What is the maximum slope allowed for a Wisconsin mound soil absorption system?

The maximum slope allowed for a Wisconsin mound soil absorption system is 12%. This standard is in place to ensure proper functionality and prevent issues related to water drainage and soil stability. If the slope exceeds 12%, it may lead to ineffective absorption of wastewater, causing potential system overload, erosion, or failure. Maintaining this specific slope allows for optimal water percolation, minimizes the risk of surface runoff, and helps to maintain the integrity of the soil absorption system, ensuring that it functions as intended to protect groundwater quality and public health.
