Bar Screens

Septic tank


Constructed Wetlands



The treatment process consists of bar screens, followed by two septic tanks and six constructed wetland beds. The bar screens remove larger solids from the waste stream that could clog or damage downstream processes. The waste stream then enters the septic tanks, which allow for the removal of about 30% of the remaining solids as well as much grease and fat. The effluent from the septic tanks is then distributed equally across the six wetland beds via a distribution box. The wetland beds then will remove about 90% of organic waste and pathogens from the waste stream before discharging the cleaner effluent to an irrigation channel.
