Westlake MUD 1’s water billing and payment system is getting an upgrade! Beginning December 5, residents will receive their first water bill through a new billing platform and customer portal managed by Inframark.
The payment processing transition will happen during the week of November 17. To ensure there’s no interruption in your service or payment history, please take a few minutes to review the key changes below.
New Account Number
Online Payment Updates
If you use auto pay or your bank’s online bill payment service, you will need to re-enroll and update the payment mailing address after the transition.
New Payment Address
If you’re mailing a check, please use the address printed on your new payment coupon.
If you’re using online bill-pay, please update the address to the following:
Westlake M.U.D. No. 1
P.O. Box 3264, Dept 10521
Houston, TX 77253-3264
An official billing insert with detailed instructions will accompany your December 5 water bill. Inframark will also send an email notification to customers about the transition process. Be on the lookout for an email from Inframark in your inbox (and check your spam folder just in case).
If you have any questions or need assistance during the transition, please contact Inframark Customer Service at customerservice@inframark.com or 832-467-1599. You can also visit www.inframark.com for more information.
Westlake MUD 1 appreciates your patience and cooperation as we move to a more convenient and user-friendly billing system.
