The ACO KerbDrain Inlet Box provides a neat and durable connection between kerbside drainage and vegetated SuDS features. Designed to help direct surface water from the carriageway into a rain garden or bioretention area, by keeping the drained water at a shallow invert.

Used as part of ACO’s wider SuDS Rain Garden Range, the inlet box helps create a robust interface between hard landscaping and green infrastructure, making it easier to integrate rain gardens into highways, residential streets and public realm schemes.
