#2. Inspect catch basins and drain pipes for clogs

As part of your drainage system, catch basins capture excess water at low points in your lawn/landscape, under downspouts, near your home's foundation, and more. They should be inspected regularly, especially before and after significant rain events to ensure the system can effectively manage the volume of stormwater.

• Check the inlet grate and clear debris from grate openings.
• Remove grate to inspect inside the drain pipe or catch basin.

• Remove grate to inspect inside the drain pipe or catch basin. 
• Check the catch basin sump area where debris from stormwater flow can settle, and remove collected debris at least twice a year. Clean more frequently if runoff carries a lot of debris.
• If using a catch basin filter, remove it and shake out losse devris. Wash the filter with a hose if it appears clogged with silt and clay.
• Check the drain pipes beneath the grate or outletting from the catch basin. If you have trouble seeing due to the angle of piping, try using your phone camera to take a picture.
• Remove any debris from the piping with a plumbing snake.
