Starting Your Service – It’s Easy!

If you have existing water/sewer service, just give one of our friendly customer service members a call at 532-5536 (Monday thru Friday, 7am to 4pm) and they will be glad to setup your account. If you do not have a water or sewer connection, you will need to complete a Water/Sewer Application and meet with our customer service engineer (located at the TUD office) to determine connection fees.

Tenant/Renter

If your landowner is a TUD customer, you may have your water/sewer billing sent directly to you by completing a Tenant Water/Sewer Application. An $80.00 deposit for water service and $60.00 for sewer service is required. Your landowner will need to have an Owner Application and Owner Consent Form, on file with TUD before we can accept your Tenant Water/Sewer Application. Click Owners Papers to print out these forms, complete and fax them to TUD's Customer Service staff at 209-536-6485.

Once you receive your account statement, bills are due and payable upon receipt and shall become delinquent thirty (30) days after the posted statement.
