Mound Septic System

A mound septic system is a type of wastewater treatment system used in areas with high water tables, shallow bedrock, shallow soil depth or other soil limitations. It works by treating and disposing of household wastewater in a way that minimizes the risk of contamination to the surrounding environment.

A mound septic system typically works:

  1. Wastewater from the house flows into a septic tank, where solids settle to the bottom and bacteria break down organic matter.

  2. The liquid portion of the wastewater (effluent) then flows from the septic tank to a series of pipes or chambers in the mound system.

  3. Effluent from the septic tank flows to a pump chamber where it is pumped to the mound in prescribed doses. Treatment of the effluent occurs as it discharges to the trench and filters through the sand, and then disperses into the native soil.

  4. In the mound system, the effluent is distributed evenly over a bed of specially selected soil, sand, and gravel. This bed is built above the natural soil surface to improve treatment and disposal.

  5. As the effluent percolates through the mound, it undergoes further treatment as it encounters the soil and natural microorganisms. This process helps to remove harmful bacteria, viruses, and other contaminants.

  6. Finally the treated effluent either evaporates, transpires through plants, or percolates down into the natural soil, where it is further purified before reaching groundwater.

 

Overall, the mound septic system provides a way to safely and effectively treat and disperse wastewater in areas where traditional septic systems may not be feasible due to soil or site conditions.

 

Mound systems are often used in sensitive environmental areas due to their enhanced treatment capabilities and the protection they offer to groundwater resources. However, they require more space and maintenance compared to conventional septic systems.

 

As with all household sewage systems, the homeowner must maintain the system by preserving the area and prevent the compaction of the soil. This means cordoning the area off and keeping heavy equipment like tractors off the mound during and after the construction of your home (note: a lawnmower is just fine).
