Septic System (Environment Dictionary)

Septic System: An on-site system designed to treat and dispose of domestic sewage. A typical septic system consists of a tank that receives waste from a residence or business and a system of trenches or beds in the soil for disposal of the liquid effluent that remains after decomposition of the solids by bacteria in the tank. The sludge remaining in the septic tank must be pumped out periodically.
