When would you use a Mound Septic System?

The mound system was created to combat 3 different types of environmental conditions that make using a traditional septic system problematic.

  1. Permeability of the soil- if it is too slow or too fast than a mound septic system could be a solution as compared to traditional septic systems that are more suitable for more permeable soils
  2. Shallow soil cover – if the layer of soil is too shallow and then becomes creviced or porous bedrock then a traditional septic system may not be feasible
  3. High-water table- If you property has a high water table, meaning it has a high groundwater level, than it may not be able to support a traditional septic system, and you may require a mound septic system

Any of these site conditions or a combination of these conditions can create a need for a non-traditional drain field, aka a mound.
