Illinois Communities Ramp Up Storm Drain Maintenan

As Illinois heads into another rain season, many cities and counties are increasing storm drain maintenance to keep waterways clear and reduce the chances of street-level flooding during heavy storms. Public works departments say the work typically begins weeks ahead of peak rainfall and focuses on removing debris that can block inlets and slow runoff.

Officials noted that storm drains can accumulate leaves, sediment, litter, and other material throughout the year—especially after windy falls and winter freeze-thaw cycles. When clogged, drains may overflow, sending water onto roads, sidewalks, and nearby properties.
