I What is a Septic System And How Does It Work?

Sewage from all Plumbing fixture in the house drains into the Septic Tank, where heavy solids settle to the bottom of the Septic Tank.   Natural Bacterial action produces digested sludge and gases.  The lighter solids, such as grease, oils and fats, rise to form a scum layer.  Solids that are not decomposed remain in the Septic Tank.  From the Septic Tank it is than sent to the Effluent Disposal Area (EDA) or Leachfield through means of gravity or Pumping.
