A drainage device, typically a basin or pit at the entrance to a sewer, designed to catch debris, sediment, or stormwater runoff before it enters the main drainage system.
In engineering and urban planning, it refers to a structural component designed to collect, temporarily hold, or filter surface water and particulates. More metaphorically, it can describe any system or entity that collects and contains unwanted or overflow elements, such as a department that handles overflow work.
Dialectal Variation

Cleaning frequency depends on location and debris accumulation. Municipalities often clean them 1-2 times per year, but areas with many trees may require more frequent cleaning to prevent blockages.
In its core technical sense, no—it is designed for liquid (water) drainage. However, metaphorically, the term is occasionally used to describe any system that collects and holds overflow or unwanted items.
A catch basin is a defined, often pre-cast, structure with an inlet grate. A French drain is a trench filled with gravel or rock containing a perforated pipe that disperses water. A French drain might discharge into a catch basin, but they are different components.
