Dallas Water Utilities accepts payments online, by phone, by mail, and in person at drop boxes

Dallas Water Utilities (DWU) operates the water and wastewater system for the city of Dallas. You can pay your bill through several channels, each with different processing times and requirements. The fastest method is online through the DWU website or mobile app, which processes when ready. Phone and mail payments take longer — typically 5 to 7 business days to post to your account.

Your bill arrives monthly and shows your account number, the amount due, and the due date. You will need this information to pay by any method. If you have lost your bill, you can look up your account on the DWU website using your service address or account number.

Key Takeaways

  • Online payment through the DWU website or app posts to your account the same day and carries no fee.
  • Phone payments (214-671-4000) process in 5 to 7 business days and may carry a convenience fee depending on your payment method.
  • Mail payments should be sent to the address on your bill and take 7 to 10 days to post, so plan ahead to avoid late fees.
  • In-person drop boxes are located at DWU payment centers and some retail locations, and payments are processed within one business day.
  • Late fees begin 16 days after the due date, and service can be disconnected if your account reaches 60 days past due.

Paying online through the DWU website or app

The DWU website (dallaswatertx.gov) has a "Pay My Bill" section where you can log in with your account number and service address, or create an online account. Once logged in, you can view your current balance, payment history, and due date. You enter your payment amount and choose your payment method — bank account (ACH), debit card, or credit card.

Bank account payments are free and post the same day. Debit and credit card payments carry a convenience fee, typically 2.5% of the amount paid, charged by the payment processor. The fee is added to your payment total, not deducted from it. After you submit, you receive a confirmation number when ready.

The DWU mobile app (available on iOS and Android) offers the same payment options as the website. Payments made before 5 p.m. Central Time on a business day post the same day. Payments made after 5 p.m. or on weekends post the next business day.

Paying by phone

You can pay by phone by calling DWU customer service at 214-671-4000. Have your account number and payment method ready. The automated system will walk you through the payment process, or you can speak to a representative during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time).

Phone payments are processed as ACH (bank account) or card payments. ACH payments are free; card payments carry a convenience fee. The payment will not post when ready — it typically takes 5 to 7 business days. If you are close to your due date, online payment is faster.

Paying by mail

You can mail a check or money order to the address printed on your bill. Include your account number on the check. Mail payments take 7 to 10 days to post, so send your payment at least 10 days before the due date to avoid a late fee.

Do not send cash by mail. If your payment does not post within 10 business days, contact DWU to confirm it was received. Keep a copy of your check or money order number for your records.

Paying in person at DWU drop boxes and payment centers

DWU operates payment drop boxes and customer service centers where you can pay in person. The main payment center is located at 1500 Marilla Street, Dallas, TX 75201. Additional drop boxes are located at various DWU facilities and some retail locations throughout Dallas.

You can pay by check, money order, or cash at in-person locations. Payments are processed within one business day. Hours vary by location — the main center is open Monday through Friday, 8 a.m. to 5 p.m. Central Time. Check the DWU website for the complete list of drop box locations and hours.

Understanding late fees and service disconnection

Your bill is due on the date shown on your statement. If payment is not received by that date, a late fee is added to your account 16 days after the due date. The late fee is typically 5% of the amount due or a minimum amount set by DWU, whichever is greater.

If your account reaches 60 days past due, DWU may disconnect your water service. A disconnection notice is sent before service is shut off, giving you time to pay or contact DWU to discuss your options. Once disconnected, a reconnection fee applies in addition to the balance owed. If you are having trouble paying, contact DWU at 214-671-4000 to ask about payment arrangements.

Setting up automatic payments

You can set up automatic monthly payments through the DWU website or by phone. Automatic payments deduct your bill amount from your bank account on a date you choose, typically around your due date. This prevents missed payments and late fees.

To set up automatic payments online, log into your account, go to the payment section, and select the automatic payment option. You will need your bank account information. You can change or cancel automatic payments at any time through your online account or by calling 214-671-4000.
