Septic Mound Systems Otsego MNIf you are like many Otsego MN homeowners who have been told that they need a Mound System, you may have some questions. This innovative Onsite Decentralized Sewage Treatment System has been around since the 1970s. The Mound System Diagram pictured here illustrates the way a typical elevated mound is constructed. A Certified Septic Designer and Installer at CSI Custom Septic, Inc. is a Highly Qualified Septic Professional that can assist with every aspect of the process from initial Site Analysis to final Inspection.

 

Engineered Drain Field Sewage System

The earliest version of a Mound System was originally called a NODAK Disposal System and was invented in the 1940s. It was modified in the 1970s into what is commonly used today in situations where a conventional septic system cannot be used safely due to site or soil conditions.

A Mound System is an Engineered Drainfield Sewage System with an elevated, mounded area. It utilizes a Pressure Dosed Sand Filter to treat liquid discharge from the Septic Tank. As you can see in the Mound System Diagram above, there are several components including sand, soil and tubing.

 

Why Do I Need A Septic Mound System?

MN state and local laws require that raw sewage waste be disposed of properly. Many properties lack sufficient soil or conditions to be able to use a Traditional Gravity Septic System. The 3 Main Reasons as for why you would utilize a mound system for your home or business are as follows:

  1. Soil Depth – Shallow Soil that covers over porous or creviced bedrock.
  2. High Water Table where untreated or partially treated sewage could get into the water.
  3. Slow or Fast Permeability Soil. Basically meaning that wastewater absorbs through the soil either too fast or too slow for adequate filtering.
