1 Embracing Water Supply Sustainability - The Role of Reuse in our Water Supply Portfolios Melissa L. Meeker, Executive Director WateReuse Association WateReuse Research Foundation

2 Thinking about Water Differently

3 Water Scarcity Risks Nearly 2 billion people live where access to clean and safe water is increasingly limited By 2030, there will be a 40% gap between water supply and demand In 2014, the global water crisis rose to a top-three business risk for impact and likelihood 70% of companies surveyed identify water as a substantive business risk US-based Fortune 500 companies: 94% face potential physical challenges 69% face reputational risks 80% 60% say it will affect their decisions on where to locate facilities indicate water will affect business growth and profitability within five years SOURCES: World Economic Forum 2013 CDP Water Report Bridging Concern with Action: Are US Companies Prepared for Looming Water Challenges?, Pacific 3 Institute and VOX Global 2014 survey of US-based Fortune 500 companies 3

4 Water is Food 30% of US water footprint is from meat consumption 2,000 gallons of water = 1 gallon milk 5,200 gallons of water = 2 lbs of coffee 2,900 gallons of water = 1 quarter pounder 250 gallons of water = 2 lbs of wheat 4

5 Water is Power Based on 2004 data-136 Billion gallons water used per day for cooling 2010 estimate approaches 200 Billion gallons per day Tampa Electric Company why look at alternative water supplies? Certainty in water availability Wastewater discharges Positive Public perception through conservation Partnership with local municipalities Help address cooling reservoir water quality 5

6 Water is Commerce 75,000 gallons of water to produce one ton of steel Car = 2,150 pounds of steel = 80,000 gallons of water 1 to 2.5 gallons of water = 1 gallon of gasoline 24 gallons of water = 1 pound of plastic 2x as much water to produce a plastic water bottle as the amount in the bottle 1,320 gallons of water = 1 pound of cotton 700 gallons of water = 1 cotton shirt 2,900 gallons of water = 1 pair of blue jeans Industrial water consumption makes up 22% of global water use 6

7 Local Connection: Fortune 500 Companies Nike - $19B Precision Castparts - $5.5B Lithia Motors 130 dealerships Intel largest for-profit employer 7

8 Local Connection: Northwest Food Processors Association (NWFPA) - food processing & packaging segments: fruits, vegetables, seafood, dairy, bakeries, specialty, juices and more. 75 processor companies and more than 350 supplier members. Sales in Millions 8

9 Local Connection Nation's leading generators of hydroelectric power, ranking second, after Washington, in net electricity generation from conventional hydroelectric power. 70% of Oregon's net electricity generation was from conventional hydroelectric power plants and other renewable energy resources. What impact will drought have on this energy source? 9

10 The Risk of No Water Society must recognize that water is crucial and deserves attention for the overall success of our Communities Economy Regional independence Societal acceptance of sustainability Water is absent from the discussion 10

11 One Water: Integrated Water Management

12 The One Water Solution A Sustainable Approach - Manage all water as One Water: Drinking Water Rain/Storm Water Groundwater Recycled Water Wastewater Conservation 12

13 One Water LA Plan Integration One Water Inclusion Innovation GREAT WATER CITIES SUMMIT

14 The Future is Bright in Meeting LA s Water Challenges GREAT WATER CITIES SUMMIT
