Water Quality Division: Engineering Review: Product Listing of Proprietary and Other Wastewater Treatment Products

The Engineering Review (ER) Program of the Aquifer Protection Permit (APP) Program is required by the Arizona Administrative Code, (A.A.C, R18-9-A309(E)) to maintain a list of proprietary and other reviewed products that may be used for on-site wastewater (septic) treatment facilities. This list of proprietary and other reviewed products includes systems or components within the treatment and disposal works, if those products significantly contribute to the treatment performance of the system or provides a means to overcome site limitations. By rule, the list does not include septic tanks, effluent filters, or components that do not significantly affect treatment performance or provide the means to overcome site limitations. An application form and adequate supporting performance data is required in order to place a new product on this list.

The listing by ADEQ of any proprietary product or service is not an endorsement by ADEQ or the State of Arizona. ADEQ does not endorse, represent, guarantee, warranty or defend the use of any of the products or services you voluntarily provide information on, use, or receive. These product and service providers are a direct source unrelated to ADEQ or the stateof Arizona. Use of any listed product or service is at your risk and the State assumes no liability.
