What does the design of a mound system primarily address?

The design of a mound system primarily addresses site and soil conditions because it is specifically engineered to function effectively when conventional septic systems cannot be installed due to poor soil or site constraints. Mound systems create a raised bed of soil that allows for proper drainage and treatment of effluent, particularly in areas where the natural soil is too compact, too shallow, or has high groundwater levels that hinder the infiltration of wastewater.

By elevating the drainage field above the natural grade, mound systems improve aeration and promote the breakdown of contaminants while providing enough absorption area to handle the effluent effectively. The design must take into account various factors like soil texture, permeability, and depth to ensure optimal functioning. A proper assessment and understanding of these site and soil conditions are vital to prevent system failure and to protect the local groundwater and environment.
