Potable Reuse – A Changing Conversation

30 Years Ago: Deny (or)

Delay

15 Years Ago: Depend

5 Years Ago: Disguise

Today: Direct


Arizona’s Potable Reuse Triangle

Future Water

Supply Needs

Governor’s

Blue Ribbon

Panel

Steering Committee on

Arizona Potable Reuse (SCAPR)


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.


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


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


Process

Form the Steering Committee

Conduct 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
