Design of Bio-retention Filter Basin for Conservation and Purification of Storm water runoff in Urban Areas

Abstract

Urban areas are more susceptible to water logging and subsequent flood conditions because of reduced rate of infiltration arising from construction activities particularly during the monsoon season. However, if the storm water runoff is conserved and purified, it will be useful to cater to the needs of the huge population in urban areas during the periods of less rainfall or non-monsoon season. Bio-retention basins are best management practices that use a biogeochemical process within a vegetative eco-system to provide soil moisture retention and purification of storm water. While this structure has been implemented in many countries around the world, it is yet to be implemented in Indian cities with necessary modifications considering the topography, population pressure, hydrological characteristics of a basin, and the soil and water management practices. This project work is oriented to design a bio-retention filter basin in the parking lots or roadsides or streetscapes in Indian urban cities.
