SEPTIC TANKS 101

What is a septic tank?

A septic tank system consists of a large, watertight tank that receives waste-water from the home plumbing system.  The tank is followed by an underground consisting of a network of perforated pipe or chambers for distributing partially treated water from water form the septic tank to the soil for final treatment and disposal.

How does a septic tank work?

Septic tanks contain bacteria that grow best in oxygen-poor conditions.  These bacteria carry out a portion or the treatment process by converting most solids into liquids and gases.  Bacteria that require oxygen thrive in the drain field and complete the treatment process begun in the septic tank.  If the septic tank is working well the waste water which flows out of the tank is relatively clear, although it still has an odor and may carry disease organisms.  It should flow only into the drain field.  NEVER ONTO THE GROUND SURFACE OR INTO WATER SOURCES.
