Liquid Waste Program

Approved Products

The Liquid Waste Program maintains lists of approved products.

Permits for the installation of septic tanks, advanced treatment systems, and proprietary drainfield products will not be issued unless the tank or product has been reviewed and approved by NMED before installation.  Proprietary drainfield products must be reviewed by the Wastewater Technical Advisory Committee (WTAC).  Septic tank manufacturers seeking approval of septic tanks can download the Application and Checklists for Septic Tank Certification Recertification.   Manufacturers of proprietary advanced treatment units (ATU, ATS) or drainfield products can download the WTAC Product Review Document and Product Submittal Application form on the WTAC webpage.

All questions may be directed to Program Specialist Michael Broussard at (505)-476-9125 or
