As such, catch basins can become full of leaves, twigs, and dirt. Why Do Catch Basins Need Regular Cleanings?Īs water flows to the streets, it carries a lot of debris. It’s a necessary part of many urban sewer systems because it prevents the blockage of the storm sewer and reduces the flow of pollutants into local waterways. Catch basins also have a trap device that averts the backflow of bad smells coming from the pipes.Ĭatch basins serve as a pretreatment area where sizeable residues settle, particularly in the sump. It’s a point of the drainage system where storm water flows into the sump, and it checks the entry of floating debris to keep anything that shouldn’t be in the sewers from entering the sewers. So what’s involved in catch basin cleaning?Ĭatch basins, also known as storm drains or curb inlets, are holes in the storm drain system with a grate at street level and a sump (a low spot that helps the catch basin manage surface runoff).
