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.

Some thoughts
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
