Catch basins are storm sewer inlets that filter out debris such as leaves and litter. They are typically located next to street curbs or within the rear yards of residential areas.
It is important to maintain catch basins to prevent storm sewer blockages and minimize the amount of pollutants entering storm sewers, which discharge into detention basins or directly into streams.
Clogged catch basins can also cause water to pond along streets and in yards and parking lots. This flooding can be a nuisance to motorists and businesses.
Are You Responsible for Catch Basin Care?
Your business is responsible for maintaining any catch basin that is located on your property.
How Are Catch Basins Maintained?
1. Remove Debris from Grates
The grates of catch basins can become clogged with litter or leaves, especially in the spring and fall. Regularly inspect the grate and remove debris.
2. Remove Debris from Storage Area
Catch basins should be cleaned out before the storage area is half full. Once this level is reached, debris begins to wash into sewer pipes. Cleaning should be done in the spring after the first large snow melt, in the fall after trees have shed their leaves, and additionally if needed.
To find out how much material has accumulated in the storage area of your catch basin, insert a long pipe or broom stick into the storm drain grate. Notice where the pipe or stick hits the debris and continue to the bottom to estimate the depth of accumulation.
If the catch basin is shallow enough, you may be able to clean it out yourself with a shovel and bucket. Be careful not to drop the grate down the opening when you remove it; it can be extremely hard to retrieve. If you can't perform your own maintenance, professional services are available to do it for you.
