Fiscal commission recommends 5% wastewater rate increase after $1M emergency repair exposes funding pressure
Summary
Deputy Director Adrienne Heineck told the Davis Fiscal Commission that a major emergency sewer repair and rising capital costs have left the wastewater fund below its reserve target; the commission unanimously recommended a 5% rate adjustment to council, effective May 1, 2026.
Deputy Director Adrienne Heineck told the Davis Fiscal Commission on March 1 that the city's wastewater utility is under financial pressure following an emergency pipe failure that required more than $1,000,000 in repairs and pushed capital expenditures above projections. She asked the commission to recommend a 5% wastewater rate adjustment to the city council, with the change to take effect May 1, 2026.
Heineck, who identified herself as deputy director of public works utilities and operations for the city of Davis, said the utility operates under a Proposition 218 five-year rate-setting framework and that staff performs an annual check-in before each scheduled adjustment. "We're going to be coming back with an update, because we've had some impacts to our utility," she said, explaining that timelines for several CIP projects shifted and supply and contractor delays increased costs.
The presentation outlined the utility's structure: an operations fund funded mostly by customer fees, and a restricted fund for connection/capacity fees that can be used only for system expansion. Heineck said about 90% of wastewater revenue comes from customer fees and described the residential and commercial rate components (fixed base, per-unit and volumetric charges based on winter water use and effluent strength).
Commissioners asked staff how the 5% figure was reached and whether the adjustment was already approved; Heineck said the 5-year cost-of-service study sets the schedule, the commission and then council review it each year, and staff can recommend a lower increase or none if conditions warrant. Commissioner discussion emphasized the legal requirement that rates bear a reasonable relationship to cost of service and the sensitivity of ratepayers to perceived over-collection.
On reserves and debt, Heineck said the wastewater fund has been drawing on reserves for planned multi-year projects and that the fund's reserve target is roughly $8,000,000. During the meeting she stated the reserve balance had been presented as about $9,000,000 in one slide and later described the current available cash for the fund as approximately $6,000,000, about $2,000,000 below the target; she said staff expected a short, planned drawdown and will propose updates in the upcoming rate study.
Commissioners also discussed when to use debt for very large projects; staff said debt is typically considered for projects on the order of tens of millions and that the city generally avoids using cash for projects exceeding roughly $20 million. Commissioners urged the staff to prioritize long-term cost savings when choosing CIP alternatives.
After discussion, the commission voted unanimously to recommend that city council adopt the 5% wastewater rate adjustment on May 1, 2026. Commissioner (speaker 1) made the motion and Commissioner (speaker 4) seconded; the motion passed with no recorded noes or abstentions in the transcript.
The recommendation will go to the city council for final action during the council's May rate adjustments; staff said it will share commissioner feedback with council and return with more detailed analysis in the near term.
