What is required for upslope runoff in relation to mound systems?

For mound systems, it is essential to manage upslope runoff properly to maintain the system's effectiveness and integrity. Diverting upslope runoff around the mound is crucial because uncontrolled water flow over or into the mound can saturate the system, disrupt the treatment process, and lead to potential failure.

If the runoff were to flow into the mound, this could introduce excess water that the system is not designed to handle, potentially leading to overloading and inefficiencies in wastewater treatment. Allowing runoff to flow over the mound might also cause erosion or hydrological imbalances that would compromise the mound’s structure and function. Funnel systems into drainage ways could be useful in certain contexts but would not address the specific requirements for mound systems effectively.

Thus, diverting the runoff around the mound helps to maintain the water balance necessary for proper aeration and function of the septic system while protecting the mound's physical structure and treatment efficiency.
