Cool Water - Preventing Water Crises in Central Texas

  1. 1. Cool Water:<br />Blue Is The New Green<br />© 2010 Yudelson Associates<br />JERRY YUDELSON • YUDELSON ASSOCIATES • TUCSON, ARIZONA<br />
  2. 2. ©2011 Yudelson Associates<br />Learning Objectives<br />Learn about water scarcity issues in Central Texas region, water conservation strategies for buildings, factories, cities and homes<br />Understand how to incorporate water conservation concerns into design process such as rainwater harvesting<br />Review successful approaches to water conservation in Central Texas through local case studies<br />Be able to articulate options for new water re-use and supply technologies, including water efficient technology, retrofits and existing buildings. <br />
  3. 3. Key Take-Aways<br />Water is the next big (green) thing<br />International experience and technology can be adapted here<br />Major new opportunities: owners, designers, facility managers, entrepreneurs and contractors<br />©2011 Yudelson Associates<br />
  4. 4. Why Water?<br />Water: 21st Century oil<br />Freshwater supply limited<br />Population/urban growth: large water footprint<br />Global warming hits water<br />Major droughts since 2006<br />Water efficiency leads to conservation outcomes<br />©2011 Yudelson Associates<br />
  5. 5. Water Is the Oil of the 21st Century<br />Resource conflicts<br />Existing water sources fully allocated<br />Next urban/rural battleground<br />© 2011<br /> Yudelson Associate<br />
  6. 6. Water is the Oil of the 21st Century<br />© 2011<br /> Yudelson Associate<br />
  7. 7. Freshwater is inherently limited<br />No more water since Adam & Eve<br />Usable freshwater a tiny fraction<br />Much is too polluted to drink<br />Aquifer depletion reduces water supply<br />©2011 Yudelson Associates<br />
  8. 8. Freshwater <br />© 2011<br /> Yudelson Associate<br />
  9. 9. Water Footprint<br />© 2011<br /> Yudelson Associate<br />
  10. 10. Global Warming<br />Much of world’s summer water supply from snowmelt<br />Changes in climate = smaller snowpack, larger spring runoff, greater flooding, reduced summer stream flows<br />Water pricing for conservation will be huge issue<br />© 2011<br /> Yudelson Associate<br />
  11. 11. Water Conservation vs. Water Efficiency<br />© 2011<br /> Yudelson Associate<br />
  12. 12. Water/Energy Nexus<br />Hydropower still important<br />Water supply <=> energy use <br />Energy supply <=> water use<br />By 2020s: Not enough water for energy, or energy for water!<br />©2011 Yudelson Associates<br />Lake Lanier, Atlanta, GA<br />
  13. 13. Major Droughts Since 2006<br />In the U.S.<br />Atlanta<br />South Texas (Austin/San Antonio)<br />California<br />In Australia<br />Every major city<br /><ul><li>Murray-Darling basin</li></ul>© 2011<br /> Yudelson Associate<br />Murray-Darling, Australia’s Largest River<br />
  14. 14. Water Conservation vs. Water Efficiency<br />Conservation means less total use<br />But efficiency does not guarantee conservation<br />Behavioral change is equally important<br />Water conservation: some unintended consequences<br />San Francisco: $14 million for bleach<br />©2011 Yudelson Associates<br />
  15. 15. Australia<br />20 million people<br />Most live near the coasts<br />Except for tropics, country is quite dry<br />Global warming has moved storm tracks south<br />Biggest drought in 117-year recorded history since 2005<br />©2011 Yudelson Associates<br />
  16. 16. Australia<br />Coordinated response by national/state governments<br />$13 billion plan ($650 per person)<br />Water restrictions in all urban areas<br />Product innovations<br />WELS rating mandatory for products since 2006<br />Product innovations come out of labeling<br />©2011 Yudelson Associates<br />Rainforest in Tasmania, Australia<br />
  17. 17. Australia<br />Plumbing industry front and center<br />Large water utilities recycle water, even for domestic use<br />Public cooperation vital<br />Desalination - viable option<br />©2011 Yudelson Associates<br />Falcon water-free urinals<br />
  18. 18. Australia: Lessons Learned<br />In a crisis, everything’s on the table<br />Easier to do big things politically<br />System favors (big) long-term solutions<br />Don’t neglect public participation<br />New technology can be mandated in crisis<br />Exotic solutions can be tried and evaluated<br />© 2011<br /> Yudelson Associate<br />Murray-Darling — Australia’s Largest River<br />
  19. 19. Germany<br />80 million people<br />Leader in adapting to global warming<br />Focus on rainwater harvesting codes<br />New technologies emerging for gray water reuse<br />©2011 Yudelson Associates<br />Top: Heidelberg, Germany<br />Bottom: Water House, Pforzheim, Germany<br />

  21. 21. Driving Forces<br />Water shortages/droughts in many states<br />Financial/regulatory incentive programs<br />Green certification programs such as LEED<br />Rising costs for water supply and sewage treatment<br />Stakeholder concerns; political and regulatory changes<br />©2011 Yudelson Associates<br />
  22. 22. Inhibiting Forces<br />Water is still cheap in most areas<br />High-water-use lifestyles still preferred<br />Unintended consequences<br />Agency revenues drop<br />Sewers and drain lines don’t flush<br />Codes hard to change<br />Lack of whole systems thinking<br />©2011 Yudelson Associates<br />
  23. 23. Where Does This Leave Us?<br />A very dynamic future: much opportunity<br />New technologies, systems, approaches<br />New products coming to market constantly<br />Larger questions?<br />What about water for the environment?<br />©2011 Yudelson Associates<br />
  24. 24. Some Opportunities?<br />“Green plumbing” jobs<br />Building fixture retrofits<br />NEWater reuse/recycling systems<br />New specialties<br />Whole systems engineer<br />Using less-than-potable sources<br />© 2011<br /> Yudelson Associate<br />
  25. 25. The Future is Green (and Blue), But…<br />If we want to score, we run to where the ball is headed, not to where it is.<br />Ask yourself: how green (and blue) will the built environment be in 2015? What will be the Next Normal?<br />How can I participate in the water revolution?<br />Spain Wins FIFA World Cup 2010<br />©2011 Yudelson Associates<br />
