Poway residents are about to see their water costs climb, with the City Council signing off on a five-year plan that bumps rates nearly 26% from 2026 through 2030. The schedule starts with a 9.9% jump in 2026, followed by 4% increases each year after that. City officials say the extra money is needed to keep up with rising wholesale prices and to help pay for the city’s Water Infrastructure Improvement Program. The new charges will first show up on bimonthly bills mailed on or after Wednesday.
Council Adopts Five-Year Schedule
According to the City of Poway’s Proposition 218 notice, the council held a public hearing on Tuesday and approved a rate schedule that phases in changes from 2026 through 2030. The plan shifts customers to a uniform volumetric rate and is structured, the notice explains, to sustain daily operations, keep reserves healthy and support long-term capital projects. The council’s action and the detailed rate tables are part of the public record in that notice.
What the increases mean for your bill
The vote was not unanimous. Council members backed the five-year adjustment, with one dissenting vote from Councilmember Jenny Maeda, who argued that the plan could land hardest on low-income households and customers who use relatively little water. Under the adopted schedule, rates increase 9.9% in 2026, then 4% per year through 2030. City staff figures cited by The San Diego Union‑Tribune estimate that the average Poway water customer’s monthly charge will rise from about $302.69 before the vote to roughly $351.12 in 2026 and about $410.76 by 2030.
What’s driving the hikes
City officials point to several cost pressures behind the increases: higher wholesale charges from the San Diego County Water Authority, growing energy and treatment expenses and the need to bolster long-term financial reserves. The Water Authority has already adopted wholesale rates for 2026 to cover its own rising costs, and those are passed through to local water agencies. Regional wholesale adjustments like these have influenced rate moves throughout the county, according to officials, and the San Diego County Water Authority has posted its 2026 wholesale rate decision and background materials online.
Protests, Prop 218 and help for households
Under Proposition 218, Poway mailed notices to 15,946 property owners ahead of the hearing. To stop the increases, a majority protest of more than 7,973 written objections would have been required. City Clerk Carrie Gallagher reported that dozens of written protests were received both before and after the deadline, but the total fell well short of that majority threshold, according to The San Diego Union‑Tribune. As the new rates roll in, Mayor Steve Vaus has encouraged residents who are struggling with their bills to call 2-1-1 for information about assistance programs that can help with housing, utilities and related services.
What happens next
The city says the new uniform volumetric rate and the updated meter and commodity charges will appear on bimonthly bills mailed beginning on or after Wednesday. Additional pass-through adjustments tied to wholesale water, recycled water and energy costs will be layered in later, with at least 30 days’ notice before they take effect. For those wanting to dig into the details, the Proposition 218 notice includes a bill estimator and tables that break down charges for different meter sizes and customer classes through 2030, and the full notice along with staff materials remains available on the City of Poway’s website.
