Everything you need to know about water purifiers
Water purifiers contain different types of filters but what kind of contaminant does each type filter out? What should you look for when buying a water filter for your home? Posted on 01 Jul, 2013 11:00 AM

Pure, clean and safe drinking water isn’t available easily these days. Growing population, industrial development and environmental degradation are all causes for this. Given this situation, it becomes even more important for us to be aware of purification techniques and the available water purifiers in the market to ensure that our drinking water is of good quality.

Fight water-borne diseases before they happen
Diarrhoea, cholera and dysentery are often rampant after the monsoons. The state of Assam piloted a programme to teach people to prevent their occurrence rather than to treat the illness later. Posted on 25 Jun, 2013 11:07 PM

The monsoon brings with it water-borne diseases like diarrhoea, cholera and dysentery, which cause suffering and death. Although this is a recurring theme annually, not enough measures are taken to prevent this. The state of Assam decided to take some action in May of this year.

Delhi’s ground water hits rock bottom
Too many people, too much pollution and too little water – that's Delhi’s water supply situation in a nutshell. Posted on 20 May, 2013 12:40 PM

Green pastures and meadows, tall trees, lakes, wells and the river…those are my memories of Delhi. It wasn’t too long ago that one woke up early to the sounds of lawns being watered, children running off to school and people walking in the parks. A flurry of activity but quite different from what it is today.

Conference report: The Anil Agarwal Dialogue on "Excreta does matter", organised by Centre for Science and Environment on 4-5 March 2013 at New Delhi
Where will India get its fresh water from in the coming years ? What is the state of the sewage system in the country ? Posted on 12 Mar, 2013 03:23 PM

A close examination of these two issues shows that the water and sewage challenge is already grave and could get worse. With this as the backdrop, Centre for Science and Environment (CSE), a public interest research and advocacy organisation based in New Delhi, organised a two day conference called the Anil Agarwal Dialogue on “Excreta does matter”. The conference took place at the Jacaranda Hall, India Habitat Centre, Lodhi Road, New Delhi on 4 and 5 March 2013.

The dialogue aimed at furthering the agenda of CSE’s seventh State of India’s Environment report titled Excreta Matters. This report is a comprehensive survey of the situation of water and wastewater management in 71 Indian cities. The study found that most cities lack a basic policy direction on how best to tackle issues of demand, supply and treatment of water, and of management of sewage. 

The Dialogue being the first of its kind brought together a wide range of professionals, activists, practitioners, policy makers, academicians, researchers and administrators from the water sector. The event was aimed at drawing attention on the critical issues of how cities will get affordable and sustainable water and waste systems that can supply to all and take back and treat the sewage of all.
