Management of Scarce Water Sources using Rooftop Rainwater Harvesting In Churu City, Rajasthan

The aim of this study is to provide a solution for the management of various water source available in city to meet the domestic water demand. Rainwater as an alternate source to meet potable water demand of city. Churu lies in hot and semi-arid region of Rajasthan with temperature variation of -2°C- 50°C with annual rainfall between 400-600mm annually. Water supplied to the city is 69LPCD against demand of 90LPCD with scarcity of potable water 100% due to contamination of water with fluoride, nitrate and salinity. Groundwater table is dropping continuously from 1984 (35m), 2010 (40m), 2010 (45-50m), 2015 (50-54m). As a solution to these problems, this research explores, Rooftop Rainwater Harvesting (RRWH) as source of clean water at household level and community level for potable uses. This paper deals the challenge of providing clean water to people by using rain as clean source of water and management of different water sources to check their exploitation in Churu City.
