Tuoco Pay My Bill

TUD Online Payment System

Important Message from TUD

The Tuolumne Utilities District has recently updated to a new improved customer billing software system.

Should you need to make a payment or have questions concerning your account, please call our Customer Service Department at (209) 532-5536.  The District also accepts payments at our TUD office at 18885 Nugget Blvd., Sonora from 7am to 4pm, Monday through Friday, and we also have a drop box for payments located in the parking lot.


As part of the new billing software upgrade, all TUD customers will be assigned a new TUD account number. If you have your current TUD account setup with a financial institution for payment, you will need to update this information with your new TUD account number.

You can set up your new TUD account for auto pay and to receive email paperless statements. All TUD customers will now be billed bi-monthly, every two months. If you do not yet have a new billing statement, please call our Customer Service staff at 209-532-5536, Monday through Friday between 7am to 4pm to receive your new account information. Or send an email to customersvc@tudwater.com.

Find out how to read your new billing statement by looking at the example below.
