What is Storm Drain Cleaning?

Storm drain cleaning uses vacuum trucks to remove silt, debris, leaves, and accumulated sediment from storm sewer lines, drop inlets, and culverts. Regular maintenance keeps storm systems flowing at design capacity — critical for flood prevention, MS4 compliance, and protecting downstream water quality.
