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.

The OfferMission:“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

Objectives

1. Identify impediments (real or imagined)2. Define a common terminology3. Gather best practices, state of the industry

information, and case studies4. Review California (Title 22) – NOT adopt5. Create Advisory Panels6. Conduct a scoping process to provide

recommendations to ADEQ/ADWR7. Develop a road map to potable reuse in Arizona

Process

Form the Steering CommitteeConduct Advisory Panels–Water Quality Regulations & Guidance–Public Perception– Technology Toolbox– Emerging Contaminants (APEC)White Paper(s)

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

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

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
