Storm Drains
Storm drains are pipes that carry away storm water. Rain water goes into these pipes. the water enters the pipes through grates. Grates are metal openings on streets or parking lots. Storm drains are specialized drainage systems which are designed to handle an excess of water as a result of flooding or heavy rainfall. They are frequently found in major cities, especially in flood prone areas. A number of systems are used for the collection and ultimate discharge of water from these drains.
When rainfall is heavy, the streets, parking lots, and other flat areas of a town can flood. In addition to the water falling directly on these surfaces, gutters also discharge large amounts of water into the street. The flooding can pose a hazard, which is why storm strains are installed. The storm drains are frequently located on either side of a street, at a low point in the roadway where water would naturally collect. Typically, a large grate covers the drain, which takes the form of a giant pipe. Cities use these to help move rain water.

How Storm Drains have affected Flooding:
When water from the storm drains flows into a body of water, it can potentially distribute flooding to locations downstream, in the case of a river. It also poses a major pollution risk, because spills in the streets will be carried through the unfiltered storm drain system.
When a storm drain is linked with the sewage system and the water level is controllable, the processing offered by the sewage treatment plant is beneficial. However, if water levels start to rise beyond the capacity of the system, backups can cause the discharge of raw sewage into streets and waterways.
