ABSTRACT:
A wastewater treatment system of the overland flow type for use with land having impervious or relatively impervious soil comprises a circular land area formed in a succession of concentric annular terraces. The terraces are planted with a grass crop compatible with heavy irrigation, and each terrace slopes radially toward an adjacent annular drain concentric therewith. A rotary distribution system pivoted at the center of the terraces is rotated at a predetermined speed to distribute the wastewater over the terraces.
