How many drops make up an ocean? Conserve water, every drop counts. Don’t flush our planet. (A Review paper)

Abstract

   Currently, available sources of water face extreme pressures around the globe because of oblivious human activities as well as changing climate. The rainwater harvesting system (RWHS) carries a huge potential to enhance surface and groundwater resources in regions having a poor water supply. Recently, several countries have started to promote the updated implementation of such practices to tackle the problem of growing water demand. These

     These considerations motivated our enthusiasm for looking at its current circumstances and the possibility of RWHS in the future. In this regard, the study aims to identify the evidence gap among different determinants (climate change, reliability, water quality, and financial viability) intertwined with RWHS. In the paper, studies related to the significance of RWHS amidst scarcity of water around the globe, published in valued journals are reviewed. We found that the RWHS becomes economically viable when certain steps and risk assessment methods are executed in planning and maintaining this system. The study concludes that drinking water sufficiency is possible if a sustainable drinking water supply system is built via RWHS.
