In order to protect water quality and public health, the Water Quality Control Division implements and enforces water quality management policies and rules established by the Water Quality Control Commission. The Governor-appointed Commission develops the rules for water quality management in Colorado. It holds hearings in each of the state's major river basins to set water quality use classifications and standards, and develops regulations to ensure protection of those uses and standards. The Commission is also responsible for adopting safe drinking water regulations.
The Water and Wastewater Facility Operators Certification Board (WWFOCB) is responsible for adopting regulations governing the certification of operators for water and wastewater facilities and to ensure that all facilities are under the supervision of a certified operator at all times.
