Catch Basins Provide Vital Flood Control

Catch basins, also known as storm drains, are an often overlooked part of the City's infrastructure. They are usually located within a curb and are a vital part of flood control, allowing water to quickly drain from the streets. If these basins get clogged by trash or other debris—even snow and ice—flooding may result or other dangerous conditions may occur. Many catch basins in the District are connected to the storm sewers, which may drain directly into area waterways. Others connect to combined sewers and, if clogged, may cause overflow events.

If you see a damaged catch basin, please call DC Water's 24-hour Emergency Line at (202) 612-3400.
