Rainwater harvesting - A review on conservation, creation & cost-effectiveness

Abstract

Water being one of the classical elements of Earth, is life’s matter and matrix; mother; and medium whose usage rate is always at a hike. The call for conservation of water has always been paramount and there are sundries for conserving it. To reduce the colloidal and shortage of water hitch, the desideratum to conserve water has risen to the next level with the unbalanced water budget equation. In this aspect of interest, Rainwater Harvesting has a pre-eminent role to play and sites the collection and utilization of rainwater and thereby, reducing runoff. A lot of research works and publications dealing with RWH technologies have been insightful. The present paper intends to unearth the various myths and methodologies that are in collaboration with RWH. In addition to the quotidian methods, new flanged technologies will be at a clear glance and the water budget equation balance centralized with examples and cost factors will be explained in a more pellucid way, focusing on the rarity of RWH incorporating the perquisites. High demand of water being a Gordian-Knot, cost-effectiveness along with conservation will be taken into account, thereby proposing suitable and necessary actions with new creative techniques to contrive upon the water as well as energy conservation to meet the apogee demand of water. The cardinal focus of this review paper anent to legitimize water conservation with new creations and the cost-effectiveness of Rainwater Harvesting prudently.
