Dallas Water Utilities payment options and where to send your money
Dallas Water Utilities (DWU) lets you pay your bill online through their website, by phone, by mail, or in person at payment centers. The online portal at dwu.org is the fastest route — you can pay immediately with a bank account or debit card, and the payment posts within one business day. If you prefer not to use the internet, you can call 214-671-2700 during business hours, mail a check to the address on your bill, or visit a payment location in person.
Your bill arrives monthly and shows the amount due, the due date, and all the payment methods available to you. The due date is typically 20 days after the bill date. If you pay after the due date, DWU charges a late fee — currently 1.5% of the unpaid balance, with a minimum of $5. Knowing your due date and choosing a payment method that works for your schedule helps you avoid these charges.
Key Takeaways
- You can pay online at dwu.org with a bank account or debit card, and the payment posts within one business day.
- Phone payments go through the automated system at 214-671-2700 or with a representative during business hours.
- Mailed checks should be sent to the address printed on your bill, and you should mail them at least one week before the due date to avoid late fees.
- Late payments incur a 1.5% fee with a $5 minimum, so setting up autopay or a calendar reminder can protect you from unexpected charges.
- If your bill is unusually high, you can request a meter reading or check for leaks before paying, since DWU allows disputes within a set timeframe.
Paying online through the DWU website
Go to dwu.org and look for the "Pay My Bill" button, usually on the homepage. You will need your account number, which appears on your bill, and either a bank account or debit card. Enter your account number, the amount you want to pay, and your payment method. The system will show you a confirmation screen before you submit — review it to make sure the amount and account are correct.
Online payments are processed immediately, but the money may take one business day to appear in your account as paid. If you are paying close to the due date, the online method is safer than mail because you get instant confirmation. DWU does not charge a fee for online payments made through their official website.
If you want the same payment to happen automatically every month, look for an autopay or recurring payment option on the same portal. You set it once, and DWU withdraws the amount on or near your due date. This removes the risk of forgetting to pay and triggering a late fee.
Paying by phone or through an automated system
Call 214-671-2700 to reach DWU's payment line. You can use the automated system 24 hours a day, 7 days a week, or speak to a representative during business hours (typically 8 a.m. to 5 p.m. Monday through Friday). Have your account number and a debit card or bank account ready. The automated system will walk you through the payment step by step and give you a confirmation number at the end.
Phone payments process the same way as online payments — immediately, with the money showing as paid within one business day. There is no fee for paying by phone through DWU's official line. If you call a third-party payment processor instead, they may charge a convenience fee, so always use the number on your bill or the official DWU website to avoid extra charges.
Mailing a check or money order
Write your account number on the check or money order, and mail it to the address shown on your bill. DWU's mailing address changes based on which payment processing center handles your account, so always use the address printed on your statement rather than looking up a general office address. Include your bill stub if possible — it helps the payment post faster.
Mail your payment at least 7 to 10 days before the due date to account for postal delays. If you mail it closer to the due date and it arrives after the due date, DWU will charge a late fee even though you sent it on time. If you are cutting it close, use online or phone payment instead. Keep a copy of the check or the confirmation number from your bank for your records.
Paying in person at DWU payment centers
DWU operates payment centers where you can pay cash, check, or debit card in person. Locations are listed on dwu.org under "Payment Locations" or "Pay in Person." Hours vary by location, so check before you go. Bring your account number and your bill if you have it. Payment centers are useful if you prefer to handle money in person or if you do not have online or phone access.
In-person payments are posted the same day if you pay before the center closes. This is the fastest way to ensure your payment is recorded immediately, which matters if you are paying on or very close to the due date. Some payment centers may charge a small fee for certain payment methods, so ask before you pay.
What to do if your bill is higher than expected
Before you pay a bill that seems wrong, check for a water leak in your home. Look under sinks, around toilets, and in the basement or crawl space for dripping water or wet spots. A running toilet or a slow leak can add hundreds of gallons to your usage in a month. If you find a leak and fix it, your next bill should be lower. If you believe the leak was not your fault — for example, if it was in a shared building system — contact DWU to discuss the bill.
You can also request that DWU read your meter again to verify the amount. Call 214-671-2700 and ask for a meter reading verification. DWU will send someone to check the meter and confirm whether the reading on your bill is accurate. If the meter was misread, DWU will correct your bill. If the reading is correct but your usage is genuinely high, the meter is working as it should, and you will owe the amount shown.
DWU allows you to dispute a bill within a certain timeframe — usually 30 days from the bill date. If you think there is an error, contact them in writing or by phone before the due date to explain the issue. Paying the bill does not prevent you from disputing it later, but paying on time protects you from late fees while the dispute is being reviewed.
Setting up autopay to avoid missed payments
Autopay is the easiest way to make sure you never miss a due date. On the DWU website, select the autopay option and choose the amount you want to pay each month — you can pay the full bill or a fixed amount. Choose the date you want the payment to come out, ideally a few days before the due date. DWU will withdraw the money automatically on that date every month until you cancel.
Autopay works with a bank account (which usually has no fee) or a debit card (which may have a small fee depending on DWU's current policy). You can change or cancel autopay anytime through your online account. If your bill amount changes significantly — for example, if you move to a smaller home or fix a major leak — you can adjust your autopay amount or switch back to paying manually.
Frequently Asked Questions
What happens if I pay late?
DWU charges a late fee of 1.5% of the unpaid balance with a $5 minimum. If you are more than 30 days late, DWU may send a notice of intent to disconnect service. If you reach 45 days late, your water service can be shut off. Contact DWU immediately if you cannot pay on time to discuss payment plans or hardship programs.
Can I set up a payment plan if I cannot pay my full bill?
Yes. Call 214-671-2700 and explain your situation. DWU offers payment arrangements for customers who are behind or facing hardship. The terms depend on how much you owe and your circumstances, but a representative can work with you to create a plan that keeps your service active while you catch up.
Is there a fee for paying online?
No. DWU does not charge a fee when you pay through their official website at dwu.org or through their phone line at 214-671-2700. Third-party payment processors may charge convenience fees, so always use DWU's official channels to avoid extra charges.
How long does it take for a mailed payment to post?
Mailed payments typically take 7 to 10 business days to post to your account, depending on postal delivery and DWU's processing time. Mail your payment at least 10 days before the due date to be safe. If you are paying close to the due date, use online or phone payment instead.
What if I overpay my bill?
If you pay more than you owe, DWU will credit the extra amount to your next bill. You can also request a refund by contacting DWU directly. The refund process takes a few weeks, so most customers prefer to let the credit apply to the next month's bill.
