A subsurface sewage disposal system, commonly known as a septic system, consists of two main components: the septic tank, also known as the treatment tank; and the drainage area, often referred to as the lateral field. The system also includes a main sewer line (which connects all plumbing fixtures to the septic tank), and a distribution box (which connects the septic tank to the drainage field). The septic tank is buried approximately 10 to 15 feet from the dwelling. The purpose of a septic system is to treat and dispose of wastewater generated by the occupants of the property. When properly installed and adequately maintained, septic systems are more economical than sanitary sewers and just as efficient.
