Reclaimed Water Work Group

Webpage last updated on 12/6/2017

Purpose

The Reclaimed Water Workgroup provides input regarding the proposed new uses for Regulation 84:

  • Toilet and urinal flushing.
  • Indoor marijuana cultivation.

Update:

Denver Water is no longer pursuing the use of recycled water for livestock wash down and impoundments. Denver Water has also narrowed its proposed use of recycled water for irrigation of edible crops to irrigation of indoor mariguana cultivation.

The informal Regulation 84 stakeholder meetings are complete and there are no more meetings scheduled. The formal Water Quality Control Commission process will begin in spring of 2018. To view a rough timeline for the Commission process, please refer to the Regulation 84 Stakeholder Roles and Responsibilities and Timeline document on this website. Denver Water's draft Reg 84 Regulatory Proposal Meeting Workbook can be downloaded under the Previous Meetings tab under November 2017. If you have any questions, you may contact Damian Higham at Denver Water or Brandi Honeycutt with the Water Quality Control Division. Contact information may be found under the Work Group Officials tab.

Background

Reclaimed Water Control Regulation 84 establishes requirements, prohibitions, standards and concentration limits for the use of reclaimed water that protect public health and the environment while also encouraging its’ use of reclaimed water.

Currently, there are multiple, official uses for reclaimed water including: landscape irrigation, industrial, commercial, fire protection and non-food crop agricultural irrigation. Denver Water, a large water utility authorized to treat reclaimed water, is proposing two new uses: toilet and urinal flushing and indoor marijuana cultivation.

Relevant Documents for Stakeholder Process

Information for Stakeholders

Denver Water is officially proposing to add new uses to the existing regulation. As the proponent (the official term used in the Water Quality Control Commission rulemaking process), they are responsible for several items:

  • Presenting information to the Water Quality Control Division and stakeholders at public meetings.
  • Providing technical evidence to the division to support how the new uses are protective of public health and environment.
  • Soliciting input from stakeholders.

The division is responsible for:

  • Reviewing technical evidence and evaluating whether the proposed new uses are protective of public health and the environment.

During the informal stakeholder process, no final decisions are made and all documentation regarding the proposed regulatory changes remain in draft form.

The formal Water Quality Control Commission process will begin in spring of 2018 (dates are outlined in the overview of potential commission process document). During this time, any person or entity wishing to provide input and participate in the rulemaking hearing must submit what is called a party status request to the commission office. People and entities with party status are then able to respond to the proponent’s pre-hearing statement (the proposal by the proponent (Denver Water), speak in front of the commission during the hearing and also must attend the pre-hearing conference. Public input without party status is also permitted, but depending on the number of parties and amount of evidence to be presented, the time to speak in front of the commission may be limited. The commission is the final decision maker on the proposed new uses.
