What does "Mound System" refer to in septic design?

The term "Mound System" in septic design specifically refers to a system intended for high-water table areas that incorporates raised mounds of soil. This design is crucial because, in regions where the water table is elevated, traditional septic systems may not function properly due to inadequate soil drainage. The raised mounds elevate the septic drain field above the high water table, allowing for proper treatment of wastewater as it percolates through the soil. This method ensures that the effluent from the septic tank can adequately be treated before reaching the groundwater, thereby preventing contamination and maintaining compliance with health regulations.

Other options do not accurately describe the unique purpose of a Mound System. The first option relates to low-water table areas, which do not require the elevation provided by a mound. The third option discusses landscaping, which is not relevant to septic design specifics. The fourth option describes a tank for waste storage, which is unrelated to the mound structure and its function in wastewater treatment systems.
