RECHARGE CAPACITIES OF BOREWELL’S – A REVIEW

Abstract

Global adoption of managed aquifer recharge (MAR) techniques is driven by groundwater depletion from over-extraction and inadequate replenishment. This review provides an overview of research focusing on groundwater recharge, water quality enhancements, and the socio-economic implications of large-scale water recycling projects in India and abroad. Case study, showing the capacity of STW in replenishing aquifers. The data have shown a tenfold increase in the recharging rates of the groundwater in a 58-73% rise. Groundwater quality has also improved, including decreases in hardness, total dissolved solids, and nitrate. Increased agricultural productivity (11-42%), 33% increase in milk production, and a 341% increase in fish yields are some of the socio-economic benefits derived from the water recycling initiative. These finding indicates that STW recycling at large-scale have the potential to be instrumental in sustainable water management and agricultural development. This manuscript compile results from 30 research studies to review the various methods for recharge, their effectiveness and their issues. The paper also explains the goals of groundwater recharge, such as sustainability of resources, improvement of water quality, and reduction of land subsidence. It is expected that this review will give guidelines to choose suitable recharge techniques depending on hydrogeological conditions, settings and regional requirements.
