Houston Water and Wastewater Utilities offers three main ways to pay online: through your account on the city website, by phone, or through an automatic payment plan
The fastest route is logging into your account at houstontx.gov/water. You can pay a single bill there without setting up anything permanent, or you can arrange automatic payments so the amount comes out on a date you choose each month. You will need your account number, which appears on your paper bill or in any email notice from the city.
If you do not have an online account yet, you can create one in a few minutes using your service address and account number. Once you are logged in, you can view your current balance, see your payment history, and set up autopay from a checking or savings account.
The other options — paying by phone or setting up automatic withdrawal — work the same way but do not let you see your bill details first. Most people find the website easiest because you can check what you owe before you commit to payment.
Key Takeaways
- You can pay online at houstontx.gov/water using your account number from your bill, with no account setup required for a one-time payment.
- Automatic payments come out on a date you choose each month and require a checking or savings account, but you can cancel anytime.
- Paying by phone through the city's automated system is available 24/7, but you cannot review your bill before payment goes through.
- Late fees and service interruption begin after your bill is 30 days overdue, so setting up autopay prevents accidental missed payments.
Setting up a one-time online payment
Go to houstontx.gov/water and look for the "Pay My Bill" button on the homepage. Click it and enter your account number (a 10-digit number on your bill) and your service address. The system will pull up what you owe.
You can then choose to pay the full amount or a partial payment. Enter your checking or savings account information, and the payment will process immediately. You will get a confirmation number on screen and by email. Most payments show up in the city's system within one business day.
If you do not have your account number handy, you can search by your service address instead, though this takes a few extra seconds. Keep your confirmation number in case you need to dispute the payment later.
Creating an online account and setting up autopay
Creating an account takes about five minutes and lets you see your bill history, track usage, and manage payments all in one place. Go to houstontx.gov/water, select "Create Account," and enter your service address and account number. You will set a username and password.
Once you are logged in, go to "Billing" and select "Enroll in AutoPay." Choose the date each month when you want the payment to come out — the 1st, 15th, or any other day that works for you. The city will withdraw the full amount due from your checking or savings account on that date.
You can change or cancel autopay anytime by logging back in. If your bill amount changes (which it does seasonally for most households), the new amount will be withdrawn on your chosen date. This prevents late fees because the payment goes out automatically even if you forget.
Paying by phone
You can call the Houston Water automated payment line at 713-207-2700 to pay by phone 24 hours a day, 7 days a week. Have your account number and a checking or savings account ready. The system will ask for your account number, the amount you want to pay, and your bank details.
Payments made by phone process the same way as online payments — usually within one business day. You will hear a confirmation number at the end of the call. Write it down or take a screenshot if you are on a mobile phone.
The downside of paying by phone is that you cannot see your bill details before you commit to the payment amount. If you are unsure what you owe, use the website instead so you can review first.
What to do if you cannot pay the full amount
If you owe money but cannot pay it all at once, you have a few options. You can make a partial payment online or by phone — the city will accept whatever amount you can pay, and you will owe the rest on your next bill. Partial payments do not stop late fees from starting, but they do show the city you are working on the debt.
If you are behind on payments and worried about service being shut off, contact the Houston Water Customer Service line at 713-207-2700 during business hours (Monday through Friday, 7 a.m. to 6 p.m.) to ask about a payment plan. The city can sometimes arrange a schedule where you pay part of what you owe now and the rest over the next few months. This stops the shutoff clock while you catch up.
Service interruption begins 30 days after your bill is due. If you are close to that date, calling to set up a plan is faster than waiting — the city will not shut you off while a plan is in place.
Checking your payment history and account details
Once you have an online account, you can log in anytime to see what you have paid and when. This is useful if you are disputing a charge or trying to remember whether a payment went through. Your account shows the date the payment was received, the amount, and the confirmation number.
You can also see your usage history month by month, which helps you understand why your bill went up or down. The website shows how much water you used and what you were charged for it. If a bill looks wrong, you can contact customer service with your account number and the specific month in question.
Common mistakes to avoid when paying online
The most common mistake is entering the wrong account number. If you type it incorrectly, the payment may go to someone else's account or fail entirely. Double-check the number on your bill before you submit payment. If a payment fails, you will see an error message right away — do not assume it went through.
Another mistake is setting up autopay and forgetting about it, then being surprised by the withdrawal. Mark your calendar for your autopay date so you know when to expect the charge. If your balance drops below what you usually owe (because you used less water that month), the city will still withdraw your full autopay amount, so you may end up with a credit on your account.
Do not pay through a third-party bill payment service unless you are certain it is legitimate. The city's official website is houstontx.gov/water. Scam sites sometimes appear in search results and charge fees or steal account information. Stick with the city's own system or call the official phone number.
Frequently Asked Questions
How long does it take for an online payment to show up on my account?
Most online and phone payments show up in the city's system within one business day. If you pay on a Friday evening, it may not appear until Monday. You will get a confirmation number immediately when you pay, so you have proof the payment was sent even if it has not posted yet.
Can I change my autopay date if I get paid on a different day of the month?
Yes. Log into your account, go to "Billing," select "AutoPay," and choose a new date. The change takes effect on your next payment cycle. If you need to change it before your next scheduled payment, call customer service at 713-207-2700 to make sure the change goes through in time.
What happens if I set up autopay but my account does not have enough money on the payment date?
The payment will fail and you will be notified by email. You will then owe a late fee in addition to your bill amount. If this happens, log back in and make a manual payment as soon as possible, or call customer service to discuss a payment plan before the 30-day late period begins.
Is there a fee for paying online or by phone?
No. The city does not charge a fee for paying through their official website or phone line. If a third-party service charges you a fee to pay your water bill, that is not an official city payment method and you should avoid it.
Can I pay someone else's Houston water bill online?
You can pay if you have the account number and service address, but the account holder should set up a payment arrangement with you first. The city does not verify who is making the payment, only that the account number and amount are correct. If you are paying a family member's bill regularly, they can add you as an authorized user on their account so you can manage payments directly.
