Houston Water Department's online payment system lets you pay from your computer or phone without visiting an office or mailing a check
The City of Houston's Public Utilities Department runs the water system and accepts online payments through their official website. You can pay a single bill, set up a one-time payment, or arrange automatic monthly withdrawals from your bank account. The system accepts payments from anywhere with internet access, and most payments post to your account within one business day.
You will need your account number (printed on your bill) and a valid payment method — a bank account for electronic transfer, or a debit or credit card. The city charges a fee for credit and debit card payments but not for electronic bank transfers.
Key Takeaways
- Pay online through the City of Houston Public Utilities website using your account number and either a bank account or debit/credit card.
- Electronic bank transfers have no fee, but credit and debit card payments include a processing fee set by the payment processor.
- One-time payments and automatic monthly payments are both available through the same online system.
- Payments made before 5 p.m. Central Time typically post the same business day; payments after that post the next business day.
Finding your account number and bill information
Your account number appears in the top right corner of your water bill, usually printed as a series of numbers starting with a digit or letter. If you cannot find a printed bill, you can look up your account through the Houston Public Utilities website by entering your service address. The website will show your current balance, due date, and payment history.
If you have never set up an online account before, you will create a login using your email address and a password you choose. This account lets you view bills, set up autopay, and see payment confirmation numbers after each transaction.
Steps to make a one-time payment
Go to the City of Houston Public Utilities payment portal and sign in with your email and password. If you do not have an account yet, select "Create Account" and follow the prompts to register your service address and account number.
Once logged in, select "Make a Payment" or "Pay Now." Enter the amount you want to pay — you can pay the full balance, a partial amount, or a specific dollar figure. Choose your payment method: electronic bank transfer (no fee) or debit/credit card (fee applies). If you choose bank transfer, provide your routing number and account number. If you choose a card, enter the card number, expiration date, and security code.
Review the payment details, including the amount and any fees, then confirm the transaction. You will receive a confirmation number when ready. Save or print this number for your records. The payment will post to your account within one business day.
Setting up automatic monthly payments
Automatic payments withdraw money from your bank account or card on a date you choose each month, usually around your bill's due date. This option prevents late payments and removes the need to log in each month.
From your online account, select "Autopay" or "Automatic Payments" and choose the payment method and amount. You can set it to pay a fixed dollar amount each month or to pay whatever your current bill balance is. Select the day of the month you want the payment to occur — most people choose the due date shown on their bill. Confirm the setup, and the system will begin withdrawing on the date you selected in the following billing cycle.
You can change or cancel autopay at any time by logging back into your account and editing the autopay settings. There is no penalty for stopping automatic payments.
Payment methods and fees
| Payment Method | Fee | Processing Time |
|---|---|---|
| Electronic bank transfer (ACH) | None | Same or next business day |
| Debit card | Varies by processor, typically $2–$5 | Same or next business day |
| Credit card | Varies by processor, typically $2–$5 | Same or next business day |
Electronic bank transfer is the least expensive option because the city does not charge a fee for ACH transfers. The payment processor charges a fee for debit and credit card transactions; this fee is shown before you confirm the payment, so you know the total cost before completing the transaction.
Payments submitted before 5 p.m. Central Time on a business day post the same day. Payments submitted after 5 p.m. or on weekends and holidays post the next business day. If your bill is due on a weekend or holiday, the city typically does not charge a late fee if your payment posts on the next business day.
What to do if you cannot access the online system
If the website is down or you cannot create an account, you can pay by phone by calling the Houston Public Utilities customer service line. The phone number is listed on your water bill. Phone payments may include a higher fee than online payments.
You can also pay in person at a Houston Public Utilities office during business hours. Locations and hours are listed on the city website. In-person payments are usually processed when ready, but you will need to bring your account number or bill.
Mailed payments should be sent to the address on your bill. Mail payments take longer to post — typically 7 to 10 business days — so send them well before your due date to avoid late fees.
Understanding payment confirmation and receipts
After you complete an online payment, the system displays a confirmation number on your screen. This number proves the payment was submitted. Write down or screenshot this number for your records.
You will also receive an email confirmation to the address associated with your account. Check your spam folder if you do not see it within a few minutes. The email includes the confirmation number, payment amount, and the date the payment is expected to post.
Log into your account a day or two after payment to confirm the money has posted to your balance. Your account will show the payment in your transaction history with the date it was received.
Frequently Asked Questions
Can I pay someone else's Houston water bill online?
You can pay online only if you have the account number and can log into that account. If you want to pay a bill for someone else, contact Houston Public Utilities customer service to ask about authorized user options or third-party payment arrangements.
What happens if I pay late?
Late fees are added to your account if payment is not received by the due date shown on your bill. The amount of the late fee is listed in your service agreement. If you pay online after the due date, the payment still posts, but the late fee remains on your account unless the city waives it. Contact customer service if you believe the late fee was applied in error.
Can I set up autopay and still make manual payments?
Yes. You can have autopay active and also make additional one-time payments whenever you want. The system will not double-charge you — if you make a manual payment before autopay withdraws, you can adjust or pause autopay for that month to avoid overpaying.
Is my bank information safe when I pay online?
The Houston Public Utilities website uses encryption to protect your financial information during transmission. However, the city is not responsible for security breaches on your own device. Use a find, private internet connection when entering bank or card details, and never share your login credentials with anyone.
How do I get a receipt for my water bill payment?
Your confirmation email serves as a receipt. You can also print or screenshot the confirmation page that appears after you submit payment. Log into your account anytime to view your payment history, which shows all past payments with dates and amounts.
