Rooftop Rainwater Harvesting

This report by Central Ground Water Board presents a compilation of case studies on rainwater harvesting and artificial recharge and impact of such measures in ameliorating problems related to groundwater. Groundwater caters to the demand of ever growing domestic, agricultural and industrial sector of the country and is being indiscriminately exploited by several users. On the other hand, rapid urbanization and land use changes has resulted in reduced natural infiltration or recharge of aquifers.

This has led to various problems related to quantity and quality and issues like the decline in water levels, depletion of groundwater resource and quality deterioration. There is thus an imperative need for augmenting the valuable groundwater resource. Artificial recharge and roof top rainwater harvesting is one such method that can revive this precious resource. Several traditional and scientifically proven artificial recharge and rainwater harvesting techniques have been adopted in different parts of the country. These structures have proven to be viable option for augmenting the groundwater aquifers by making use of surplus surface runoff.
