Evaluation of Septic Tank and Subsurface Wetland for

Figure 3-7 Retrieve youth in front of boys’ toilet building. The concrete structure

All toilets flush through 4-inch PVC pipe into one horizontal 880-US gallon plastic tank
that empties into a vertical 400-gallon plastic tank. This follows the same design as the
Pisgah septic tanks. This system was built with one snorkel pump aerator in the 800gallon
tank that was powered by two solar panels. The aerator was disconnected several
weeks prior to the evaluation. The septic tank effluent flows approximately 50 feet
horizontally with slight downward pitch to the inlet distribution manhole for the
wetlands.
