Sustainable urban water supply in south India : Desalination, efficiency improvement, or rainwater harvesting?
The authors propose a framework that makes it possible to evaluate a wider range of centralized and decentralized policies for urban water supply than previously considered. Posted on 11 May, 2011 05:26 PM

Abstract:

A hydrologic-economic modeling approach for analysis of urban water supply dynamics in Chennai, India
In this paper, we discuss a challenging water resources problem in a developing world city, Chennai India. Posted on 11 May, 2011 05:21 PM

 

The goal is to reconstruct past system behavior and diagnose the causes of a major water crisis.  In order to do this, we develop a hydrologic-engineering-economic model to address the complexity of urban water supply arising from consumers’ dependence on multiple interconnected sources of water. 

Factors determining informal tanker water markets in Chennai - Blog post by Veena Srinivasan
Many developing world cities have seen the emergence of informal markets. Posted on 11 May, 2011 05:15 PM

 In these, private tanker truck operators transport water extracted from peri-urban wells to urban consumers.  This study adopted a systems modeling approach to analyzing the informal tanker market in India.  The results indicate that the demand for tanker supply was caused by lack of groundwater availability in private wells as well as unreliable piped supply.

River bank filtration in Uttarakhand - Blog post by Neelima Garg
Bank filtration describes pumping of ground water through drinking water supply wells (tube wells) from aquifers that are in hydraulic connection to adjacent rivers of lakes. Posted on 11 May, 2011 02:30 PM

Process of River Bank Filtration technology

Pumping induces seepage from the surface water into the aquifer and results in quality improvements enroute to the well by natural processes such as filtration, biodegradation, adsorption, redox reactions and mixing. RBF can also occur under natural conditions as a result of an influent river.

Recycling of water during distillation in laboratories and industries saves gallons of water - Blog post by Dr K K Sharma
Glass distillation is commonly used in almost all the laboratories in the world for preparation of distilled water, plant extraction and in many pharmaceutical processes. Posted on 11 May, 2011 02:21 PM

 In the process of distillation vapors passing through the condenser tube are cooled and condensed by water flowing through condenser tube in the condenser unit of the apparatus. In almost all laboratories the water used for cooling the condenser tube is coming from the water supply tap near the wash basin. The precious water after circulating through the condenser tube is left into the drain as wastewater. It has been observed that about 40 liters of water is required for cooling for making 500 ml of distilled water. The water after cooling is generally left to go into the drain.

The following video has been prepared by me and is released by youtube. The video gives good information for those who want to learn about the traditional method of glass distillation and the modified Recycling Distillation Technique (Sharma, 2004) that saves gallons of water.
