Disclaimer for NMED Approval of Liquid Waste Treatment and Disposal System Products

Liquid waste treatment and disposal system products are approved by the New Mexico Environment Department (NMED) for use in permitted on-site liquid waste systems based on information submitted to the Department and recommendations from the Wastewater Technical Advisory Committee (WTAC).  The WTAC has established performance criteria for secondary and tertiary wastewater treatment systems.

Improper installation, operation or maintenance may cause some of these products to fail to function properly, which may include failure to meet treatment performance criteria.  NMED’s approval of any liquid waste treatment or disposal system product as eligible for permitting does not impart or imply any guarantee that the product will, in fact, function properly.  Malfunctioning liquid waste treatment and disposal systems may result in hazards to public safety, health and welfare, degradation of water quality, and in violations of applicable Liquid Waste Disposal and Treatment regulations and standards, 20.7.3, NMAC.

Some product manufacturers have made claims, in company websites, literature and advertisements, with regard to issues other than meeting WTAC performance criteria.  In some instances, NMED has determined that these claims are either incorrect, or have not been demonstrated to be valid using the scientific method of inquiry.  Examples of such claims include, but are not necessarily limited to, assertions regarding treatment process, effluent quality, necessity of tank pumping, drainfield performance or longevity, and regulatory permitting requirements.  NMED’s approval of any liquid waste treatment or disposal system product as eligible for permitting does not impart or imply any endorsement of, or concurrence with, any claims made by the manufacturer.
