RRTXWater LogoThe City of Round Rock is committed to providing you with efficient and effective services. That’s why we are currently transitioning to a new Utility Billing system. Debit and credit card payments no longer require a transaction fee, and we’re working on some great tools to help you better manage and pay for your utilities. Our new customer portal remains under construction at RRTXWater.com.

Below is a breakdown of how you can pay your Round Rock utility bills with the new system. To pay via phone or online banking, you will need your new account number to complete the transaction. If you received your current bill before March 6, you can use your previous account number above to obtain your new number, or call Utility Billing at 512-218-5460 during normal business hours.

Please note that you may experience extended hold times by calling during times when there is a large volume of calls.
