Storm drain grate on a street in Warsaw, Poland Storm drain with its pipe visible beneath it due to construction work. A storm drain, storm sewer (United Kingdom, U.S. and Canada), surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved streets, car parks ...
Stormwater, also written storm water, is water that originates from precipitation ( storm ), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff.
A stormwater detention system during installation beneath a parking lot. A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff ...
Stormwater harvesting or stormwater reuse is the collection, accumulation, treatment or purification, and storage of stormwater for its eventual reuse. While rainwater harvesting collects precipitation primarily from rooftops, stormwater harvesting deals with collection of runoff from creeks, gullies, ephemeral streams and underground conveyance.
Dry well. A dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater, in some cases greywater or water used in a groundwater heat pump. It is a gravity-fed, vertical underground system that can capture surface water from impervious surfaces, then store and gradually infiltrate ...
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, [ 1] made up of a succession of elevated features, such as ridges and hills.
Flood control (or flood mitigation, protection or alleviation) methods are used to reduce or prevent the detrimental effects of flood waters. [1] [2] Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood control methods can be either of the structural type ...
Sustainable drainage systems (also known as SuDS, [1] SUDS, [2] [3] or sustainable urban drainage systems [4]) are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure strategy. [5] SuDS efforts make urban drainage systems more compatible ...
