Project Schedule

The Portland Water Bureau’s enhanced corrosion control plan was approved by the Oregon Health Authority (OHA) in 2016. This plan outlines the interim actions the bureau will take until enhanced corrosion treatment is in place.

  • Water Quality Corrosion Study: The study to determine the main causes of lead in Portland’s water system was completed in April 2017.
  • Submit recommendations to OHA: The results of the study were reviewed, and consultations with OHA resulted in recommendations for further treatment to Portland City Council in June 2017.
  • Corrosion Control Treatment Pilot Study: The study evaluates the different treatment potentials and is the first step to implementing improved corrosion control. It is currently underway and will be complete by June 2018.
  • Corrosion Control Treatment Facility Design: The design for a new treatment facility will begin by August 2018.
  • Corrosion Control Treatment Facility plans: The plans will be submitted to and reviewed by OHA by April 2020.
  • Corrosion Control Treatment Facility Construction: Construction will begin in January 2021 and will be complete by April 2022.
