Greywater Regulation 86 in Colorado

Great News Colorado! As of December 30, 2015 the new Greywater Regulations come into effect! So, what does this mean for us? This means that we can begin to design & install systems, which comply with the (Regulation 86) guidelines laid out for Colorado. Before installing your system, check in with your local building department to make sure that they are adopting these minimum standards. Some counties may require permits or inspections, while others may allow simple systems. Since each bio-region is unique, local governments have the choice to adopt these guidelines or further restrict them. This means that WE NEED YOU! Water Warriors who want to see a new standard for water use in Colorado. Design your system, call your local building department, and start to re-use this precious renewable resource!

Here at Colorado Greywater LLC, we have been working hard for the past 3 years to ensure that these regulations were inclusive of simple and affordable greywater systems as well as large scale institutional systems. Contact us today at to schedule a consultation, register for a 2016 workshop in your area, or to buy your greywater parts!!




Greywater Public Hearing (Regulation 86)

Hello Concerned Citizens of Colorado!
Some of you may have heard that our state will be adopting a new Water law about Greywater Re-use. It has been in the works for almost 2 years and we are on the verge of a final public hearing. If you believe in water re-use and conservation, Please write to the CDPHE ( with the message below and come out to support efficient and practical greywater solutions on April 13th from 9:30-5 at:
Florence Sabin Conference Room
Department of Public Health and Environment
4300 Cherry Creek Drive South
Denver CO 80246.
Wear something green to support the inclusion of “Fruit and Nut trees and other plants where the edible or medicinal part does not touch the soil or water directly” as this is one of our big hurtles in the allowance of truly ecological greywater systems. The beaurocratic process can be slow and frustrating. Please come prepared to wait for your moment to share your thoughts. This public hearing will be addressing the adoption of two new regulations (Reg 61 & Reg 86) and Regulation 86, the greywater rules will be second in the process and therefore it will be discussed later in the day. As a stakeholder in the process, I will have several minutes to state my case in favor of less stringent regulation and the allowance of fruit and nut trees. The case would be made stronger with public support at key moments. In the CDPHE notice to stakeholders, public participation is encouraged “The commission encourages all interested persons to provide their opinions or recommendations regarding the matters to be addressed in this rulemaking hearing, either orally at the hearing or in writing prior to or at the hearing. Although oral testimony from those with party status and other interested persons will be received at the hearing, the time available for such oral testimony may be limited. The commission requests that all interested persons submit to the commission any available information that may be relevant in considering the noticed proposals.”

Feel free to read the current Draft of Regulation 86. (Note: Many people spell it GrEywater to support Ecological Solutions, but the CDPHE spells it GrAywater) If you have time to read the draft, please submit your concerns to ( If you would like to support our effort for less stringent regulation and the adoption of ecological solutions, please send this message to (

Re: Graywater Regulation 86 Public Comments
I support the efficient and practical graywater solutions laid out in Regulation 86. I want to encourage my local county and city to adopt this law with minimal restrictions, and I believe that “mulch basins” provide the most ecologically robust solution for dealing with graywater irrigation. They are practical, affordable, and can utilize gravity to convey the greywater to the landscape without the oversight of complex engineering, pumps, or filters. I plan to use my laundry machine to irrigate my landscape and would like to see a simple permit for those types of simple systems. I also believe that the best beneficial use of graywater is for watering fruit and nut trees, and other plants where the edible part does not touch the soil or water directly. I have never heard of anyone getting sick from an apple on a tree where graywater was used for irrigation, and scientific research supports this approach. For toilet flushing systems, I would like to see less restrictive rules for decontamination, since this water will be used for flushing waste. I support the adoption of Regulation 86 and would like to see these rules become less strict, so that we the people can utilize ecological solutions for our land and the environment. Thank you for your time.
