A concrete septic tank is delivered to the site and carefully lowered into the prepared pit. The tank is a two-compartment design, where solids settle in the first chamber, and liquid flows into the second before discharging into the field lines. The 3-inch pipe stubbed out from the house's plumbing is connected to the inlet of the septic tank, including a cleanout access point for future maintenance. The outlet pipe from the septic tank is then connected to the field lines. The presenter notes that they use 'Easy Flow Pipe,' a gravelless pipe system filled with styrofoam peanuts and covered in a mesh, which the subcontractor prefers over traditional chamber pipe for its ease of installation and performance.
