STORM SEWER Meaning and
Definition
-
A storm sewer, also known as a storm drain, is an underground system of pipes specifically designed to collect and carry away rainwater, meltwater, and runoff from urban areas. It functions as a crucial part of a city's infrastructure, preventing flooding by swiftly channeling excess water from roads, parking lots, and other paved surfaces to a nearby body of water, such as a river or a lake.
Storm sewers are composed of a network of large and small pipes that are strategically laid beneath the streets and sidewalks. These pipes are usually made of sturdy materials like concrete or metal, enabling them to withstand the pressure of flowing water and the weight of vehicles passing above. They are often equipped with catch basins or grates at regular intervals, which act as entry points for the water, preventing debris and litter from entering the system.
The storm sewer system is designed to separate stormwater from sewage to ensure effective and efficient drainage. Unlike sanitary sewers, which transport wastewater to treatment plants, storm sewers are solely dedicated to dealing with clean water. The water collected within the storm sewer pipes is then transported to a discharge point, typically a river, lake, or other bodies of water.
Overall, storm sewers play a vital role in urban drainage by quickly and efficiently moving excess water away from developed areas, reducing the risk of flooding and water-related damage to both public and private properties.
Etymology of STORM SEWER
The word "storm sewer" consists of two parts: "storm" and "sewer".
The term "storm" originally comes from the Old English word "storm", which has Germanic roots. It meant a violent disturbance of the atmosphere, associated with strong winds, rain, thunder, and lightning. Over time, the meaning expanded to refer to any intense or turbulent situation.
The word "sewer" has Middle English origins and was derived from the Old French word "seveour", which means "drain". The Old French word itself was influenced by the Latin word "exaquātor", which means "drainer".
In combination, "storm sewer" refers to a type of sewer system specifically designed to collect and carry away rainwater and other surface runoff during storms or heavy rain events.
