Regulation 84


The purpose of Regulation 84 is to establish requirements, prohibitions, standards, and concentration limits for the use of reclaimed water to protect the public health and environment while encouraging the use of reclaimed water.

What is Regulation 84 Water / Reclaimed Water?

Reclaimed water is water produced by removing pollutants from wastewater to the point that it is clean enough to be used for irrigation, cooling, and other nonpotable purposes.


Please remember, all Regulation 84 customers should water at agronomic (soil management) rates and check your system often for leaks or broken heads. Please be sure all repairs to the irrigation system are done in the color purple to indicate reclaimed water is being used per section 84.10(A)(2) of Regulation No. 84.  Remember to turn off your system during high winds and rain events as this not only helps keep you in compliance with the reclaimed water regulation but can also save you on your water bill.

Please be sure to keep up to date training logs for all personnel who work with reclaimed water/on the irrigation system per section 84.6(F)(4) of Regulation No. 84. Even if you use a third-party landscape contractor, the legal contact/user is still required to have up to date training logs available on site. ACWWA’s most up to date Reclaimed Water training presentation can be found here. Please note this training must be completed annually.

If there is any change to your Regulation No. 84 user application (UPC or UAMSP) or Notice of Authorization (such as changes to the legal/site contact, changes to the irrigatable area, etc), please reach out to the Regulation No. 84 Coordinator to update your application/permit.


 Violation procedure for Regulation 84 customers are outlined in your Notice of Authorization issued to you by the State of Colorado's Public Health Department, under Section 3, "Use and/or Category Specific Requirements."
