Regulation 11 - Direct Potable Reuse

The division would like to thank all stakeholders one last time for their tremendous effort in the Direct Potable Reuse (DPR) project, resulting in successful rulemaking. The thorough, thoughtful input by stakeholders was key in creating this DPR package of regulations and associated policies.

The final regulations are published on the secretary of state's website (version dated 1/14/2023, Section 11.14).  The drinking water policies associated with DPR are policies 16 and 17, also available on our current drinking water policies websiteResponses to comments received about the policies have been posted to the project folder.

The division would once again like to thank stakeholders for their participation. The division will continue working with specific public water systems regarding direct potable reuse. It will also continue to participate and stay connected with organizations like WateReuse Colorado regarding potable reuse in across the state of Colorado.
