Abstract

This paper presents results of a survey that was conducted in one of the suburbs (Hebbal) of Bengaluru, India. The main objective of this paper is to investigate the existence of decentralized water supply system in Bengaluru. Bengaluru gets its water supply from both surface and groundwater sources. The average water consumption in the Hebbal area was found to be about 179 LPCD. Out of this, it was estimated that 145 LPCD is piped water supply (supplied by Bengaluru Water Supply and Sewerage Board (BWSSB)) and the rest 34 LPCD is obtained from other sources. An economic analysis considering capital and operating costs over 20 years period indicated that the net present value (NPV) for the water obtained from the household’s own borewell costs Rs13/ kL which is 50% of the cost of piped water supply. This appears to support use of decentralized water supply for Bengaluru residents.
