How to Pay a Fairfield Water Bill Online, by Phone, Cash or Check

Fairfield customers can use MyFMU for online account management and the City’s pay-by-phone option for phone payment. If you are paying close to a deadline, choose a method that posts in time and save proof.

Open the official MyFMU portal

Use the official Fairfield MyFMU/SilverBlaze portal to view and pay your utility bill from a computer or mobile device.

Open MyFMU MyFMU info

Choose the right payment method

If you want to avoid the listed card processor fee, consider ACH, check or cash. If convenience matters more, card payment may still be useful.

Use pay-by-phone if you prefer phone payment

Call 866-207-6045 and have your payment method and utility account number ready.

Save confirmation

Keep the receipt number, payment date, amount, payment method and screenshot until your MyFMU account shows the payment correctly.

AutoPay warning: If AutoPay is already scheduled within 5 days, do not make a manual one-time payment unless Utility Billing tells you to. Otherwise, you may create a duplicate payment.

MyFMU / SilverBlaze Portal: What Fairfield Customers Can Do

MyFMU is more than a payment button. The City says the portal includes usage monitoring, bill comparison and 24/7 account access. This can help you understand whether a high bill is caused by real water use, a leak, or a payment/account issue.

Usage monitoring

Review detailed water consumption patterns and use them to spot unusual spikes.

Bill comparison

Compare the current bill with previous billing cycles to understand changes.

24/7 account access

Check balances, make payments and update information on your schedule.

Best MyFMU tip: Before calling about a high bill, check usage history and bill comparison. It gives you specific numbers to discuss with Utility Billing.

Fairfield Water Bill Payment Fees and Fee-Saving Tips

Fairfield’s MyFMU page says FMU no longer absorbs credit card fees. If customers register for AutoPay and pay with credit or debit card, a $2.95 per-payment fee is charged by the card processor. The same page says ACH, check and cash will not incur a fee.

Payment method	Fee note	Best use case
Credit / debit card AutoPay	$2.95 per payment processor fee listed by the City	Convenience when the fee is acceptable.
ACH	City page says ACH will not incur a fee	Best fee-saving automatic payment method.
Check	City page says check will not incur a fee	Good for non-urgent payment when processing time is acceptable.
Cash	City page says cash will not incur a fee	Useful for in-person payment when you want to avoid card fees.
Returned check / returned AutoPay	Returned payment fee listed as $25	Avoid by keeping bank details and available funds current.

Fee-saving tip: If you use AutoPay, ACH may be better than card payment because the City page says ACH does not incur the card processor fee.

Fairfield Water Leak Adjustment: What to Do Before You Call

If your bill is high because of a leak, do not only pay and move on. Fairfield’s water and sewer services page lists a leak adjustment resource, so customers should gather repair proof and ask what qualifies.

Check for silent leaks

Running toilets, irrigation leaks, soft ground, water heater leaks and crawlspace plumbing can increase usage.

Repair first

Keep plumber invoices, receipts, photos and dates. Adjustments usually require proof the issue was fixed.

Ask Utility Billing

Call 707-428-7346 and ask what documentation is required for a Fairfield leak adjustment request.

Compare usage in MyFMU

Look for a sudden spike compared with previous billing cycles. Use MyFMU bill comparison and usage monitoring before calling.

Document the repair

Save invoices, parts receipts, photos and the date the leak was fixed. If you repaired it yourself, write a short note explaining the repair.

Request adjustment guidance

Use the City’s leak adjustment resource or call Utility Billing before the bill becomes past due.

Leak adjustment Call Utility Billing

High-bill tip: A leak adjustment request is stronger when you can show usage spike, repair proof and the exact date the leak stopped.

Disconnect Help, Late Bill or Past-Due Fairfield Water Account

If your bill is past due or you received disconnect information, call Utility Billing before making a partial payment. The City has a disconnect information resource, and the right action depends on your account status.

Do this first: Call 707-428-7346 and ask the exact amount required, the deadline, and whether a payment arrangement, leak adjustment or refund/assistance option applies.

Confirm account status

Ask whether the account is only past due, already scheduled for disconnect, or needs immediate payment to avoid service interruption.

Ask which payment method posts fastest

If the deadline is close, confirm whether online, phone, cash or check payment will post in time.

Save payment proof

Keep confirmation number, receipt, date, amount, and the name of the representative if you called.

Low-income senior or disabled water refund

Fairfield’s water and sewer services section includes a low-income senior/disabled water refund resource. If this applies to your household, ask Utility Billing whether you qualify and what forms are required.

Refund resource

Water Service Problem, Street Leak or Active Issue in Fairfield

Billing staff can help with accounts, but active water, street or traffic signal problems may need Public Works Operations. The City’s Public Works page says to call 707-428-7407 for issues with water, streets or traffic signals.

Call Public Works Operations

Use this number for active water issues, street problems, or traffic signal issues.

Call 707-428-7407

What to report

Give the exact address, nearest cross street, what you see, when it started, and whether water is flowing, pooling or creating a safety issue.

Safety note: Do not stand in street flooding, near traffic, or near electrical hazards to take photos. Report the location first.
