What are the two basic systems that utilize fill materials in Wisconsin?

The Wisconsin Mound Soil Absorption System is one of the two basic systems that utilize fill materials because it is specifically designed for areas where the soil conditions do not readily support traditional methods of wastewater treatment. This system involves the construction of a raised mound of soil that provides adequate drainage and filtration for septic effluent, ensuring proper treatment and reducing the risk of groundwater contamination.

By using fill materials, the mound essentially creates a suitable environment for microbial activity, which is essential for the breakdown of contaminants in the wastewater. This method is particularly beneficial in locations with high water tables or clayey soils that have low permeability, making it a reliable solution for effective effluent management in Wisconsin.

The Area Fill System, on the other hand, is associated with a different approach for managing wastewater, which may not be considered a fundamental system in the same context as the mound system. The distinction lies in how each system is dependent on the characteristics of the soil and the fill material used, which is why the mound system is notable in the context of this question.
