The Future of Potable Reuse in Arizona A Changing Conversation

1. The Future of Potable Reuse in ArizonaA Changing Conversation Presented by: Timothy M. Thomure, PE, PMP Water Reuse Practice Lead HDR Engineering, Inc. President WateReuse Arizona Timothy.thomure@hdrinc.com ADVISORY PANEL ON EMERGING CONTAMINANTS May 17, 2013

2. Potable Reuse – A Changing Conversation 30 Years Ago: Deny (or) Delay 15 Years Ago: Depend 5 Years Ago: Disguise Today: Direct

3. Arizona’s Potable Reuse Triangle Future Water Supply Needs Governor’s Blue Ribbon Panel Steering Committee on Arizona Potable Reuse (SCAPR)

4. Governor’s Blue Ribbon Panel on Water Sustainability B.3 – Facilitating Indirect Potable Reuse (IPR) • Create an IPR Multi-Agency Steering Committee to further advance the use of IPR by developing definitions, guidance and a statewide policy for IPR, streamlining agency reviews, and incorporating new technologies. • Create an IPR Advisory Panel, reporting to the Steering Committee, to focus on the effectiveness and implementation of new technologies and field studies. • Open a rulemaking process to develop the regulatory framework.

5. The Offer Mission: “To promote the responsible stewardship of Arizona’s water resources through education and advocacy for the best use of all water supplies” Project Mission: “To guide Arizona water interests in identifying and mitigating impediments to potable reuse (real or imagined) within industry standards of practice” Committed funding

6. Objectives • Identify impediments (real or imagined) • Define a common terminology • Gather best practices, state of the industry information, and case studies • Review California (Title 22) – NOT adopt • Create Advisory Panels • Conduct a scoping process to provide recommendations to ADEQ/ADWR • Develop a road map to potable reuse in Arizona

7. Process Form the Steering Committee Conduct Advisory Panels • Water Quality Regulations & Guidance • Public Perception • Technology Toolbox • Emerging Contaminants (APEC) White Paper(s)

8. Schedule • Set up workshop on Technology in line with the WateReuse Technology Conference in May, 2013 • Set up workshop on Public Perception in line with the AZ WateReuse Conference in July, 2013 • Set up workshop on Water Quality Regulations in line with the WateReuse National Symposium in September, 2013 • Coordinate with APEC during upcoming meetings • Conclude this phase before January 2014

9. Tech Toolbox Outcomes • Not a “one size fits all” technology solution • Develop a table of treatment technology options with targeted results • Develop a decision support flow chart for treatment trains • Input starting point • Input desired outcome(s) • Support with case studies and prior work

10. “Stuck in the Middle with You” Water Quality Approach Make it Happen Approach Treatment Based Approach

11. Recycled Water in Arizona:Right Water for the Right Use DPR Environmental Uses Indirect Potable Reclaimed Water Energy Production

12. Some thoughts… • Make it “right” for AZ • AZ Informed by CA and TX processes • Take what we need and leave the rest • Judge a water by its quality, not its history • Know the risks  need better testing technology • Build a water quality framework for Arizona to provide predictable structure for future projects Discussion
