stormwater drain
Runoff collection channel
A stormwater drain is a system that channels rainwater and surface runoff away from roads, parking lots, and other paved areas.
Unlike sewers, stormwater drains typically empty directly into natural waterways without treatment: The oil slick disappeared into a stormwater drain.
