What is a mound system in septic installation?

A mound system is classified as an alternative septic system specifically designed to address challenges posed by poor soil drainage conditions. In many situations, conventional septic systems rely on the infiltration of effluent into the soil. When the soil has low permeability or is too shallow to accommodate a traditional system, a mound system becomes a viable solution.

This system involves the construction of a raised mound of sand and gravel, which creates a suitable environment for wastewater treatment. The effluent is distributed evenly throughout the mound, allowing for proper aeration and filtration as it percolates through the layers of sand and gravel into the underlying soil. Because of this design, mound systems can effectively treat sewage in environments where standard septic systems would fail, such as in areas with high groundwater tables, clay soils, or shallow bedrock.

Understanding this context highlights the mound system's importance in septic installation, particularly in regions where traditional methods are not feasible due to soil conditions.
