Approved Alternative Treatment Technology Products

Residences with septic systems typically use one of several septic technologies: standard, capping fill, pressure distribution or sand filter systems. However, alternatives to these systems do exist for homeowners that require the use of septic systems. Under Oregon Administrative Rules, Chapter 340 Division 71, these alternatives are classified as Alternative Treatment Technologies.  

Alternative Treatment Technologies are wastewater treatment devices. These treatment devices take wastewater generated from a home or business and improve its quality before sending it to a drainfield for further treatment and dispersal. Typically ATT systems are designed to perform as well as a sand filter or provide additional treatment capabilities. Oregon Department of Environmental Quality rules require that an Operation and Maintenance service contract is established and continued for the life of the system.
