Achieving another milestone for the filtration project with completion of our Project Definition Report

Blog post

In November 2020, the Water Bureau will mark another major Bull Run Filtration Project milestone and submit preliminary planning and pilot study results to the Oregon Health Authority as part of the compliance schedule.

We’re excited to mark another major milestone for the Bull Run Filtration Project with completion of the Project Definition Report. The report documents outcomes from preliminary planning for the new filtration facility and pipelines that will be part of a more resilient water system.

“We’re proud of the work that went into meeting this important milestone. Finalizing our pilot study and preliminary planning is another big step for the team towards achieving our compliance schedule,” said David Peters, Bull Run Treatment Program Director.

Submitting our Project Definition Report and Pilot Project Report to the Oregon Health Authority is the first of three key dates in our compliance schedule:

  • Nov. 30, 2020: submit pilot study results and preliminary planning
  • Oct. 31, 2022: submit final construction plans and construction schedule
  • Sept. 30, 2027: water served meets surface water and Cryptosporidium treatment requirements

The Project Definition Report incorporates content from the March 2020 Draft Filtration Facility Overview, which kickstarted the facility design phase early this year. The Project Definition Report also includes key planning outcomes to identify preferred pipe routes to connect the future filtration facility to the existing water system. The pipe routes were selected after completing two years of field studies, engineering analyses, and community outreach. These routes will be a guide for pipeline design.

“We’ve completed a lot of careful planning to get to this point. Throughout planning, we used project values informed by the community to guide our decision-making and pick the best routes for the new pipes,” notes Ken Ackerman, Pipeline Project Manager.

Preferred routes for new pipes were identified using community feedback and the results of two years of engineering and field work.

The Project Definition Report is an important part of our compliance schedule. Our pipeline designer will also use this planning work as their starting point when they begin design in 2021.

“We’re excited to have our pipe designer on board later this year, and we’re looking forward to a busy two years of design work ahead,” added Ken Ackerman, Pipeline Project Manager.

We’ll continue to share project updates and use community input to inform decision-making as design for the new facility and pipelines moves forward.
