMP is supported by three primary planning documents for the Wastewater Utility:

Service Areas

Boulder's wastewater collection system and the 75th Street WWTP serve residences and businesses within the 26 square-mile Wastewater Utility Service Area (WUSA). Boulder's collection system currently serves a population of approximately 110,000 people and 101,000 employees associated with commercial and industrial businesses.

Projected growth is anticipated to occur primarily through in-fill and redevelopment projects resulting in an estimated 128,000 people and 156,000 employees within the WUSA.

WWUMP Guiding Principles

  1. Protect Public Health and Safety
  2. Protect Boulder's Natural Resources and the Environment
  3. Maximize the use of the Wastewater Utility's Funds
