This paper describes the findings of a study conducted in Nelvoy village in Vellore district, Tamil Nadu, India. Posted on 06 Jun, 2011 05:01 PM

 The study attempted to understand the phenomenon of water contamination in the village by using GIS as a tool to locate and map water supply and sewage distribution systems in the village, in relation to human and animal dwellings, their wastes, sanitary practices and their connections with drinking water quality for a clearer understanding of the connections between these factors and possible

Water – also the factor, which brings the biggest of problems to urban life –

  • mosquitoes,
  • bad stench from clogged dirty canals,
  • floods and water logging especially in the monsoons,
  • roads breaking up because of poor drainage,

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.

 

 

Application of Composite Correction Program for improvement in efficiency of water treatment plants - A WHO paper
Safe drinking water, sanitation, water purification, secured supply, are all unchecked on goals' checklist; emphasizing on the need of intricate tools and plans and their implementation. Posted on 20 Apr, 2011 12:41 AM

The goal of safe and affordable drinking water and sanitation has not yet been achieved. The current practices of water purification are inadequate to produce secured water supply. Maintaining health protection at water supply systems has become more challenging with resistance of some pathogens to disinfection using chlorination and an increase in the immuno-compromised population (e.g., people with HIV, organ transplant patients, the elderly).

In this context, it has become essential to develop various tools such as Composite Correction Programme (CCP) and Water Safety Plans (WSP) to improve water purification and distribution systems, to achieve the goal of providing safe drinking water.

Wastewater reuse in apartment buildings in Bangalore - S Vishwanath
As apartments spring up in all parts of the city , it is imperative that certain steps be put in place for the safe and sustainable management of water and sanitation. Posted on 14 Apr, 2011 10:12 AM

 Even if an apartment uses as less as 5000 litres of water a day it must have a wastewater recycling system which does such a thorough job that the treated wastewater is reused to replace fresh water and not for simply disposing off into the environment in a safe way. It is simply not good enough for treated wastewater to be used for watering lawns, an unnecessary demand.
