Process of Aquifer Mapping
- 4. 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
- 5. 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 ...
- 6. 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
- 7. Data About ● Borewells/Open Wells ● Lakes ● Land Use ● Rainfall ● Rainwater Harvesting – Storage and Recharge ● Water Demand ● STPs and waste water reuse
- 9. BOUNDARIES
- 11. GROUNDWATER PROSPECTS MAP (2000 - 2002)
- 12. 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 ?
- 14. Data Collection – Open Wells - Site visits - Conversations - Old Survey Maps
- 15. 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
- 16. 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
- 17. Data Collection
- 18. Open Wells/Bore Wells - dynamic Collected 4 times in a year ● Static Water Level ● Discharge per hour ● Total extraction in a day ● Water Quality
- 19. SWL Measurements
- 20. Pump Tests done on site
- 21. Water Quality - Open Well in School
- 22. Events – bring your Water Sample
- 23. Surveys – engagement heavy
- 24. Automated Water Level Sensor
- 25. 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
- 26. Data – Lakes (Static and Dynamic) ● Area ● Location ● Catchment/ Inlets/Outlets ● Quality, Water Level
- 27. Data Collection
- 28. Lakes - Quality
- 29. Some of the outcomes ... Citizen-KSPCB Dialogue
- 30. Some of the outcomes ... STP/Lakes – Bio remediation study visits
- 31. Some of the outcomes ... STP/Lakes – Bio remediation study visits
- 32. Some of the outcomes
- 33. Some of the outcomes ... urbanlakes.org
- 34. Data – Rainfall
- 35. Data - Recharge Wells
- 36. Data Collection – Recharge Wells
- 37. What we found ● Well diggers very keen to contribute data ● Places where hard rock is found ● Recharge Wells that yield water
- 38. Data – Land Use/No of borewells
- 40. 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
- 41. KSPCB – list of STPs
- 42. Demand Approximation ● Attempted with WARD population + Panchayat population NEED HELP !!
- 43. THANK YOU !!
- 44. Automated Water Level Sensor
