Participatory Aquifer Mapping

Citizen Aquifer Map

OUTPUT

● Aquifer Map

● Water Balance

● Scenarios

OUTCOME

● Water Literate Citizenry – citizen monitored map

● Ownership of data

● Identify and facilitate sharing and adoption of Best Practices

● Not just Yamalur Watershed

● Engagement with governance

Actors

● RWAs/Citizen Groups● Schools● Businesses● Service Providers – Water Quality Test labs,

Camera Inspections, Borewell diggers, Tanker operators, Well diggers

● Government Institutions/Researchers – KSPCB, CGWB, DMG, ATREE, IISc, BWSSB, GSI ...

Mechanisms

● Sharing of existing data with/from citizens – eg. Borewell logs, Camera inspection reports

● Interviews, Questionnaires● Tests on site – SWL, Yield tests, Water Quality

tests● Automated instrumentation : Weather Station,

Automated Water Level Sensor● Communicate through

● Events● Facebook, YouTube, ... Social Media

Data About

● Borewells/Open Wells● Lakes● Land Use● Rainfall ● Rainwater Harvesting – Storage and Recharge● Water Demand● STPs and waste water reuse

BOUNDARIES

GROUNDWATER PROSPECTS MAP (2000 - 2002)

Borewell/Open Well Data - Static

● When was borewell/open well dug ?● Depth of casing● Level at which water was struck● When did it go dry ?

Data Collection – Open Wells

- Site visits- Conversations- Old Survey Maps

Camera Inspection Report/Borewell Logs

● DETAILS OF BOREWELL

● Dia of Borewell : 6½” inch.

● Depth of casing : 60 ft.

● Depth of Borewell : 770 ft.

● Static Water Level : 400 ft.

● CAMERA INSPECTION REPORT

● Camera Inspection was conducted on : 24.11.2014

● Horizontal Fractures was encountered : 135,268,326,387,430,463,527,536,580,590, 600,611,620,625,643,710,727,730.

● Recommendation: Suitable for Hydro-Fracturing

What we found

● Nobody seems to acknowledge the presence of Open Wells – at least 14 Open wells in the Watershed !!

● Very difficult to get data on Open Wells – nobody knows/remembers

● Borewell logs not asked for – not maintained

● Service providers reluctant to share data. In some cases do not maintain data

● Borewell Farms

Data Collection

Open Wells/Bore Wells - dynamic

Collected 4 times in a year● Static Water Level● Discharge per hour● Total extraction in a day● Water Quality

SWL Measurements

Pump Tests done on site

Water Quality - Open Well in School

Events – bring your Water Sample

Surveys – engagement heavy

Automated Water Level Sensor

What we found

● Difficult to find ideal conditions for testing – borewells not pumped for 24 hours

● Neighbouring borewells are always pumping● Varying yields● Great interest to understand what it all means● Problems with Instrumentation – water level

sensor breaks down easily/gets stuck in borewell/ faulty beeps

● STP water output reports available easily

Data – Lakes (Static and Dynamic)

● Area● Location● Catchment/ Inlets/Outlets● Quality, Water Level

Data Collection

Lakes - Quality

Some of the outcomes ...

Citizen-KSPCB Dialogue

Data – Rainfall

Data - Recharge Wells

Data Collection – Recharge Wells

What we found

● Well diggers very keen to contribute data● Places where hard rock is found● Recharge Wells that yield water

Data – Land Use/No of borewells

LandUse / Borewells

Data – Water Demand and STPs

● Water Balance for the MicroWatershed● Rain (stored and recharged)● Groundwater extraction● Treated waste water for reuse● Domestic/Industrial/ Small shops demand● Generated waste water

KSPCB – list of STPs

Demand Approximation

● Attempted with WARD population + Panchayat population

NEED HELP !!

THANK YOU !!

Automated Water Level Sensor

Community / Communication

● Meetups● Lake Walks● STP/Lake visits● Government Schools – Kaikondanahalli ● Private School - Prakriya● OBL, KSWN, FOL● ELCITA / WIPRO / other City events● Bellandur Buzz● Tanker Operators/ Borewell diggers● Facebook, Blog, YouTube● ATREE, GSI, CGWB, DMG, ...
