An alternative to the traditional septic system leach field; an engineered leaching field used in areas of Wisconsin where septic systems are prone to failure due to having extremely impermeable soils and/or soils that have a high seasonal water table. If the soil permeability is too low, liquid is not absorbed fast enough, resulting in surface ponding of unsanitary liquids. The mound system provides the correct balance of permeability to assure slow absorption of effluent into the mound before exiting as purified water into the surrounding environment.
