Septic Systems, what are they?

A small sewage treatment system.  Same things as the large treatment plants that sewer systems use to treat wastewater, but smaller to fit onto residential lots and very effective at treating wastewater before discharging into our ground water supply. (Pictured to the far left is a mainline from the house to the tank, in the middle picture is a overview of a simple tank and drainfield, and the picture to the far right is a drainfield bring installed.)
