San Diego households already dealing with higher water bills may want to buckle up. A new long-range analysis presented to city leaders this week warns that rates might need to climb about 44% between 2028 and 2031, on top of increases already approved for this year. Council members were shown a financial model that city staff say reflects a one-two punch of rising wholesale costs and weaker water sales that together are squeezing the utility’s ability to cover day-to-day operations and long-planned capital projects.
The projection, described to council members as a roughly 50-page analysis, has already sparked attention in local coverage. The study forecasts about a 44.2% rise in water rates over four years and flags roughly a 15% bump in sewer rates in 2030 and 2031. According to CBS 8, the analysis was delivered to the City Council earlier this week.
What's in the study
The city has been working with outside consultants to model multi-year scenarios that balance operating costs, debt service, and the capital improvement program. The FY26 Water Financial Plan, Cost of Service and Rate Study prepared for the City of San Diego, lays out revenue requirements, cost allocations and the step-increase methodology staff used to test how much rates would need to change under different assumptions. The technical backbone of that work is detailed in the Raftelis report, which staff referenced during the briefing.
What’s driving higher bills
Staff and analysts point to passthrough charges from the San Diego County Water Authority, rising energy and construction costs, and lower water sales as the main drivers behind the projected hikes. City materials repeatedly note that a large share of San Diego’s supply is imported, which leaves local ratepayers exposed when wholesale prices spike. That vulnerability is a recurring theme in the city’s rate information and public notices available through the City of San Diego Public Utilities.
How much it could hit households
Under the scenarios staff discussed, the hit to typical residential customers adds up fast. Local reporting and the city’s budget analysis note that a household with a 1-inch meter, which now pays about $46.63 per month for service, would have seen that base charge rise to roughly $56.83 in January 2026 under previously proposed steps, and it would continue to climb under higher multi-year scenarios. KPBS lays out meter-size examples and earlier projections in more detail.
Officials' reaction and next steps
Council members responding to the briefing said they plan to spend the next 12 to 18 months combing through options before any fresh rate proposals go to a vote. Ideas on the table include cutting utility spending, hunting for new revenue sources and pressing the San Diego County Water Authority for relief on passthrough costs. Some councilmembers, including those who sit on regional water boards, have already publicly urged the authority to pursue structural fixes that could ease pressure on local customers.

What to watch
Residents should keep an eye out for follow-up briefings, budget committee hearings and any new staff scenarios that test alternatives to multi-year step hikes. The council is expected to receive updated financial projections and a menu of options before any new rate proposals are formally introduced or trigger a Proposition 218 notice to ratepayers.
