Background:

University of Western Sydney, Australia has conducted projects related to water consumption, water conservation and projects related to water saving in urban areas.

Dr. Dharma Hagare, Civil and Environmental Engineering, School of Computing and Engineering and Mathematics, University of Western Sydney collaborated with Civil Engineering Department, IISc., for analyzing water consumption pattern in Bangalore.

Considering the expertise available at KSCST, the Secretary had assigned the task of carrying out a short term survey in Hebbal area of Bangalore North. The survey would concentrate on a sizeable number of households serviced by Bangalore Water Supply & Sewerage Board and the main focus was to concentrate on water consumption data and its analysis in Hebbal area.

The analysis of the data collected resulted in a comparative study of water supply and demand patterns between Sydney, Australia and Bangalore and the highlights are:

Sydney has a population of 4.12 million spread over 12,428 km2. On the other hand, Bangalore has a population of 8.47 million spread over 741 km2. In terms of sources of water supply, while Sydney gets most of the water from surface water sources, Bangalore gets its water both from surface and groundwater sources. In addition, in the case of Bangalore, there is a considerable amount of water demand met by rainwater harvesting and private tanker supplies. The average water consumption for Sydney is about 293 L/capita/day. On the other hand the average quantity of town water supply to the Bangalore residents (who do not have access to other supplies) is about 190 L/capita/day. This was further reduced to 110 L/capita/day for the households who have access to additional sources such as bore well, rainwater harvested and / or private tanker waters. It appears that the Bangalore water supply system is relatively more decentralised than the Sydney water supply system.

Project Completion:

Data collected successfully and submitted to University of Western Sydney, Australia. Project completion report along with the fund utilization certificate submitted.
