Colorado CPO Certification Overview
The CPO Certification in Colorado is required for all public and semi-public pools and spas under state regulation. Oversight is managed by the Colorado Department of Public Health and Environment (CDPHE), Water Quality Control Division, under 5 CCR 1003-5, Swimming Pools and Mineral Baths, which establishes statewide standards for design, operation, sanitation, and water quality for aquatic facilities.
Whether you operate a facility in Denver, Colorado Springs, Aurora, Fort Collins, or Pueblo, this credential helps ensure pool operators meet Colorado’s health and safety requirements. State rules require each public or semi-public pool to have a qualified operator holding a Certified Pool Operator (CPO) credential or another equivalent certification recognized under 5 CCR 1003-5.
All Colorado jurisdictions follow these statewide regulations and accept nationally recognized credentials that meet the CPO or equivalent requirement, including The Training Center’s CPO Certification Course.
