Wisconsin Mound Soil Absorption System and Area FillPractice Exam

When sizing criteria is applied to the Wisconsin Mound, what two rates are considered?

1. Basal and Linear Loading Rate

2. Percolation and Flow Rate

3. Surface and Subsurface Flow Rate

4. Influent and Effluent Rate

The correct answer is: Basal and Linear Loading Rate

The correct answer involves the consideration of both Basal and Linear Loading Rates when sizing criteria for the Wisconsin Mound system. The Basal Loading Rate refers to the amount of wastewater applied per unit area over time, which is critical for determining how much water can be effectively treated by the soil in that area without causing saturation or failure. The Linear Loading Rate takes into account the distribution of wastewater across the mound and includes the length and width of the absorption area, helping to ensure that the system can accommodate flow in a manner that supports effective treatment and minimizes the risk of surface breakout. These two rates work together to ensure that the mound is properly sized and designed to handle the expected flows while providing adequate treatment of the effluent. This is essential for maintaining environmental health and compliance with regulations. Other options like Percolation and Flow Rate, Surface and Subsurface Flow Rate, or Influent and Effluent Rate do not specifically pertain to the sizing criteria in the same way that Basal and Linear Loading Rates do, and therefore are not the focus in determining the optimal design for a Wisconsin Mound system.
