What type of soil is best suited for a mound system installation?

Loamy soil is considered ideal for a mound system installation due to its balanced composition, which includes a mix of sand, silt, and clay. This combination allows for adequate drainage while retaining enough moisture for proper microbial activity, essential for the treatment of wastewater.

The texture and structure of loamy soil facilitate the movement of water through the system, preventing waterlogging and ensuring that effluent can be properly infiltrated into the soil layers. The presence of organic materials in loamy soil also supports a healthy microbial population, which further enhances the breakdown of contaminants in the wastewater.

Mound systems require soils with good percolation rates to ensure that treated wastewater does not pool at the surface, and loamy soils provide that balance of drainage and moisture retention, making them the most suitable option for such installations.
