Wisconsin Mound Soil Absorption System and Area FillPractice Exam

What should be monitored to ensure no water ponding occurs in mound systems?

1. Soil moisture

2. Crown drainage

3. Fluidity of water

4. Water table height

The correct answer is: Crown drainage

Monitoring crown drainage is critical in mound systems because it directly impacts the functionality and effectiveness of the system. Crown drainage refers to the method by which excess water is directed away from the surface of the mound. Proper crown drainage prevents water from accumulating on the mound's surface, which can lead to ponding. Ponding can adversely affect the absorption capacity of the system, potentially leading to system failure or environmental pollution. Ensuring that the crown drains are adequately designed and functioning properly helps maintain the integrity of the mound system and supports effective wastewater management. While other factors, such as soil moisture and water table height, can influence the overall system performance, crown drainage is specifically focused on the surface water management required to avoid standing water.
