American Water's payment methods and where to send money

American Water operates in 14 states and serves roughly 3.4 million customers. The company accepts payments online through its website, by phone, by mail, and in person at authorized payment centers. Where you send your payment depends on which method you choose — online and phone payments go directly to American Water's processing system, while mailed checks go to a lockbox address that varies by state and region.

Your bill shows your account number and the mailing address for your specific service area. American Water does not charge a fee for online payments made through its website or for payments by phone. Third-party payment processors that offer bill pay services may charge their own fees, so check before you authorize a payment through an outside platform.

The company processes online payments submitted before 5 p.m. Eastern Time on a business day as same-day payments. Payments submitted after 5 p.m. or on weekends and holidays are processed the next business day. Mail payments typically take 7 to 10 business days to reach the lockbox and post to your account, so plan ahead if your bill is due soon.

Key Takeaways

  • American Water accepts online payments through its website at no charge, with same-day processing if submitted before 5 p.m. Eastern Time on a business day.
  • Phone payments are also free and can be made by calling the customer service number on your bill, which varies by state.
  • Mailed checks should be sent to the lockbox address printed on your bill, not to American Water's corporate office, and take 7 to 10 business days to post.
  • Payment centers operated by American Water or authorized third parties accept cash and check payments in person in some service areas.
  • Late fees and service disconnection begin after a set number of days past due, which varies by state and is shown on your bill.

Paying online through American Water's website

Go to the American Water website and select "Pay My Bill" or "Make a Payment." You will need your account number, which appears on your bill. The site asks for your zip code to route you to the correct regional system, since American Water operates separate billing systems for different states.

Enter your account number and either your service address or phone number associated with the account. The system displays your current balance and due date. You can pay the full amount due, the minimum payment, or a custom amount. American Water accepts bank account payments (ACH transfers) and debit or credit card payments online, though credit card payments may carry a processing fee depending on your card issuer.

After you enter payment details, the system shows a confirmation number. Write this down or take a screenshot — you will need it if you contact customer service about the payment. The payment is not final until you see the confirmation screen and receive a confirmation email.

Paying by phone

Call the customer service number on your bill. This number is specific to your state and region because American Water operates as separate companies in different areas. The automated system or a representative will ask for your account number and the amount you want to pay.

Phone payments are free when you pay from a bank account. Credit card payments by phone may carry a fee. The system provides a confirmation number at the end of the call. Payments made before 5 p.m. Eastern Time on a business day post the same day; calls after hours are processed the next business day.

Mailing a check or money order

Write your account number on the check or money order. The mailing address is printed on your bill — it is a lockbox address specific to your service area, not American Water's corporate headquarters. Sending payment to the wrong address delays posting to your account.

Mail your payment at least 10 business days before your due date to account for mail delivery time. The lockbox processes payments Monday through Friday, so payments mailed on Friday or over a weekend will not be processed until the following Monday. If your bill is due in fewer than 10 days, use online or phone payment instead.

Include only the check or money order and the payment stub from your bill if you have it. Do not include other documents or correspondence in the envelope, as the lockbox processes payments by machine and may not route other materials to the right department.

In-person payment at authorized locations

Some American Water service areas have payment centers or authorized retailers where you can pay in person with cash or check. These locations vary by state and region. Call the customer service number on your bill or check the American Water website to find payment centers near you.

Payment centers typically operate during business hours Monday through Friday and may have limited Saturday hours. Bring your account number and the amount you plan to pay. In-person payments are usually posted to your account within one business day.

What happens if you miss a payment

American Water sends a past-due notice when your bill remains unpaid after the due date. The number of days before late fees explore and before the company can disconnect service varies by state — check your bill or contact customer service for your state's rules.

If your account falls behind, you may be able to set up a payment plan. Contact American Water's customer service before your account is disconnected to discuss options. Some states require the company to offer payment arrangements to customers facing disconnection.

Setting up automatic payments

American Water allows you to set up automatic payments from your bank account through its website. Log into your account, go to the payment section, and select the option to enroll in automatic payments. You choose the payment amount and the date each month when the payment is withdrawn.

Automatic payments are free when drawn from a bank account. You can change or cancel automatic payments at any time through your online account. If you cancel, make sure to set up another payment method so your bill does not go unpaid.

Frequently Asked Questions

How long does it take for a payment to show up on my account?

Online and phone payments made before 5 p.m. Eastern Time on a business day post the same day. Mailed checks take 7 to 10 business days. In-person payments at authorized locations usually post within one business day. Check your online account or call customer service to confirm a payment has posted.

Can I pay my American Water bill through a third-party bill pay service?

Yes, many banks and bill pay platforms allow you to send payments to American Water. However, these services may charge their own fees and may take longer to process than paying directly through American Water's website. Check with your bank or service about fees and processing times before using a third-party platform.

What if I pay online but the payment doesn't go through?

If your payment is declined, the system will tell you why — usually an incorrect account number, expired card, or insufficient funds. Do not assume the payment went through if you did not see a confirmation number and confirmation screen. Try again with corrected information or use a different payment method.

Is there a fee to pay my bill online?

No, American Water does not charge a fee for online payments made through its website or for phone payments. Credit card payments may carry a fee from your card issuer. Third-party payment platforms may charge their own fees.

What should I do if I can't pay my full bill by the due date?

Contact American Water's customer service before your account goes past due. Some states require the company to offer payment plans or arrangements to customers who cannot pay in full. The sooner you contact them, the more options may be available to you.
