Storm drains typically require cleaning every five years , with municipalities often cleaning 20 of their systems annually. However, areas prone to heavy debris accumulation or near sensitive water bodies may need more frequent cleaning.

Most storm drains simply collect rain water and channel it away to prevent flooding, carrying polluted runoff to local water resources. Sanitary sewers carry wastewater or sewage from homes and businesses through an entirely separate piping network below city streets.

Storm drain systems can involve both public infrastructure and private property features . Public systems typically include street drains, curbs, and municipal piping. However, once stormwater enters private property, through catch basins, retention ponds, or culverts, the responsibility may shift.

Some of the heavier sediment and small objects may settle in a catch basin, or sump , which lies immediately below the outlet, where water from the top of the catch basin reservoir overflows into the sewer proper.
