Abstract

The exponential growth of population, dynamics of industrialization, and expanding real estate business in Bengaluru have put high pressure on water resources and the demand-supply gap is ever widening. The loss of open lands, lakes, and ponds resulted in the depletion of groundwater and the city has no option but to resort to water conservation. Ever since Bangalore Water Supply and Sewerage Board (BWSSB) passed the Rainwater Harvesting Regulation in 2009 a policy-driven initiative has started to popularize Rain Water Harvesting in Bengaluru city. This study examines the technical and non-technical factors affecting the water conservation potential of the Domestic Rain Water Harvesting system (DRWH) in the independent houses in the city of Bengaluru. Using the OLS regression model the main determinants of water conservation potential of the DRWH are identified as catchment area, type of roof, number of water sources, and house area. The study finds that there are 13.76% water savings per household per year with DRWH structures.
