The Design Criteria for Potable Water Systems, also known as Safe Drinking Water Program Implementation Policy #5, is a key policy used as a basis for reviewing and making determinations of design applications for drinking water treatment works in Colorado. The division routinely updates the document to maintain industry standards with input from stakeholders. 

The division started a stakeholder process in September 2021 and concluded it in May 2022. Stakeholders were asked to provide input on the scope of the update and participate in working groups to edit the document. Stakeholder feedback was requested on the proposed changes and final edits were made. The division conducted an informational briefing with the Water Quality Control Commission on May 9, 2022. The new design criteria became effective July 1, 2022.

Engagement overview

The division initiated stakeholder feedback on potential design criteria modifications or updates during September 2021. After collecting stakeholder input, the division hosted stakeholder meetings to discuss the identified items and the formation of workgroups. The workgroups met in the fall of 2021 through winter 2022. In winter 2022, the division held additional stakeholder meetings to discuss the workgroup outcomes and present the draft design criteria. 

The division concluded the stakeholder process in May 2022. The final design criteria will be effective July 1, 2022.
