Understanding Septic Tank Solutions

One of the most important steps towards enjoying a successful septic tank design project is to avoid the generic one-size-fits-all approach. Every property and situation is unique, which is why the septic tank choice must match your unique needs.


There are many attributes to consider including the size of the septic tank, its location, its integration with other features like drain fields, its costs, and its long-term performance. Perhaps most importantly, it’s vital to understand the different types of septic tank and system set-ups. McNair Septic allows you to tap into any of the main solutions, which are;

  • Gravity - a simple septic tank and drain field system that lets solid waste settle in the tank while liquid effluent flows out from an outlet.
  • Pressure Distribution - the septic tank will also be linked to a pressure pump that equally disperses treated water across the drain field.
  • Aerobic - the tank is connected to an aeration pump that accelerates the treatment process by introducing oxygen to the tank chambers.
  • Sand Filter - a sand filter sits between the drain field and the pump chamber. The tank itself will continue to collect the waste, with treated water moving quite quickly.
  • Subsurface Drip - in this set-up, wastewater enters a dose tank from the house and flows to the aerobic treatment tank. 
  • Glendon Pods - both a septic tank and a pump tank are required, along with the mound pods. Effluent needs to enter the pump tank as soon as the septic tank starts to fill.


Mound and Oscar II systems are also available. Septic tank design choices, specifically relating to the size and type of tank used, will be heavily influenced by the overall system.
