To remain in compliance, the Portland Water Bureau must submit the following to OHA by October 11, 2017:

  1. A description of which Cryptosporidium treatment technology the Portland Water Bureau intends to pursue.
  2. A detailed proposed schedule of when the treatment will be in place.
  3. Measures the Portland Water Bureau intends to take to reduce the risk of the public's exposure to Cryptosporidium until treatment is in place.
  4. A proposed sampling schedule for Cryptosporidium at the intake until treatment is in place.

During this period, the bureau will work with the Portland Utility Board (PUB) and Oregon Citizens’ Utility Board (CUB) to ensure the bureau's compliance proposal includes meaningful opportunities for community engagement.

Building a filtration plant to meet the specific needs of the Portland area will be a complex process, conducted over many years, with numerous decision points.

The Water Bureau will work with its community partners to ensure ratepayers remain apprised through plan development, design, construction, and operations.

The bureau’s Interim Measures Plan, due to OHA by October 11, 2017, will detail how the bureau will continue its protective measures while the filtration plant is being built.
