What specific procedures should be followed to winterize a mound system?

The recommended procedure for winterizing a mound system involves ensuring proper insulation and avoiding excessive snow compaction. This is important because the insulation helps to maintain the temperature around the system, preventing the soil and components from freezing, which could disrupt the function of the system. Excessive compaction due to heavy snowfall can hinder airflow and drainage within the mound, potentially leading to system failure.

Maintaining appropriate insulation allows for adequate biological processes to continue, which are crucial for the treatment of wastewater in the mound system. By ensuring that snow is not compacted too heavily on the mound, you help to preserve its structure and functionality throughout the winter months.

Other methods like reducing water flow or covering the mound with plastic wrap may not address the critical needs of insulation and managing snow effectively, and cutting back vegetation can disrupt the natural filtration processes or inhibit growth that would otherwise provide additional insulation.
