In what condition may a larger mound area be justified?

A larger mound area may be justified in the presence of numerous or large stumps or boulders due to the need for proper drainage and absorption of wastewater. In septic system design, the soil's ability to naturally filter effluent is critical for effective operation. Stumps and boulders can disrupt the natural flow of water and create restricted areas where effluent cannot be processed effectively.

By expanding the mound area, more soil is made available for filtration, ensuring that the effluent has adequate space to disperse and allowing the system to function efficiently without experiencing backflow or other plumbing issues. This approach helps prevent contamination of the surrounding environment and maintains the overall health of the septic system.

Other conditions, such as having a flat surface, sunny area, or proximity to a water body, may not directly warrant the justification of a larger mound area. A flat surface may already facilitate proper drainage without requiring additional mound space. A sunny area does not inherently affect the wastewater treatment process, and being near a water body could impose more stringent regulations rather than requiring a larger mound.
