Start Water Service in Antioch: Homeowner and Renter Requirements

The City of Antioch has different documentation requirements for homeowners and tenants. Water service requests are generally scheduled for the next business day unless a later date is requested.

Homeowners: Open a Water Account

1. Open the city’s Water Services page.

2. Provide a valid government-issued photo ID.
3. Submit the full lease agreement, not just the signature page.
4. Arrange for the homeowner to complete the city’s online Verification of Tenancy form with the required identification.

The city currently publishes a $300 tenant water deposit, required at account creation, plus the $40 account setup fee charged to the first bill.

The city states that a third party may not submit the new-service application on behalf of the actual applicant. Property-owner or manager verification must follow the city’s designated process.

How Soon Can Water Be Connected?

Antioch generally schedules completed requests for the next business day. For eligible same-day service, the city lists an additional $193 fee.

The city also publishes a minimum $250 meter-tampering fee. Never attempt to activate service by operating or bypassing utility-owned meter equipment.

How to Stop Antioch Water Service When Moving

3. Enter the water account number and service address.
4. Provide the requested termination date.
5. Enter a forwarding mailing address for the final bill.

If you are closing a sale, confirm the service termination and final account balance before the transaction is completed.

For assistance, call 925-779-7060.

If Your Water Account Has Been Suspended

Antioch’s official payment portal gives an unusually important warning: after the final, disconnection or extension due date has passed, online payments and payments made through your financial institution are not sufficient to stop disconnection or restore service.

In this situation:

3. Confirm the required guaranteed-funds payment method. The city states that checks are not accepted for this situation.

The city states that restoration is normally scheduled for the next business day after requirements are satisfied. Same-day restoration requires an additional fee.

Understanding Your Antioch Water Bill and Rates

Antioch bills water service monthly. The city’s statement identifies the account, service address, billing period, water consumption and the charges applied to the property.

Your bill can include:

• Water consumption: Charges based on metered water use.
• Tiered rates: Different unit prices as usage moves into higher consumption blocks.
• Meter maintenance or fixed charges: Charges related to meter size and water system service.
• Sewer charges: Applicable wastewater charges listed separately from drinking-water consumption.
• Previous balance: Unpaid charges carried forward.
• Penalties or fees: Charges associated with late or returned payments where applicable.

The city provides a sample bill explaining where the account number, water usage comparison and individual charges appear.

How to Check Current 2026 Water Rates

Antioch uses a tiered water-rate structure. Exact rates depend on the approved tariff, meter classification, consumption and the effective billing period.

The amounts shown on an older sample bill should not be treated as the current October 2026 rate schedule.

For the charges applicable to your account, contact Water Services at 925-779-7060 or visit the official Water Services page for the city’s current billing resources.

High Water Bill or Suspected Leak in Antioch?

Unusually high water consumption can result from running toilets, leaking irrigation lines, damaged plumbing or changes in outdoor watering.

Antioch’s Water Services information explains that customers are generally responsible for water lost through leaks or fixtures on the property-owner side of the meter.

Check Your Water Usage

1. Find the current water consumption on your latest bill.
2. Compare it with the previous month and the same season last year.
3. Check toilets, faucets, hose connections and irrigation valves.
4. Look for unexplained wet ground or continuously running plumbing.
5. Use the city’s official meter-reading instructions if you need to confirm the displayed meter usage.
6. Contact Water Services if you believe the bill or meter information is incorrect.

Sign Up for EyeOnWater Leak Alerts

Antioch links to the EyeOnWater platform for water usage monitoring and leak alerts.

1. Open EyeOnWater from the city’s official Water Services page.
2. Follow the registration prompts to determine whether your utility account is supported.
3. Complete the required account verification.
4. Review the available water consumption information.
5. Configure leak or unusual-usage alerts if the feature is available for your meter.

EyeOnWater is a usage-monitoring service, not the city’s official bill-payment portal.

Can You Dispute an Antioch Water Bill?

Yes. Antioch Municipal Code Section 6-5.04.E provides a process for investigating disputed utility bills.

Customers must submit a written investigation request to the Finance Services Supervisor. The city’s rules explain that a disputed amount does not automatically justify withholding or delaying payment.

If the investigation is resolved in the customer’s favor, an applicable refund or account credit can be issued.

Contact service@antiochca.gov or 925-779-7060 to confirm how to submit a dispute and what evidence is needed.

Antioch, California vs. Antioch, Illinois Water Utilities

Searches for “Antioch Water Utility” can refer to two different municipal water systems. Their payment portals, phone numbers, billing schedules and service fees are not interchangeable.

Antioch, Illinois uses a separate water and sewer billing system. The village bills on a bi-monthly basis and currently uses BS&A Online for account access and payments.

Illinois customers: Use the Village of Antioch Water and Sewer Billing page. Do not submit an Illinois utility payment through the California portal.
