8 Global and National Update

9 Global Report: Australia 10+ years of serious drought ( ): Invested ~$10 billion in reuse and desalination Perth: climate-independent water supply Two years record rainfall in the east ( ): Public pushback against costs, desalination, potable reuse National Goal: 30% Reuse by 2015

10 Global Report: Singapore Relied on imported water from Malaysia Heavy investment in desalination, reuse, and stormwater catchment for diversity Have achieved >30% Reuse

11 Global Report: Europe >3, projects Adapted fromaquarec EU Project, 2006 Trend for diversification: 75% for agricultural irrigation 6% for aquifer recharge 6% for urban uses 6% for environmental enhancement 6% industrial uses

12 Global Report Saudi Arabia $11 B investment in water and used water plants announced in July 2012 Goal of 11% supply from reuse Israel >80% household waste recycled (105 BG/year) Primarily used for agriculture (>50% of irrigation supply) China Current water supply: 163 trillion gallons/year 2030 water demand: 216 trillion gallons/year 80% of reclaimed water for agriculture and power plants

14 US U.S. Report Of 34.9 BGD municipal effluent in the U.S. only 5-6% is reclaimed

15 NAS Report on Water Reuse 32 BGD of wastewater discharged; 12 BGD to oceans Reuse could directly augment nation s total water supply Emphasized importance of multiple treatment barriers No demonstrable difference between technology and environmental buffers Risk of exposure to chemicals and pathogens: No greater than some drinking water supplies Use of indirect and direct is not productive Suggested EPA evaluate pros and cons of national regs. Identified research needs

16 US U.S. Report Industrial Reuse workshops, 1/2013 briefing for Congress National database scheduled for 2013 completion California A big gyear for legislation: Water Recycling Act of 2012 Bio cremation Potable Reuse Arizona Recommendations from Governor s task force

17 Florida Reuse A leader in reuse for years More reuse than any other state (by volume) Struggling with numeric nutrient criteria

25 Texas Reuse A Big State with Big Challenges Population doubling in 50 years More frequent / severe drought Project permitting harder than it used to be and Big Solutions: Reuse to be 14% of all new water supplies Desalination to be 3% of all new water supplies

26 Texas Reuse Great history of water reuse and desalination: El Paso San Antonio Dallas Trinity River Authority Austin North Texas Municipal W.D. Fort Worth (and others) New and very diverse projects: Tarrant Regional Water District: Wetlands Corpus Christi: Aquifer Storage & Recovery Odessa: Desalination Big Spring: Potable Reuse

27 Potable Reuse

28 Potable Reuse Congratulations to Texas! Need to stop pretend it s not already happening Need education about the complete water cycle ALL WATER IS REUSED! We all live Downstream!

29 Leadership & Communication

30 Leadership & Communication Time for talk is over the nation needs water now We need to be strong in the face of opponents and misinformation STICK TOGETHER!!! Communication: We need consistency and common language Congratulations to you all, but there is a lot left to do! Role of WateReuse Texas is critical
