b'ECBH DHow It WorksA When designing or building new streets and parking areas, a curb G F inlet is used to assist in the stormwater drainage of the paved surface area. The curb inlet consists of a rst-stage belowground box structure (\x16) with a second stage horizontal throat opening (\x15) that is ush with the paved surface (\x14). As the name implies, the throat opening is placed along the street curb perimeter (D). Internal access to the inlet structure is provided by an iron manhole cover (E). Storm sewer pipe (F) is connected to the inlet structure to provide for drainage out of the structure. Often, the curb inlet structure is used a junction point when an incoming drainage pipe (G) is connected. During a rain event, Model CI Model BBI stormwater (H) drains from the street surface into the throat opening of the curb inlet. This water continues to drain into a sewer pipe that is connected to the curb inlet box structure. The stormwater sewer piping is placed at a downward-sloping gradient to encourage water to ow through the piping; this is also known as gravity-ow. The stormwater eventually ows into a stream, river, ocean, or type of public estuary.Model EI Model BI Visit curbinlets.parkusa.com for more information and design assistance.OptionsTo request a quote or catalog, Curb inlets can also be outtted with optional devices to increasevisit request.parkusa.com.its pollution collection performance of debris, sediment, nutrients, and hydrocarbons.APPLICATIONSGood to useCommercial Residential Municipal Industrial Low Impact in BMPsDevelopment'
