Residents of the Cinco Ranch municipal utility district in Katy, Texas will need to update their payment information as the district transitions to a new billing software system and online customer portal. This includes receiving new account numbers, re-enrolling in auto pay, and using a new mailing address for check payments. The new online portal offers multiple payment options like eCheck, debit, and credit card.

Why it matters

The change in billing systems and payment methods is important for Cinco Ranch MUD residents to be aware of to ensure their water service continues without interruption. Updating payment information is required, and failure to do so could lead to late fees or service disruptions.

The details

Residents affected by the change will receive new account numbers that must be used for all future payments. Those enrolled in auto pay must log in and re-enroll to continue automatic payments, and may need to use a "make a one-time payment" option to cover their current balance before recurring payments resume. The payment mailing address has also changed to P.O. Box 3264, Dept. 10623, Houston, TX 77253-3264. The new online customer portal allows residents to view and pay bills using various electronic payment methods.

• Residents should watch for instructions on their water bills this month (February 2026) about the upcoming changes.

What’s next

Residents must update their payment information and re-enroll in auto pay by the end of February 2026 to avoid any disruptions to their water service.
