What is a mound system?

A mound system is indeed an elevated structure designed for effluent treatment. This type of septic system is specifically engineered for areas where traditional septic systems are impractical due to high groundwater tables, poor soil conditions, or limited land space.

In a mound system, the treated effluent is distributed into a sand mound, which is built above the natural soil surface. This mound serves as a biofilter and allows for the natural treatment of wastewater as it percolates through the layers of sand and soil, eventually filtering out contaminants before reaching the groundwater. The elevation of the mound helps ensure proper drainage and prevents flooding or saturation, which could otherwise hinder the treatment process.

Additionally, the design of a mound system is tailored to meet the specific site conditions, taking into account factors such as soil texture and drainage characteristics. This system plays a crucial role in protecting groundwater quality while providing an effective means of wastewater treatment in challenging environments.
