Storm Drainage Systems
The federal government didn’t require solutions for stormwater control before 1990 when it came to development. After 1990, the federal government started requiring controls for stormwater development because of the Clean Water Act of 1987. Storm drainage systems are designed to remove oil, garbage, chemicals, and other types of debris from water collected from storms. A major part of a storm drainage system is a stormwater filter. Stormwater filters are made in several different designs to meet the needs of certain areas. A catch basin insert can strain around 98.31 percent of fat and grease, as well as oil.
Some stormwater management systems utilize a drop inlet spillway, which is a mechanical system used for directing water into a box or a pipe. Storm drainage systems are important for filtering out macroscopic pollutants as well. Macroscopic pollutants are debris that floats on the surface of the water, such as garbage. Nonpoint source pollution is a type of pollution that originates from more than one source. Stormwater runoff may have pollutants collected from many different sources that requires the right storm drainage system and filters to prevent contamination.
