NA-06 - Cleaning: Design Measures to Avoid Deposits
Catch basin (2)
Catch basins with a sump retain solids in the sump space located between the bottom of the structure and the lateral invert. The disadvantage of this system is that floatables such as leaves cannot be retained and end up in the sewer system. This is also the case with debris in the sump which gets disturbed during heavy storm events.
