Bull Run filtration, water rates, and long-term debt
The Bull Run Treatment Program is the largest continuing capital story in the City record. Federal and state requirements drive filtration, while Council controls budgets, bonds, rates, and public accountability for a multibillion-dollar project.
What a Portlander needs to know.
The Water Bureau is building filtration to remove Cryptosporidium and other contaminants and to improve seismic and emergency resilience. The City says filtered water is planned for 2029.
After adoption of the FY 2026-27 capital plan, the City reports a $2.58 billion total program, including $2.46 billion for filtration. Customer rates, federal loans, and water-revenue bonds finance the work.
In May 2026 Council authorized bonds producing up to $525 million in net proceeds. Those bonds are payable from water-system revenue, connecting project cost and debt service to future rates.

Final construction cost, schedule performance, future annual rates, later bond sales, and responses to construction risks remain open.
Separate factual boundaries from policy choices.
These are neutral descriptions of arguments visible in the sourced record. They are not endorsements, ideology labels, or an attempt to force every dispute into two equal sides.
Regulatory requirement and project design
Filtration is being built to comply with drinking-water rules. Public debate still concerns design choices, cost control, and how the City manages delivery risk within that requirement.
Rates and intergenerational debt
Borrowing spreads costs across decades and can match payment to long-lived assets. It also commits future water revenue and increases debt service borne through rates.
Accountability during construction
Annual reports and project updates need to explain changes in forecast cost, schedule, contracts, contingency, and risk rather than only describe construction activity.
The decisions are chapters of one story.

Why this topic qualifies for a dossier10/12
This dossier clears the published 8-point threshold and the required continuity and consequence checks. The score determines eligibility, not prominence or a recommended position.
The story spans multiple meetings, matters, public bodies, or at least 90 days.
The outcome materially affects services, rights, public money, safety, the environment, or the city as a whole.
Understanding it requires connecting legal, financial, regulatory, intergovernmental, or implementation records.
The record contains divided votes, sustained testimony, competing official claims, litigation, or a consequential public dispute.
A decision, negotiation, implementation milestone, deadline, or measurable result still lies ahead.
A resident cannot understand the story accurately from one matter page or one roll call.
