Online payment

How to Pay a Fairfield Water Bill Online With MyFMU

Use MyFMU when you want more than a one-time payment. The City describes MyFMU as a newer utility portal with usage monitoring, improved interface, bill comparison, payment history and 24/7 access.

1

Open the official MyFMU page

Start from MyFMU / SilverBlaze or the official Fairfield utility portal.

2

Register or log in

The City says customers need to register on the MyFMU portal. Keep your account number ready before you start.

3

Use the portal for more than payment

Check balance, pay bills, compare current and previous billing cycles, review payment history and monitor water usage.

4

Save confirmation

After payment, save the date, amount, confirmation number and payment method until the portal shows the payment on the account.

High-bill tip: Use MyFMU usage history before calling. If the portal shows a sudden consumption jump, your call becomes easier because you can point to the exact billing cycle or usage window.
Phone payment

Pay a Fairfield Water Bill by Phone

Phone payment: Call 866-207-6045 and have your account number and payment method ready.
Phone pay item What to prepare User tip

Fees and AutoPay

Fairfield MyFMU Fees, AutoPay and Returned Payment Rules

Fairfield’s MyFMU information says the City no longer absorbs credit card fees. It also warns AutoPay customers not to make a manual one-time payment if it is within five days of the payment date because AutoPay will automatically deduct the balance due.

Fee / AutoPay item Official detail Actionable tip
Credit/debit AutoPay fee $2.95 per payment charged by the processor for credit/debit AutoPay. Consider ACH if you want to avoid card processing fees.
ACH/check/cash Payments via ACH, check or cash do not incur the listed processor fee. Use ACH for recurring payment when possible.
AutoPay timing Do not make one-time manual payments within 5 days of AutoPay date. Avoid duplicate payment risk.
Returned payment fee $25 fee added if check or automatic payment is returned. Returned payment must be replaced by cash, cashier’s check, money order or credit card.
Avoid duplicate payment: If AutoPay is already active and the due date is close, check the portal before making a manual payment.

Water system

Fairfield Water System Facts Users Actually Ask About

Fairfield Municipal Utility serves customers through a large water infrastructure system, not just a billing counter. These facts help users understand where water comes from and why water-quality reports matter.

System item Official detail Why users care
Source water Upper Putah Creek / Lake Berryessa and Northern Sacramento River Valley / Lake Oroville. Explains regional supply sources behind Fairfield tap water.
Treatment plants Waterman Water Treatment Plant and North Bay Regional Water Treatment Plant. Shows why water is treated before distribution.
Treatment capacity Combined maximum capacity of 70 million gallons per day. Shows scale of the system.
Storage Twelve reservoir storage facilities with about 78 million gallons of treated water storage capacity. Explains system reliability and pressure support.
Distribution Over 375 miles of underground piping and 15 pump station facilities. Helps explain leaks, maintenance and pressure zones.
Connections More than 33,000 customer connections. The water meter is the interface between City system and customer account.
Customer insight: If a problem is inside your plumbing after the meter, it may be different from a City distribution issue. If water is leaking in the street, near a meter, or across public space, report it quickly.

Fairfield Water Conservation, High Bill Clues and Water Waste

Report leak MyFairfieldCA App or 707-428-7485 Water leaks are repaired on a priority basis.

High-bill trick: In MyFMU, compare your current bill to previous cycles. If usage spiked but household habits did not change, check irrigation timers, toilet flappers, running valves, meter-side leaks and outdoor watering before calling.
