Antioch water bill payment options
People searching for “Antioch water bill pay,” “City of Antioch utility bill online,” or “Antioch water payment phone number” usually need the official payment route first, especially when the account is close to due or already in warning status.
The City of Antioch offers several official payment methods. Online and phone payment are the fastest options for most customers. AutoDraft is better if you want the bill pulled automatically from a checking account every month.
1) Pay online
Use Antioch’s official Municipal Online Services website to view account detail, transaction history, address, consumption information, and make a payment.
Best for: one-time payments, online account review, and stopping water service online.
2) Pay by phone
The City lists a 24/7 automated payment number for utility bill payments.
Phone: (866) 301-8999
3) AutoDraft from checking account
Antioch lets customers submit an AutoDraft authorization form to have the monthly water bill paid automatically from a checking account.
Best for: avoiding missed due dates and manual monthly payments.
4) In person / drop box / mail
You can pay in person at City Hall, use the drive-up drop box, or mail your payment to the city’s utility billing lockbox.
Address: Antioch City Hall, 200 H Street, Antioch, CA 94509
How to pay Antioch water bill online step by step
Use these steps if you want to pay online and avoid payment delays or wrong portals. This is especially important if your account is close to its due date.
Open the official Antioch payment portal
Go directly to the official City of Antioch utility billing payment system at antiochca.municipalonlinepayments.com/antiochca.
Review your account information
The portal lets you view account detail, transaction history, address, account information, and water consumption information before you pay.
Choose your payment method
The City states it currently accepts Visa, MasterCard, and Discover payments from the water account holder only through the online system.
Submit before the deadline
If your account is still in normal status, online payment is fine. But if you already have a Final or Disconnection Notice, do not wait until after that date expires.
Save proof of payment
After submitting, save the confirmation number or receipt and keep it until the payment appears correctly on your account.
Use customer service if the account is already in warning status
If your disconnection deadline has already passed, the city says website payments will not avoid disconnect, reactivate, or reconnect service. In that case, call customer service or pay in person directly with guaranteed funds.
Do not rely on online payment after the disconnection deadline: Antioch’s suspended-account policy says online/electronic payments made via the website or a financial institution will not avoid disconnect, reactivate, or reconnect water service after the extension/disconnection notice due date has passed.
Antioch water bill fees, due-date rules, and suspended account charges
This is the part most customers need when a bill is close to due. The rules change once an account moves into suspended or disconnection status, so use the table below before deciding how to pay.
| Billing item | Official detail | What you should do |
|---|---|---|
| Late fee | 5% on payments not received by the due date | Pay before the due date shown on your bill to avoid the extra charge. |
| Returned payment fee | $51.00 | Make sure funds are available before paying. A returned payment can also trigger immediate disconnection risk. |
| Suspended account processing service charge | $29 | If the Extension/Disconnection Notice due date is missed, this charge is added and the account is scheduled for disconnection. |
| Disconnection service charge | $108 | If service is disconnected, expect this extra charge in addition to the unpaid balance. |
| Minimum deposit | $300 may be required | Be prepared for this if service has been disconnected or if account history triggers deposit requirements. |
| Same-day service fee | $158 | Avoid last-minute start/restore requests when possible because same-day service costs more. |
| Tamper fee | Minimum $250 | Do not tamper with the meter or try to restore service yourself. |
| Water setup fee | $36 | This applies when starting service and is separate from any required deposit. |
How Antioch AutoDraft works
Antioch offers AutoDraft so your monthly water bill can be automatically paid from your checking account. This is a practical option if you do not want to remember the due date every month.
The city says you can submit the AutoDraft Authorization Form in person or by email to customer service. This is different from making a one-time online card payment because AutoDraft is built for monthly checking-account payments.
- Download the official AutoDraft Authorization Form from Antioch’s Water Services page.
- Complete the form with the water account number and checking-account information.
- Submit it in person or email it to service@antiochca.gov.
- Keep paying manually until customer service confirms AutoDraft is active.
- Call (925) 779-7060 if you want to confirm setup status.
Helpful tip: If your account is near disconnection, do not assume an AutoDraft form or delayed electronic payment will protect service. Call customer service directly and follow the suspended-account payment instructions.
Pay by phone, mail, in person, or drop box
If online payment is not convenient, Antioch still provides several official payment methods. Choose based on how close the bill is to the due date and whether the account is already on a Final or Disconnection Notice.

What to do if your Antioch water bill is late or service is at risk
If your account is in final notice or already suspended, paying the same way you normally do may not be enough. Antioch’s policy changes after the extension/disconnection deadline passes.
- Check whether your account is still in regular status or already on a Final/Disconnection Notice.
- If you are still before the deadline, pay online or by phone immediately.
- If the deadline has already passed, call (925) 779-7060 or go in person.
- After the deadline passes, Antioch says payment must be made by the water account holder only, in guaranteed funds only, and no checks are accepted.
- If service is already off, make sure all faucets and irrigation shut-off valves are off before restoration.
