Introduction

Artificial recharge of groundwater and rainwater harvesting are two diametrically opposite methods of effective utilisation of rainwater. Groundwater recharging aims at suppressing surface runoff and evapotranspiration to maximise infiltration for making as much rainwater as possible to become groundwater. Rainwater harvesting on the other hand aims at suppressing infiltration and evapotranspiration to maximise surface runoff for storing as much rainwater as possible in natural or artificial containers for some direct use. The overlap between the two terms arises from the practice of using the water that overflows from the container used in rainwater harvesting for recharging groundwater.
