List of Proprietary Products

List of Proprietary Products

The list of proprietary and other reviewed products may include manufactured systems, subsystems or components within the treatment works and disposal works if the products significantly contribute to the treatment performance of the system or provide the means to overcome site limitations. The designer must select treatment systems from this list based on identified site-limiting conditions and applicant requirements.

ADEQ has reviewed the products and services based on third-party performance demonstrations and finds that, if properly installed in suitable locations and properly maintained, these products and services meet ADEQ rules of protecting public health and the environment: 

Note that:

  • Treatment systems that were “Reauthorized November 2005” do not have specific listing certificates; they are listed as meeting the default performance requirements in rule.
  • Treatment systems that have an “Approval Certificate” may contain additional treatment performance standards and additional design or installation constraints. The designer must conform to the requirements in rule and those in the Approval Certificate.
  • Systems not in the listing cannot be considered for installation in the Notice of Intent for an on-site wastewater treatment system.

The application for new installation of proprietary products is limited to those products that have been reviewed and listed by ADEQ.1
