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:
