    • Trevor Hill Global Water Resources Opportunities for Designing our Water Future Infrastructure and Information
    • Source: UN FAO ( http://www.fao.org/nr/water/art/2008/wateruse.htm ) and UN “World at Six Billion” By 2025, 1.8 billion of the world’s projected 8.9 billion people will be living in countries or regions that are experiencing “absolute water scarcity”, and two-thirds of the world population could be under conditions of water stress
    • The Reality of Water Pressures 2001 2002 2004 2003 2006 2005 2008 2007 2009 2000 1999
    • Water Sustainability Source: Milly, et al, “Stationarity is Dead: Whither Water Management?”, Science, 1 Feb 2008 “ The world today faces the enormous, dual challenges of renewing its decaying water infrastructure and building new water infrastructure. Now is an opportune moment to update the analytic strategies used for planning such grand investments under an uncertain and changing climate.”
    • Arid City of the Future “ In the20th century we built this water system and it brings incredibly high quality potable water to our homes, and we use it to drink and to flush our toilets and to water our lawns. It's a crazy use of a wonderful resource.” Peter Gleick, Fresh Air, WHYY, November 27, 2007
    • Arid City of the Future “… figuring out how to match the quality of the water that we have with the quality of water and the different uses that we need is part of this new thinking for the 21st century.” Peter Gleick, Fresh Air, WHYY, November 27, 2007
    • Arid City of the Future Source: USEPA
    • Infrastructure – Dual Reticulation
    • Water Efficiency of Recycled Water
    • Power Efficiency of Recycled Water Source: R.C. Wilkinson, University of California, Santa Barbara, 2007
    • Arid City of the Future Desalination Reuse
    • The Need for Data “ A key to improving efficiency is understanding where, when, and why we use water.” Source: P. Gleick, Roadmap for sustainable water resources in southwestern North America, PNAS, 14 Dec 2010
    • Smart Grid for Water Utility Consumers Information Data CMMS CIS GIS SCADA

    • Water Sustainability “ As a species, we have survived knowing very little about our water systems. We have always known where to find it and how to use it, but we never gained an intimate understanding of how to preserve or sustain these systems. “ But we will not have the luxury of this ignorance in the future.” Source: Water – A Global Innovation Outlook Report, IBM, 24 March 2009
