What should be done to ensure underdrains are functioning properly?

Inspecting underdrains after major storm events is essential for ensuring their proper functioning because these events can significantly affect drainage systems. Heavy rainfall and stormwater runoff can cause blockages or changes in flow patterns within the underdrain system. By inspecting after such events, any immediate issues can be identified and addressed promptly, preventing potential flooding or water-related damage.

Regular inspections are crucial, as they allow for the assessment of performance under real storm conditions, providing insights into the system's resilience and efficiency. Catching problems early can help maintain optimal drainage, prolong the life of the infrastructure, and preserve the surrounding environment from erosion or other stormwater impacts.

Monitoring monthly or assessing annually can miss critical problems that arise specifically in the aftermath of significant weather events, while installing backups, while a useful strategy for enhancing system redundancy, does not directly ensure that the primary underdrains are functioning optimally under current conditions. Thus, timely inspections after storms are paramount in validating and maintaining the operational integrity of underdrains.
