Definition: A private waste removal system for homes that are not connected to a community sewer. A conventional septic system consists of three main parts: a septic tank, a drainfield, and the soil beneath the drainfield. Waste is filtered to the soil, where components in the soil neutralize bacteria and chemicals before they reach groundwater or nearby rivers and lakes.
