Pay or Log In: Exact Antioch Water Bill Steps

Open the official Antioch portal

Go to the City of Antioch Municipal Online Payments website and choose Antioch Water Utility Billing. The portal supports sign-in/register and may require JavaScript for full functionality.

Use your current bill to register or add an account

If you are registering for the first time or adding an account, have your most recent eBill or paper bill available. The portal says you will need your last payment amount.

Confirm account, service address and consumption

Before submitting payment, verify account detail, transaction history, service address and consumption information. This prevents paying the wrong account or missing a usage spike.

Check disconnection status before paying

If the final/disconnection/extension due date has passed, do not pay through the portal or your financial institution to restore service. Contact Customer Service and pay by the required guaranteed-funds route.

Save confirmation and call if timing matters

Save the confirmation number, payment amount, date/time, payment method and account number. Automated telephone or internet payments made to avoid disconnection must be made on or before the due date specified in the final or disconnection notice.
