Corrosion Control Guidance for Arizona's AWP Program
When Arizona adopted its Advanced Water Purification rules in March 2025, it opened the floodgates for a new generation of direct potable reuse projects. But the new rules also created a need for updated guidance on corrosion control. Simon Horsley, an expert with 20 years of corrosion control expertise, will explain how new processes can affect water chemistry and distribution systems. RO and non-RO treatment processes raise important considerations for product water corrosivity, influenced by the extent of RO treatment and post-conditioning processes. Horsley will review corrosion control requirements and guide water system owners in developing a corrosion control study (CCS) for systems supplied by Advanced Water Purification Facilities. Key topics include system characterization, DPR-specific corrosion risks, desktop evaluations of water quality shifts, demonstration testing approaches, and strategies for implementation/monitoring.
