Georgia Septic Installer Practice Test

When constructing a Wisconsin mound system, is it permissible to remove tree stumps?

1. Yes, always

2. No, they must remain

3. Only if they are small

4. Only if approved by an inspector

The correct answer is: No, they must remain

Removing tree stumps when constructing a Wisconsin mound system is generally not permissible because the stumps can affect the structural integrity and functionality of the system. The roots of trees and their stumps can create voids in the soil, leading to uneven settling and potentially compromising the percolation of effluent within the mound system. In addition, leaving stumps in place helps maintain soil structure and prevents erosion. The decomposition of the stump over time can also create space for bacteria and other microorganisms that help break down waste in the system. Therefore, regulations are in place to ensure that the natural soil and ecological characteristics are preserved, which is critical for the effective operation of septic systems. This practice supports optimal drainage and minimizes disruptions to the surrounding ecosystem, making it essential to adhere to these guidelines when constructing such systems.
