Bangalore is one of the fastest growing cities in India with over 10 million residents. The city has unequal distribution of water supply between and within District Metered Areas (DMAs). Physical and economical aspects of the DMA, like terrain, inadequate infrastructure, high Unaccounted For Water (UFW), socio-economic status, etc. lead to this inequity. In this study, we assess inequity in intermittent water supply between various DMAs of Bangalore South division using Lorenz curve, Gini coefficient, Thiel indices, Atkinson index, generalized entropy index and Hoover Index. Bulk flowmeter and consumer meter data feeding to specific DMAs were collected for a period of 18 months. Inequity indices were calculated for both supply and consumption at each DMA. The results show significant inequity throughout the duration of study indicating inadequate infrastructural capacity and low operational efficiency. It was evident from the study that even with considerable savings in UFW inequity remained more or less the same. A redistribution scheme is also proposed to reduce inequity. This study is a step towards developing an equity-based supply model for Bangalore South division. © 2018 1st International WDSA / CCWI 2018 Joint Conference. All rights reserved.
