  2. The 5 “D’s” of DiscussingPotable Reuse 30 Years Ago: 15 Years Ago: 5 Years Ago: Today: Deny (or) Delay Depend Disguise Direct

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

  4. SCAPR Objectives • Identify impediments • Define a common terminology • Gather best practices, state of the industry information, and case studies • Track CA and TX efforts • Create Advisory Panels • Conduct a scoping process to provide recommendations to ADEQ/ADWR • Develop a road map to potable reuse in Arizona

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

  6. Tech Toolbox OutcomesMay 2013 • 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

  7. Public Acceptance OutcomesJuly 2013 • Build trust, which also means start early • Have a structure and a timeline for decisions • Use clear/consistent terminology • Make a compelling case for investment • Engage trusted experts • Cultivate trusted community champions Option 2 – Just wait for the crisis to hit…

  8. Water Quality OutcomesNovember 2013 • Framework Objectives • Performance-based • “Permit-able” • Flexible • Decisions… • Virus/Giardia/Crypto • Barriers • Monitoring/CCP • Diluent

  9. APEC StatusMay - December 2013 Unregulated compounds All aspects of the water cycle • Chemical compounds • Biological • Public education What do we need to know for potable reuse?
