What is a mound system?

A mound system is specifically designed as an alternative septic system that elevates the drain field above the natural ground surface. This design is particularly useful in areas with high water tables, poor soil conditions, or where traditional septic systems cannot be effectively implemented due to environmental constraints.

In a mound system, the septic tank treats wastewater, which is then distributed to a specially constructed mound filled with clean sand or soil. This elevation allows for proper drainage and aeration of effluent, which enhances the treatment process before the water ultimately returns to the environment. The mound system helps to protect groundwater quality by ensuring that untreated or partially treated effluent does not contaminate the groundwater supply. This method is a vital alternative where conventional septic systems might not be feasible, making it a significant option for septic installers to understand.
