What is a key maintenance task for a mound system?

Regularly pumping out the septic tank is a crucial maintenance task for a mound system. Over time, solids accumulate in the septic tank, which can lead to clogs and system failures if not removed. By pumping out the tank, you ensure that the system can continue to function effectively. This maintenance helps to prevent the backup of wastewater and protects the soil absorption area from becoming overloaded.

The other tasks mentioned, while they may have some relevance, do not address the primary concerns related to the ongoing operation and maintenance of a mound system. For example, planting bushes might offer some shading benefits but does not fundamentally contribute to the system’s performance or longevity. Building a fence may help protect the area from physical damage or encroachment but does not affect the septic system’s functionality. Reducing the amount of water entering the system, while potentially helpful in some contexts, does not replace the need for regular tank maintenance, which is essential for the proper operation of the entire system.
