  1. Is our water future sustainable? Competition for scarce water resources Jeff Fulgham CSO Banyan Water

  2. GE to Banyan Water? “Water will become the single most important physical-commodity-based asset class” — Citigroup Today Water scarcity, bills, damage growing Property owners underserved by fragmented vendors Tomorrow Water Steward: software & service for smart, remote mgmt. • Unique: • Team of industry leaders • Solution: 1st layer, smart grid for irrigation • Pipeline for rapid growth

  3. Today’s focus Global Water Challenges Sustainability = risk mitigation Water Sustainability Enablers Sustainable Examples

  4. Global water challenges Assuring sustainable quantity Improving water quality Reducingenergyconsumption Can we change the outcome?

  5. Global water challenges Assuring sustainable quantity Improving water quality Reducingenergyconsumption Can we change the outcome?

  6. Demand >>> Supply Decrease demand 5,800 Gap Available supply Increase supply 2020 Global water withdrawals Billion m3 6,000 5,000 4,500 4,000 3,000 2,000 1,000 0 2010

  9. Global water challenges Assuring sustainable quantity Improving water quality Reducingenergyconsumption Can we change the outcome?

  10. Power production Oil Sands UnconventionalGas Mining Energy production is thirsty! Energy 11

  11. Alternate energy sources …carbon-water tradeoff?

  12. Water use Air quality Land disturbance Related to frac process Public concern over environmental issues Degree of public scrutiny* Wastewater treatment/ disposal Water availability Produced water Land clearing Venting or flaring from completions/ workovers Frac water Quantity Source Low High Truck traffic Regional ozone attainment Water rights Chemical composition of frac fluid * Relative to conventional gas development Water issues take forefront of national debate

  13. “Global water scarcity is one emerging risk that all companies should be focused on – and one about which investors need information. The combination of rising global populations, rapid economic growth in developing countries, and climate change is triggering enormous water availability challenges around the world. Electric power generators, food producers, and other water-intensive industriesare especially vulnerable, both in their operations and their extensive supply chains.”

  14. Water risk factors

  15. Regulatory risks • Wastewater reuse • Se, As, Hg removal • Zero Liquid Discharge • Cooling tower reuse • Water stewardship • Biological control Water rights Discharge options Tariffs Waste disposal Stringent regulations Permitting Emerging pollutants Ash ponds

  16. Physical/Operational risks • Alternate sources of supply • Wastewater reuse • Desal … brackish, seawater • Muni/industrial wastewater reuse … BOO • Greywater expertise • Cooling water treatment automation & control Availability Demand Quality Knowledge gaps Access/ Allocations Outage impacts Shift from air to water Efficiency

  17. Reputational/Social risks Brand impact Supply chain • Site-specific water sustainability plan • CSR support • Metrics & monitoring • Remote monitoring & diagnostics • Environmental stewardship • Aqueduct project consortium • “Credit” for reuse Media sensitivity Long-term fate Compliance violations Employee impact

  18. Financial risks • Broader approach • Build, Own, Operate options • Value Generation Process • Water reuse • Integrated Water Services • Alternate/renewable energy • Waste to Value projects Direct costs Energy costs Indirect costs Waste treatment Water pricing “Next best” alternative Incentives Bond rating

  19. Water sustainability enablers Technology Economics Policy

  20. Water sustainability enablers Technology Economics Policy

  21. Microfiltration Ultrafiltration Reverse Osmosis 0.1nm 1nm 10nm 10mm 100nm 1mm Conventional Filtration Membrane technologies Removing contaminants from waterRelative particle size Staphylococcus Bacteria Pseudomonas Influenza Virus H2O Na + Sucrose Hemoglobin Bacteria Human Hair (80 mm) 0.1nm 1nm 10nm 10mm 10mm 100nm 1mm 100mm

  22. Extracting value from wastewater Efficient separations “Waste” stream Water Energy Salts Metals Nutrients Waste Ponds Disposal Well • Increasing Value for Recovery • Water priced at true cost to supply, encouraging reuse • Energy and materials cost expected to trend upward What Drives Reuse? Past: Water scarcity and environmental regulation Future: Value recovery & continued regulation

  23. Water recovery & energy reduction 70-85% Recovery 98% Recovery Beneficial Use Produced Water Membrane Based Systems Thermal Evaporation, Crystallization, Bio Polishing Waste Water Recovery systems Wastewater to value

  24. 2003 Advanced desalination roadmap … RO processes New elements Waste heat water recovery Nano high flux membranes Cost/m3 2010 2012 2016 2020 Continued cost reduction

  25. Water sustainability enablers Technology Economics Policy

  26. High scarcity, low cost … where is the motivation to conserve? Does the price of water reflect its true economic value? Renewable water resources per capita Total water + wastewater cost per m3 by country

  27. Water sustainability enablers Technology Economics Policy

  28. Incentives & policy can drive change Beijing: 100% reuse by 2015 Alberta: 70-90% reuse by 2012 Spain: 11% reuse today … 40% by 2015 Saudi Arabia: 11% reuse today …65% by 2016 Israel: 85% reuse today 90% by 2016 Water data source: GWI Renewables data source: REN21 Many countries taking action … US currently stalled

  29. We never know the worth of water till the well is dry. ~Thomas Fuller Jeff@banyanwater.com Twitter: @H2OSustain
