Download - Our Aquifers Our Water
Our aquifers, our water We have to understand it, we have to protect it
Boundaries we think in terms of : districts, wards, constituencies …
… our own property boundaries
… these dictate
what we consider“ours”…
Do the rules of these boundaries matter for
ground-water?How do we understand whats happening below our feet ?
Do we “own” our groundwater ?
Do we feel ownership for our groundwater ?
Other boundaries we don’t think of :
.. And we are in the Dakshina Pinakini Basin
(not Kaveri).

Two borewells right next to each other (near Halanayakanahalli Kere)
One yields and the other does notHold your ear to the non-yielding borewell and you
hear water flowing
The story of what happened when SJR Redwoods tried to dig a borewell….
How does a borewell look inside ?
Footage from a “camera inspection” of a borewell conducted by a citizen of
Bengaluru…..
These stories of your open and borewells are a
window to groundwater You have to become a part of
understanding it better…..
Groundwater :AquifersGroundwater resides in Aquifers :• Aquifers don’t respect property, political or administrative boundaries.
• Aquifers are a common-property resource. You or me or anybody don’t “own” it.
• Aquifers can be understood. They can be mapped, and how water flows in it, how much water it holds can be established. (We don’t have this understanding for ours)
• With this understanding and all our participation & stewardship Aquifers can be managed. (eg: Edwards Aquifer, Texas )
Aquifers
Aquifers and how they behave are determined by:• Geology of the place• Other Ecological characteristics – terrain, topography, watershed, rainfall
• Land-use changes we effect• Use of water from the aquifer & discharge of our waste-water

Aquifer mapping: The understanding we could get to…
…if you participate and share your stories, data, practices with the cityYou have to become a part of the process of mapping the
aquifer….
Eg 1: Data about your borewell
Eg 2: Your water quality stories…
A Platform to make this easy
Share your data and stories on this platform.
How can we make this platform useful to all of us ?
Thank you
