What is a necessary step after installation of mound systems to prevent erosion?

  1. Soil testing

  2. Final cover application

  3. Regular maintenance

  4. Environmental assessment

The correct answer is: Final cover application

The necessary step after the installation of mound systems to prevent erosion is the final cover application. This step is essential because applying a final cover helps protect the soil and the structural integrity of the system from weathering and physical disturbances. The cover layer, typically composed of a mix of topsoil and vegetation, serves multiple purposes: it reduces runoff, promotes water infiltration, and provides stability to the mound. Furthermore, vegetation established on the cover can help bind the soil together with root systems, minimizing the risk of erosion caused by rainfall and wind. In order to maintain the efficacy and longevity of the mound system, it is crucial to implement this step right after installation. By doing so, the system not only functions effectively in treating wastewater but is also safeguarded against environmental factors that could otherwise compromise its operation.
