Stormwater Detention Vault
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 or build a surface facility such as a detention basin or retention basin. Detention vaults manage stormwater ''quantity'' flowing to nearby surface waters. They help prevent flooding and can reduce erosion in rivers and streams. They do not provide treatment to improve water quality, though some are attached to a media filter bank to remove pollutants. Design and installation Underground stormwater detention allows for high volume storage of runoff in a small footprint area. The storage vessels can be made from a variety of materials, including corrugated metal pipe, aluminum, steel, plastic, fiberglass, pre-cast or poured-in-place concrete. The vault is typically buried under a parking lot or other open l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parking Lot Stormwater Detention System
Parking is the act of stopping and disengaging a vehicle and leaving it unoccupied. Parking on one or both sides of a road is often permitted, though sometimes with restrictions. Some buildings have parking facilities for use of the buildings' users. Countries and local governments have rules for design and use of parking spaces. Car parking is essential to car-based travel. Cars are typically stationary around 95 per cent of the time. The availability and price of car parking supports and subsidize car dependency. Car parking uses up a lot of urban land, especially in North America - as much as half in many North American city centers. Parking facilities Parking facilities can be divided into public parking and private parking. * Public parking is managed by local government authorities and available for all members of the public to drive to and park in. * Private parking is owned by a private entity. It may be available for use by the public or restricted to custom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
