After what type of event should all inlets and outlets be inspected?

Inspecting all inlets and outlets after major storm events is crucial for several reasons. During such events, significant volumes of water can flow through the stormwater management system, which may cause debris accumulation, erosion, or damage to infrastructure. The high intensity and volume of rainfall can lead to sediment and pollutants being washed into the system, potentially impacting its functionality and water quality.

Post-storm inspections allow for the assessment of the performance of the stormwater system under stress, helping identify any blockages, structural damage, or changes in sedimentation patterns. These inspections are essential for maintaining the effectiveness and longevity of stormwater management practices, ensuring they can handle future events and reducing the risk of flooding or environmental harm.

Routine maintenance and annual reviews are important, but they do not address the immediate impacts of significant weather events. Likewise, inspections related to construction activities focus more on ensuring compliance during the building process rather than assessing the effects of major storms on the established infrastructure. Therefore, inspecting inlets and outlets after major storms is the most critical approach for ongoing resilience in stormwater management.
