Topic of delivery : “Sustainable Water Supply Strategy for Bangalore - A model for emerging cities in India.”


Water supply for the city of Bangalore in India is always short against the total demand. Surface water is inadequate to meet the demand and the city has to depend on groundwater. Due to rapid urbanization, infiltration of rainwater into the subsoil has decreased drastically and recharging of groundwater has diminished. This scenario requires an alternative source to bridge the gap between demand and supply. Rainwater, which is easily available and is the purest form of water, would be an immediate source to augment the existing water supply by “catching water wherever it falls”. Recycling or reuse of treated water is another source for at least secondary purposes. Karnataka State Council for Science and Technology (KSCST) is actively participating in the socially relevant, environment friendly water conservation measures and has been providing cost effective solutions since its inception 1975. Rainwater Harvesting (RWH) Cell at KSCST is established to study the needs of the people and provide sustainable and simple solutions through innovation and implementation pertinent to Rainwater Harvesting and Ground water recharge. RWH cell established at KSCST is providing policy support to the Government departments for water conservation and rainwater harvesting programmes in Karnataka and other states in India. RWH App is developed with the support of UNESCO by KSCST for web and Mobile users. Blog "RainManSpeaks from Bengaluru" is in the web since April 1st 2014 and has published 81 posts. Quiz and Debate programs are organised to build awareness on rainwater harvesting and water conservation measures among students and faculty of schools and colleges.

Case Study 1
'Sourabha' Ecofriendly home of Bangalore in India is on a plot area of 2400 Sq.ft. This house is entirely dependent on harvested rainwater for all its need including drinking since 1994.

Case Study 2
The strategy for sustainable water supply plan for a city like Bangalore should have the combination of conventional river water supply augmented by the 'New Water' supply sources - a. Rainwater harvesting, b. Ground water recharge with sustainable withdrawal and c. Reuse of waste water through treatment.
