Groundwater recharge systems for stormwater disposal

Abstract

Stormwater has many health and environmental problems, and stormwater management is a major challenge in almost all developing and developed countries. Disposal of Stormwater by Groundwater Recharging is one of the multitudes of structural Best Management Practices (BMPs) developed for mitigating the adverse impacts of stormwater. Very few attempts have been made to treat and use the stormwater in groundwater recharging. Random rainfall events, existence of first flush, and highly variable volumes and pollution loads, make treatment and use of the stormwater in ground water recharging a real challenge. In the present study, the technical aspect of design of groundwater recharge system for stormwater disposal has been taken up. The study involved development of protocol for the design of recharge systems for disposing the pretreated stormwater of two selected sub-watersheds, one urban and the other rural.
