About Arghyam’s GW-SAN Nexus Research Programme

This Groundwater- Sanitation Nexus Research Programme has been developed to deepen the understanding of linkages between ground-water and sanitation in the Indian context, and move towards an integrated approach. At present, the empirical evidence or knowledge about the linkages between groundwater and sanitation, is limited. The GW-SAN Nexus programme aims to bridge some of these knowledge gaps through pure and applied research, and by consolidating existing knowledge on this and related subjects.

Water mafias do not comprise only independent, small-scale players operating outside the state but also large-scale utility companies, which too operate through the water mafia and its strategies.

Water tankers are a common sight in most Indian cities and so are tanker businesses that extract and deliver groundwater via trucks or tractors to hundreds of residential neighbourhoods at a negotiated price. Most of these are informal or unauthorised.

Who are the water mafia and how do they operate?

With all the disappointing stories of Bangalore’s disappearing lakes, Jakkur Lake is a shining example of how urban water can be managed sustainably.

Jakkur Lake sits nestled behind the bustling Hebbal Highway that leads to Devanahalli International Airport. A pristine, quiet spot of nature in the midst of Bangalore, this lake stands testimony to the potential that exists to manage urban water sustainably, and in an integrated manner.

This event in Bangalore brought together children, people, photographers and cartoonists -- all for the love of their lake!
The morning of the Kere Habba on February 21, 2015, saw over 30 volunteers coming in as early as 7 a.m. and setting to work stringing festoons and paper lanterns between trees, sticking event posters, and more. Almost all the decorative items were home made by the children and adults. Snehadhara Foundation did likewise with sketches and artefacts painstakingly done by their children. Many hands made for quick work and it was all done in a couple of hours.

Hi All,

I need guidance on whether we need slotted piping/casing for our borewell or not? What are pros and cons for this?

The pump was stuck and was fished out through steel cable after cutting the water supply pipe. The scanning report says that there are loose bolders in the first 200ft of 1100ft borewell which can cause problem in future so as a solution, we have put slotted pipes till the bottom.

I have a ten acre plot in southwest of Bangalore with a borewell that yielded 2000gph till 2012, when it went dry. I dug a new borewell, after consulting a geologist,at a distance of 200', south of the existing one, last year. It yielded around 8000lit/hour till last week and now water comes in jerks and it seems it too may stop any any time. I have dug around 4 pig bits (20'X20'X10') at distances of about 100m from the borewells which catch rain water and retain them till Dec. only for the purpose of recharging the borewell ( assuming that I recharge my borewell).

Declining groundwater levels and increasing maintenance costs are the norm for most people these days, but residents of Rainbow Drive are exceptions.

"Just having the people of Delhi look at their water meters everyday will enable the city to deal with its current water supply", said K.P Singh.

He should know.

Singh is a resident of Rainbow Drive, a bungalow community in Bangalore. Led by him, the society has revolutionised its water availability from chronic scarcity to self-sufficiency.
