2026 Fairfield Water Rates: What Changed January 1?

Fairfield approved a new water rate schedule under Resolution No. 2025-217, effective January 1, 2026. The adopted structure includes a fixed daily service charge and a separate water consumption rate.

Residential consumption rates depend on the property’s assigned water pressure or rate zone.

Residential Water Charges Effective January 1, 2026

One hundred cubic feet (HCF) is approximately 748 gallons. The fixed service charge is based on the number of days in the billing period, while consumption is calculated using the applicable water-rate zone.

Example: 10 HCF Over 30 Days

For a residential account in Zone 1–2:

• Fixed service charge: 30 days × $1.04 = $31.20.
• Water consumption: 10 HCF × $2.79 = $27.90.
• Estimated water charge: $59.10, before sewer charges, taxes, adjustments or other applicable items.

The same consumption in Zone 3–5 would produce a higher water consumption amount because that zone has a higher volumetric rate.

How to Find Your Fairfield Water Rate Zone

1. Open a recent water bill.
2. Find the Water Use Charge under the new charges section.
3. Find the water consumption measured in HCF.
4. Divide the water use charge by the number of HCF billed, excluding fixed charges.
5. Compare the calculated rate with the city’s published zone rates.

The city also provides a residential rate-zone explanation on its Water Rate Adjustments page.

Fairfield’s rate schedule includes annual changes through 2030. The city estimates that the average single-family household will see an increase of approximately $5–$7 per month each year, although the actual impact depends on usage and customer classification.

Why Is Your Fairfield Water Bill Higher Than Normal?

A higher bill may result from the January 2026 rate changes, increased consumption, a plumbing leak or a longer billing period. Before requesting a billing review, check both your water usage and rate-zone information.

Check Your Bill in Six Steps

1. Compare the billing period. Check the number of days covered by the current statement.
2. Review water use. Look at HCF consumption rather than only the amount due.
3. Check the water-rate zone. Confirm the applicable zone and published usage rate.
4. Inspect toilets and faucets. A worn toilet flapper or dripping tap can waste water without an obvious puddle.
5. Review irrigation equipment. Look for damaged sprinkler heads, stuck valves or unexpected watering schedules.
6. Use MyFMU to check trends. Compare current usage with past billing cycles, then contact Utility Billing if the increase remains unexplained.

The city provides additional guidance on its Residential Water Conservation page.

Request a Water Leak Adjustment

Fairfield has a water leak adjustment request process. Eligibility depends on the circumstances of the leak and the city’s review.

1. Locate and repair the leak.
2. Keep invoices, repair dates and supporting documentation.
3. Visit the official Water Leak Adjustment page.
4. Follow the current application instructions.
5. Provide the relevant account and repair information through the city’s authorized process.
6. Contact Utility Billing to confirm receipt and ask about the review timeline.

A leak adjustment is not guaranteed. Continue to follow any payment deadlines or arrangements while the request is under review.

Start or Stop Water Service in Fairfield

Customers moving into or out of Fairfield can request water and sewer account changes through Fairfield Municipal Utilities. Verify the exact service address before submitting an application.

Start New Water Service

1. Visit the Fairfield Water and Sewer Services page.
2. Select Start Utility Service.
3. Open the city’s current application for new service.
4. Enter the service address and requested start date.

6. Review any required deposit or connection arrangements.
7. Submit the application according to the official instructions.
8. Contact Utility Billing if you need confirmation of the service activation date.

If you are moving into a rental property, ask the landlord whether water is individually billed or included in another housing charge before opening an account.

Stop Water Service

To close an account, contact Fairfield Municipal Utilities at 707-428-7346 and request the official termination process.

Prepare the service address, account information, requested termination date and forwarding details.

Canceling an automatic bank payment alone does not necessarily terminate utility service. Confirm that the city has processed the account closure.

Late Water Bill, Shutoff Notice and Reconnection Fees

Fairfield water bills are due when received and become past due if the required amount is not paid by the delinquent date shown on the statement.

Under the city’s published policy, a 10% delinquent fee is added to an overdue balance. If payment is still not received, an additional processing charge of 0.5% per month may apply.

The city sends a shutoff notice before service interruption under its applicable procedures.

What to Do If You Receive a Shutoff Notice

1. Check the notice for the final payment date and amount due.
2. Sign in to MyFMU and confirm the account balance.
3. Call 707-428-7346 if you cannot pay in full or need to verify the notice.
4. Ask about available payment arrangements or other assistance.
5. Use an authorized payment method and keep the receipt.
6. Confirm with Utility Billing that any required steps to prevent or restore disconnection have been completed.

Published Disconnection Charges

The $35 after-hours amount applies under the city’s stated conditions. Confirm current charges directly before requesting reconnection.

Report a Water Main Break, Low Pressure or Sewer Problem

Fairfield Public Works Operations handles water distribution and sewer maintenance problems. Billing questions should go to Fairfield Municipal Utilities, while active infrastructure emergencies should be reported to Public Works.

How to Report a Water Leak

1. Find the exact address or nearest intersection.
2. Check whether water is escaping into the street, sidewalk or private property.
3. Do not touch damaged utility infrastructure.

5. For an after-hours emergency, call 707-428-7300.
