In areas where site and soil conditions preclude the use of septic tank-soil absorption systems, alternative means of disposal are needed. Further treatment beyond that provided by the septic tank is an alternative that often is suggested. The objective of the improved treatment is either to enhance soil absorption, permitting subsurface disposal in areas where septic tank systems do not function well, or to allow discharge of the effluent directly into surface waters. Intermittent sand filters have been shown to produce a high quality effluent which approaches and can exceed tertiary levels consistently with a minimum of attention.
