What is the purpose of the vegetative cover on a mound system?

The purpose of the vegetative cover on a mound system is primarily to remove excess moisture and prevent erosion. The roots of the vegetation help stabilize the soil, which is essential in these systems due to their function of managing and treating wastewater. By allowing plants to thrive, they absorb moisture from the surface, thus enhancing the overall treatment process of the mound system. This not only helps maintain the integrity of the structure itself but also reduces surface water runoff and erosion, which could otherwise lead to system failure or reduced efficacy in treating waste. Therefore, the vegetative cover plays a crucial role in both protecting the mound and optimizing its performance in wastewater treatment.
