Criteria defining performance of natural wastewater treatment and sludge management systems are presented. Objectives of natural treatment systems are to help treat municipal wastewater and sludge in a cost-effective and energy-efficient manner and recycle and reuse them as resources. Land application of wastewater and sludge is examined. Problems with natural treatment systems are reviewed. Two widely accepted systems included slow-rate land treatment and rapid infiltration of wastewater through basins. Case histories are presented.
