Advanced Onsite Wastewater Treatment Systems Operation and Maintenance Workshop


October 15-16, 2008


Middle Tennessee Research and Education Center

Spring Hill, Tennessee


Tennessee has proposed a rule change that will allow the use of residential-scale advanced wastewater treatment systems.  Please note that this rule change is PROPOSED, and is not yet in effect.  It is anticipated that manufacturers of aerobic treatment units (ATUs) and packed-bed media filters will be looking for Tennessee-based representatives to serve this new market.  If the proposed rule change is implemented, homeowners with advanced onsite wastewater treatment systems will be required to maintain an O&M contract with approved service providers.  This two-day workshop will provide the information needed to inspect, operate and maintain advanced wastewater treatment systems.


Who Should Attend?

  • Those who are interested in becoming residential advanced wastewater treatment system service providers or who are interested in representing a manufacturer of advanced onsite wastewater treatment technologies.
  • Installers who want to learn more about how these advanced systems operate.
  • Soil Scientists and other environmental professionals who work in the onsite wastewater treatment area.
  • Engineers and designers who need a better understanding of how to design these systems for easy maintenance and longevity.
