Saving waterGuide
Why are water bills going up, even when we use less water?
Mostly to replace aging pipes and to pay more for wholesale water, power and chemicals. When a whole town saves water, the price per unit can rise too, because much of a utility's costs are fixed. Saving still keeps your own bill lower over time. Watch for your rate notice: that is when you can protest.

Water rates in many towns now rise every year, on schedules set years ahead. In Santa Rosa, California, by our math, water is set to cost about 36% more per unit by July 2029 than before July 2025.[1] That is the price, no matter how much you use. So what is pushing prices up, and why doesn't saving water seem to help?
What is pushing water bills up?
Mostly the pipes. The cost of updating aging water systems is the main driver of most rate increases, according to the Alliance for Water Efficiency, a nonprofit that works with utilities.[2]
Why does saving water push the price up?
This is the part that feels unfair. A utility pays many of its costs whether a town uses a lot of water or a little. But much of its money comes from selling water by the unit. When a whole town saves, that money falls short, and the price per unit rises to cover the same costs.[3][4]
California lived through this in its five-year drought in the 2010s. After a state order to cut use by 25%, some water agencies struggled to cover their costs, and many raised rates. Customers asked why they were paying more for using less.[2]
So does saving water still pay?
Yes, over time. Using less lets a utility put off new supplies, pipes and treatment plants, and those avoided costs keep rates lower than they would be.[2] In Tucson, Arizona, 30 years of conservation left rates at least 11.7% lower than they would have been, by an Alliance for Water Efficiency estimate.[2]
Our take: keep saving. Your own bill is lower than it would be, and water you don't use stays in rivers and aquifers that fish and people share.
Can you push back, or get help paying?
- Watch your mail for a rate notice. Your city council or water board sets rates after a public hearing, and you can speak or write in.[5]
- In California, you can protest. Proposition 218, a voter-approved state rule, limits rates to the cost of the service. If more than half of affected properties protest in writing before the hearing ends, the increase stops.[5][3]
- Can't pay? Call your utility and ask for a payment plan.[5] In California, the Water Shutoff Protection Act led utilities such as Petaluma to write a policy on shutoffs, payment plans and disputes.[6] Ask for yours.
In Sonoma County
Santa Rosa's adopted increases, year by year. Water rises faster than sewer.
Method: each July's increase added on top of the last.[1] Water increases can change with the wholesale price. Data and method.
- Santa Rosa's reasons: replacing old pipes before they break, protecting water quality, preparing for climate change and disasters, and paying more for wholesale water, power and chemicals.[1]
- Wholesale water: many cities here buy water from Sonoma Water, the regional water agency. It charged cities about 8% to 9% more for 2026-27.[4]
- Petaluma: raised most bills about 6% in July 2026.[6]
- Sebastopol: water and sewer rates rose 37% in July 2024, after its 2019 rates did not plan for how much people would conserve.[3]
What it means for you
- Open the rate notice when it comes. It is the moment your voice counts most.
- Check your own use too. If your units went up, see why is my water bill so high for a meter check.
The price of water follows the price of pipes. What you can still change is how many units you buy.
