How Sediment Buildup Reduces Storm Drain Capacity
Sediment buildup inside storm drains gradually reduces the system’s ability to move water efficiently.
Fine particles such as sand and soil settle inside pipes and restrict flow over time.
Reduced capacity increases the likelihood of flooding during moderate and heavy rain events.
Sediment removal is often costly and disruptive once it accumulates underground.
Debris caps help prevent sediment from entering drains and preserve system capacity.
