How to pay Fairfield water bill online step by step
If this is your first time paying through the current system, begin from the City of Fairfield official water/sewer payment page or the MyFMU portal. This helps avoid old saved bookmarks and unrelated third-party payment pages.
Open the official Fairfield water/sewer payment page
Go to the City of Fairfield Water/Sewer Bill Payment page or open the MyFMU portal directly at utilities.fairfield.ca.gov.
Create or access your MyFMU account
If you are a new customer, wait until your service is established and you receive your account number. Then use that information to create your online account.
Enter your account details carefully
Use the account number and customer details exactly as shown on your water/sewer bill. If the portal cannot find your account, contact Utility Billing before trying multiple random entries.
Review balance, usage, and payment amount
MyFMU allows customers to view bills, payment history, transaction history, and water consumption data. Confirm the account and service address before paying.
Submit your payment
Choose the payment method shown in the portal and follow the on-screen prompts. Check for any processing notice or confirmation screen before closing the page.
Save your receipt or confirmation
After payment, save the confirmation number, screenshot, or email receipt. Keep it until the payment appears correctly in your MyFMU account.
Old bookmark warning: Fairfield transitioned to the MyFMU by SilverBlaze utility portal. If your saved payment link does not work or looks different from the current City portal, start again from the official Fairfield website or the current MyFMU portal.
