Addressing Climate Change through water use efficiency_Hari Hegde_2013

  1. 1. Promoting Water Use Efficiency across Urban Sectors to address climate change Setting the context December 13, 2013 1 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  2. 2. India is racing towards #3 Economy Real GDP 2006 $bn Estimated Real GDP 2050 $bn USA 12457 Japan 2829 Germany China 35165 USA 2829 27803 India China 2225 UK 2213 Japan France Brazil 2132 Italy 1720 Canada 6673 6074 1122 UK Germany S Korea India 3782 1119 Spain Brazil 5870 Russia 3603 804 France 787 759 Italy 3148 2061 Source: Dreaming with BRICs: The path to 2050; Goldman Sachs 2 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  3. 3. Effect of Climate Change on Water Resources Economy closely tied to its  Natural Resource Base   Water and Forestry Climate-sensitive Sectors  Industry, Agriculture National Action Plan on Climate Change (NAPCC)  Eight National Missions CII-TWI-BWSSB joint initiative  Improving water use efficiency in urban water sector 3 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  4. 4. India Moving towards Physical & Economic Water Scarcity Source: International Water Management Institute analysis done for Comprehensive Assessment of Water Management in Agriculture using Watersim model. 4 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  5. 5. Density of Population and New Groundwater Draft No Country in the World pumps as much ground water as we do …………. We already have 21 million wells and add another 1.0 million/year Groundwater Use in India Has more to do With population Density than the Availability of the resource 5 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  6. 6. As a Result ! Per capita water availability (m3/capita) 6000 5000 Water stress line (1700) 4000 Water scarcity line (1000) 3000 2000 1000 Water Availa bility (cum) 0 1951 1961 1971 Per capita available water resource 1981 1991 2001 2011 2025 2050 Per capita utilizable water resource (GW and SW)  Regions face growing demand-supply gaps.  Climatic variability is an addon stress.  Conflicting demands over a shrinking resource 6 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL

  8. 8. Engineering Industry- Water Efficiency Water saving potential in Indian industry  35 – 50 %  Excellent Potential to reduce, reuse and recycle 8 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  9. 9. Waste Water Treatment - Municipal & Industrial Domestic Wastewater  23000 MLD generated (300 Class I Cities and 345 Class II towns)  Only 6000 MLD is treated Industrial Wastewater  13000 MLD generated by 1,35,000 polluting industries  60% is treated (large & medium industries) Source: CPCB 9 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  10. 10. Water Scenario Bangalore Source of Water  Cauvery river, ground water Sewage  More than 90% sewage is drained in municipal sewer Rainwater  Average rainfall ~1000 mm/yr Major Water Distribution lines are under ground 10 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  11. 11. CII-TWI and BWSSB Activities to be undertaken Objective  Water audits in Industry, buildings /hospitals To Promote Water Use Efficiency across Urban Sector to Address Climate Change 11  Pre-feasibility studies for utilizing municipal sewage  Identification of doable projects on reuse of sewage  Information Dissemination and Capacity Building Programs © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  12. 12. Ecosystem Approach to Address the Climate Change WATER AUDITS (Industry and Buildings) ECOSYSTEM SECURITY SEWAGE RESUABILITY IMPACT ON WATER RESOURCE Supply and Demand Side Management SUSTAINABLE WATER RESOURCE 12 MINIMIZE IMPACT © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL Best Practices on Reduce, Reuse and Recycle CLIMATE CHANGE
  13. 13. CII-Karnataka Water Task Force  3 Key agenda of the CII – Karnataka Water Task Force –  Help Create “Water Sustainable Zones” within Bangalore  Launch „Karnataka State Water Network‟ with the support of GoK.  Hold “Annual Water Conference” on 12 March 2014  Study on „Integrated Urban Water Management‟ 13 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  14. 14. Conclusion Water conservation and management  Critical for urban sustenance Major sectors  Domestic  Commercial & Industrial buildings  Industry  Water intensive & SME’s Opportunities     14 30% water saving potential in industry 40-50% saving potential in buildings Augmentation of water resources Recycle & reuse of municipal water in industry © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
