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

Harvesting and using roof-top rainwater - Part 2
Are the filters used for rainwater harvesting easy to maintain? More importantly, how efficient are they in terms of minimising the waste water that flows out? Posted on 22 Jun, 2013 05:18 PM

From unwieldy to understandable – transform the way you view data
People are afraid of data and numbers because it seems complicated. Visualising it will help you understand, form patterns and analyse better. Posted on 19 Jun, 2013 10:38 AM

IWP has over 200 sets of water data online. Of this, we have converted around 16 to an Excel format and will be adding more in the coming weeks for you to download. Use our Data Finder, a search tool for finding water data online, to search for this information.
