Rain that touched a parking lot and now needs therapy before it sees a river again.
means Runoff from rain or melting snow that flows over streets, roofs, and pavement instead of soaking into the ground, and has to be drained or treated before it reaches natural waterways.
from A plain compound of 'storm' (from Old English/Germanic roots meaning a violent weather disturbance) plus 'water.' The term itself is a modern civil-engineering coinage, rising with 20th-century urban drainage systems once cities realized that paved surfaces turn rainfall into a management problem rather than letting it quietly sink into soil.
