Abstract

Two fundamental problems have been associated with the use of large quantities of water – depletion and deterioration in quality. Present advanced wastewater treatment technology has shown that tertiary treatment of wastewater can produce high quality effluents, but large amounts of energy and chemicals must be sacrificed. An alternative to these costly systems is the land treatment system, which utilizes the soil mantle as a multiprocess “living filter” (2). Infiltration-percolation, a land treatment method, can be used for the reclamation of large quantities of wastewater. The infiltration-percolation advance treatment system has been investigated extensively by the Civil Engineering Department at South Dakota State University. South Dakota’s predominantly rural environment makes land treatment a conductive method of advanced wastewater treatment. Initial investigations that considered the soil matrix as a treatment system began with research conducted by Druyvestein (3). Examination of water leaking through the bottom of the Volga, Milbank and Beresford, South Dakota stabilization ponds resulted in the conclusion that good quality water could be obtained by passing stabilization pond effluent through the soil. Further studies using soil lysimeters produced a good quality effluent, but infiltration rates were too low to make the system practical (4, 5).
