How to Start Fullerton Water Service
To establish water service, call Utility Services at 714-738-6890. The City says customer service representatives can take your information over the phone, and trash services are included for residential and multi-family accounts.
| Requirement | Official detail | Practical tip |
|---|---|---|
| Phone | 714-738-6890 | Call Utility Services, not the leak line. |

How to Stop Fullerton Water Service
To terminate water service, Fullerton says customers must call 714-738-6890. Email requests are not accepted for termination.
Call at least one business day ahead
Provide the desired termination date, forwarding address and phone number.
Do not call before escrow closes
If you are selling the property, the City says not to call until escrow has closed.
Expect a prorated final bill
Fullerton says the final bill is prepared 2-3 weeks after the termination date and sent to your forwarding address.
Fullerton Water AutoPay: What to Know Before Enrolling
Fullerton’s AutoPay program drafts the amount due from your bank account on the bill due date. The City describes AutoPay as a free service set up through a checking account.
AutoPay helps if…
You pay every cycle, want fewer missed bills and keep a stable checking account balance.
Review first if…
You often dispute usage, had a recent leak, or need to confirm the bill amount before money is drafted.
Complete the official AutoPay application
Use the AutoPay route linked from the City’s payment page.
Attach a voided check
The City says the completed application should be mailed or brought to City Hall with a voided check.
Still check usage before the due date
AutoPay prevents missed payment problems, but it will not warn you by itself if irrigation or a leak has raised usage.
