What feature distinguishes mound systems from traditional septic systems?

Mound systems are characterized by their distinct construction, where the treatment and dispersal components are elevated above the natural ground level. This elevation is crucial for several reasons. Firstly, it allows for effective drainage when the native soil lacks adequate percolation capacity, making it necessary to raise the system so that effluent can be suitably treated before it enters the surrounding environment. The elevated mounds often include layers of soil and gravel that facilitate the filtering and absorption of wastewater.

The design is also influenced by the site's topography, groundwater levels, and the soil's ability to absorb water. By raising the system, it helps prevent issues related to saturation during heavy rains or wet seasons. Hence, the key distinguishing feature of mound systems is their above-ground construction, which addresses specific site limitations that traditional septic systems may not be able to accommodate effectively.
