Conventional System

A conventional septic system consists of a subsurface gravel bed or series of trenches which receive the septic tank effluent. Effluent can be either pumped or gravity fed from the septic tank(s). The conventional system is installed on sites which have deep permable soils lacking high groundwater, bedrock, or other limiting factors. In Wisconsin, code requires a 36" vertical seperation between the drainfield and these limiting factors. In addition to gravel, a conventional can be installed using plastic leaching chambers.
