Key Features
This septic system diagram includes:
- Two-chamber tank in cross section
- Inlet from the residence and effluent outlet to the absorption area
- Scum, liquid, and sludge layers in each chamber
- Baffles at the inlet, between chambers, and at the outlet
- Inspection ports and covered access ports over each chamber
- Solids retainer ahead of the outlet
The second chamber holds far less sludge than the first, which shows a customer why pumping on schedule keeps solids away from the absorption area.
What is a Septic System?
A septic system treats household wastewater on site: solids settle in the tank, and liquid effluent flows out to an absorption area in the soil. This ArcSite diagram lets you walk a homeowner through each layer, so they understand what they're paying for at pump-out time.
