Definition

A tank, usually underground, into which sewage flows, the deposited matter being wholly, or partially broken down through anaerobic action. The final effluent may be allowed to soak into the ground through a system of agricultural drains, if the soil is suitable. Alternatively, the tank must be emptied at regular intervals by a special road-tanker.
