How to Pay Your Houston Water Bill Online and by Mail

Where to pay your Houston water bill

The City of Houston's Public Utilities charges for water, wastewater, and stormwater through a single monthly bill. You can pay online through the city's official website, by phone, by mail, or in person at payment centers. The fastest and most common method is online payment through the city's bill pay portal, which processes when ready and requires only your account number and a valid payment method.

If you prefer not to pay online, you can call the city's customer service line to pay by phone with a debit or credit card. Payments made by phone are processed the same day if you call before the cutoff time, which varies by payment processor. Mail payments take 7 to 10 business days to reach the city, so send them well before your due date to avoid late fees.

In-person payment at a Houston Public Utilities office or authorized payment center is also an option. The main office is located downtown, but the city operates several satellite locations across Houston. You can pay in cash, check, or card at these locations during business hours.

Key Takeaways

• Online payment through the city's website is the fastest method and shows as received when ready, with no processing delay.
• Phone payments with a debit or credit card process the same day if you call before the cutoff time, which the payment processor will tell you.
• Mail payments take 7 to 10 business days, so you should mail your check at least two weeks before the due date to avoid a late payment.
• The city charges a late fee if payment is not received by the due date shown on your bill, regardless of when you sent it.
• You can set up automatic monthly payments through the online portal so you never have to remember to pay manually.

Paying online through Houston Public Utilities

To pay online, go to the City of Houston's Public Utilities website and log into your account or create one if you do not have one yet. You will need your account number, which appears on your bill, and an email address. Once logged in, select the option to make a payment and enter the amount you want to pay.

The portal accepts debit cards, credit cards, and bank account transfers. If you use a debit or credit card, the payment posts to your account when ready. If you pay by bank transfer (ACH), the payment may take one to two business days to clear. There is no fee for paying by bank transfer, but the city charges a convenience fee if you pay by debit or credit card—this fee varies and will be shown before you confirm the payment.

After you submit payment online, you will receive a confirmation number. Save this number in case you need to dispute the payment or verify it was received. The city also sends an email confirmation to the address on file.

Setting up automatic payments

If you want to avoid paying your bill manually each month, you can set up automatic payments through the online portal. Automatic payments deduct money from your bank account on a date you choose, usually a few days before the due date. This method has no convenience fee and ensures you never miss a payment important date.

To enroll, log into your account online and look for the autopay or recurring payment option. You will need to provide your bank account number and routing number. You can change the payment amount or pause autopay at any time through the same portal. If your bill amount changes significantly, you may want to adjust your automatic payment to match.

Mailing a check or money order

If you prefer to pay by mail, write your account number on the check or money order and send it to the address shown on your bill. The city's mailing address for payments is typically a lockbox operated by a payment processor, not the main office. Always use the address printed on your bill, as it may change.

Mail payments take 7 to 10 business days to arrive and be processed. The city considers your payment on time if it is postmarked by the due date, not if it arrives by the due date. However, to be safe, mail your payment at least two weeks before the due date. If you are paying close to the important date, use online or phone payment instead to avoid a late fee.

Include only the payment stub from your bill if you have one—do not send the entire bill. If you do not have a stub, write your account number clearly on the check so the payment is applied to the correct account.

Paying by phone

To pay by phone, call the Houston Public Utilities customer service number listed on your bill. Have your account number and a debit or credit card ready. The automated system will walk you through the payment process, or you can speak to a representative if you prefer. Phone payments are processed the same day if you call before the cutoff time, which the system will tell you when you call.

The city charges a convenience fee for phone payments made by card, similar to the online card payment fee. There is no fee if you pay by bank account transfer over the phone. Keep your confirmation number from the phone payment for your records.

What to do if your payment is late

If your payment is not received by the due date on your bill, the city will charge a late fee. The amount of the late fee is a percentage of your bill and is shown in your account. Late payments also affect your credit report if they are reported to credit bureaus, though the city typically reports only after 30 days past due.

If you cannot pay by the due date, contact the city's customer service line to discuss your options. The city may offer a payment plan or temporary relief depending on your situation. Do not ignore a late bill—the city can shut off your water service if your account becomes significantly past due, usually after 60 to 90 days without payment.
