Council accepts 2025 Bull Run treatment report as filtration work resumes; bureau outlines resilience and affordability concerns
Summary
Council accepted the Bull Run treatment projects 2025 annual report, heard staff explain why filtration (not UV alone) is necessary for resilience to wildfire and sediment events, and discussed bill impacts and affordability programs for ratepayers.
Portland City Council on Oct. 29 accepted the Bull Run treatment projects 2025 annual report, which updates the public on construction of a filtration plant and associated corrosion‑control work intended to meet federal and state drinking‑water requirements.
Claire Adamsick, council policy analyst and staff to the Transportation and Infrastructure Committee, said the committee recommended acceptance. Staff posted a water bureau memo responding to written testimony and reported written comments on cost escalation, forecasting for ratepayers, alternative treatment options such as ultraviolet (UV) systems, and community impacts from construction detours.
Water bureau engineering manager David Peters explained why filtration was selected and how it improves resilience. Peters said a major wildfire that burns part of the Bull Run watershed can send large volumes of sediment to reservoirs during subsequent rains; filtration removes turbidity and sediment and therefore provides resilience that UV disinfection cannot because UV does not remove suspended solids. He noted the city’s groundwater supplies have limited seasonal capacity and would not fully substitute for surface water during some emergencies. Quisha Light, interim director of the Water Bureau, and other staff noted the bureau is operating under a compliance agreement requiring filtration by September 2027; failure to comply risks regulatory enforcement and practical consequences for customers, including potential boil‑water orders.
Councilors raised affordability concerns for low‑income households and asked about discount and assistance programs. Light described ongoing pilot programs and a financial‑assistance menu designed to help customers who cannot absorb price increases. Councilors also discussed regional customer dynamics; staff said some neighboring utilities have pursued separate facilities and that regional agreements and emergency interties remain under discussion.
The committee report and staff comments noted schedule delays and cost escalation driven by inflation, tariffs and conditional‑use proceedings. The council vote to accept the report carried 10–0.
