Performance Evaluations of Groundwater Recharge Rectangular Filtration System for Sand-Mixed Storm-Runoff

Abstract: Need of artificial recharging of groundwater is gaining importance due to sharp decline of groundwater table at many places. For artificial recharging it is desirable that the injected water to the groundwater system is devoid of the sediments and other foreign materials which may hamper the quality of groundwater. This necessitates the storm water runoff to pass through the filtration system before injection. However, there is often problem of clogging of filter, which requires frequent maintenance. Thus, there is a need of proper understanding of working of the filtration system. The present study focuses on performance evaluations of the various filtration systems of varying influent sediment concentrations of the storm runoff in the laboratory.
