Regulation 84: Reclaimed Water Reuse
The Water Quality Control Division began a stakeholder engagement process in July 2025 to update Regulation 84: Reclaimed Water Control. Regulation 84 outlines the requirements for the treatment, distribution, and use of reclaimed water in Colorado. The regulation sets water quality standards, practices, and other safety measures to protect the public and the environment while encouraging reclaimed water use.
In 2025, the division hosted monthly meetings to solicit feedback from stakeholders on updates to Regulation 84. The formal rulemaking hearing process under the Water Quality Control Commission’s purview is underway, with the Regulation 84 rulemaking hearing scheduled for April 13, 2026. Please refer to the commission's website and this public folder for all updates on all Regulation 84 rulemaking proceedings going forward.

How to get involved
The division met with stakeholders through virtual meetings to discuss various topics, including:
- Whether Regulation 84 should allow entities to use reclaimed water for snowmaking.
- Evaluating existing and potential new water quality standards and practices to ensure environmental protection and public health.
- Revising existing language for clarity. For example, clarifying actions when the regulation reads, “the division will” or “the division may.”
- Expanding allowable reclaimed water delivery mechanisms (i.e., lay-flat hoses).
- Implementing storage requirements for certain categories of reclaimed water.
- How often treatment facilities report to the division.
The division has concluded hosting stakeholder meetings related to this topic. All meeting materials, including agendas, presentations, and Zoom recordings, are available for review in this public folder.
