Model Code

The intent of the American Decentralized Wastewater Association (ADWA) Model Performance Code is to provide state and local regulatory agencies with the ADWA preferred quality assurance (QA) and quality control (QC) policy choice options.ADWA represents manufacturers of advanced wastewater treatment components that are listed by American National Standards Institute (ANSI) accredited third party certifiers as complying with NSF/ANSI Standard 40.

ADWA promotes a strong regulatory program in the areas of performance certification for people and treatment components as well as enforced operational maintenance requirements for all onsite wastewater treatment systems. Both program areas are important for the protection of the human and natural environments and the reputation of the decentralized onsite wastewater treatment industry.

ADWA takes the position that engineered treatment components are preferable to siteconstructed treatment components. In this vein, engineered treatment components that are certified by a third-party, ANSI-accredited testing agencies are preferable to noncertified products. Accordingly, this model code emphasizes the use of certified, engineered treatment components that are included in ADWA’s list of approved products.
