Abstract
An earth basin of a waste water clarification plant is divided by two concentric, cylindrical partitions into a central, circular, settling area to which the waste water is fed from an inlet, a circularly annular activating area surrounding the settling area and connected therewith by an overflow, and a final clarification area surrounding the outer partition and extending therefrom to the oval embankment of the basin which extends in a concentric semi-circle 180.degree. about the common axis of the partitions, but is elongated radially over the remainder of the basin circumference.
