The system of pipes that carries rain water from urban streets back to the ocean. Overwatering your yard can also cause water to run into the streets and into storm drains.

Storm drains are separate from sewers, which is a separate system of pipes to carry wastewater from homes and businesses to a treatment plant or reclamation plant for cleaning.
A system of gutters, pipes, or ditches used to carry stormwater from surrounding lands to streams, ponds, or Buzzards Bay.

That portion of a drainage system expressly for collecting and conveying former surface water in an enclosed conduit. Often referred to as a 'storm sewer', storm drains include inlet structures, conduit, junctions, manholes, outfalls and other appurtenances.
A storm drain, storm sewer, stormwater drain (Australia) or surface water system (UK) is designed to drain excess rain and ground water from paved streets, parking lots, sidewalks, and roofs. Storm drains vary in design from small residential dry wells to large municipal systems. They are present on most motorways, freeways and other busy roads, as well as towns in areas which experience heavy rainfall, flooding and coastal towns which experience regular storms.
