Water quality reclaimed water (reuse) permits


The division designed its reclaimed water program to promote the use of reclaimed water in Colorado. It includes requirements for reclaimed water to meet minimal standards and for treaters and users of reclaimed water to employ best management practices and oversee its use.

Treaters and users with reclaimed water impoundments

The Regulation 84 Rulemaking in 2022 established requirements (Regulation 84, Sections 84.6(F)(10) and 84.10(A)(14)) for impoundments containing reclaimed water to either:

  • Meet the allowable seepage rate in Regulation 61.14(9)(a) and obtain a seepage waiver, or
  • obtain a surface or groundwater discharge permit.  

Treaters must work with their users to submit a Seepage Waiver Application for Reclaimed Water Impoundment for each impoundment that contains reclaimed water. 

Email the application to the division, and be sure to include “Seepage Waiver Application for Reclaimed Water Impoundment” in the subject line.

If you submitted liner specifications to the division with a UPC/UASMP in previous years, send your COEXXXXXX number to Brandi Honeycutt, who will determine whether a seepage waiver application is unnecessary because the impoundment liner has already received approval.

The division encourages treaters and their users to submit this application as soon as possible to ensure ample time for division review, issuance of seepage waivers, and/or further instructions or potential compliance schedule. 

All reclaimed water impoundments must meet these conditions by August 14, 2027.

Guidance for becoming an authorized reclaimed water treatment facility

Step-by-step guidance is available for new and existing facilities applying to treat and distribute reclaimed water (also applies to discharging wastewater treatment facilities switching to reclaimed water treatment and use).

Treater applications | Water quality planning targets (WQPT’s) application and engineering review

Before completing a treater application, you must complete and submit a Reclaimed Water Quality Planning Target Application to the division. Engineering must review and approve the facility design before issuing a treater authorization.

Email the application to the division, and be sure to include “Reclaimed Water Quality Planning Target Application” in the subject line.
