Late payment & disconnection
What Happens When a Cobb County Water Bill Is Past Due?
Cobb Water’s current delinquency guidance states that if the current balance remains unpaid 10 days after the bill due date, the account becomes delinquent and a $10 late fee is assessed.
How service restoration works
-
1
Pay the full past-due balance
Partial payment does not satisfy the County’s published restoration requirement.
-
2
Pay the $50 processing fee
A deposit can also apply when required for the account.
-
3
Pay before 3 p.m. for same-day restoration
Payments after 3 p.m. are scheduled for restoration the next business day under current guidance.
-
4
No call is normally required after full online payment
Cobb says restore orders are generated automatically after the required full balance and processing fee are received.
Cobb’s current delinquency policy states that after two returned payments, the account is required to pay by cash or money order for one year.
Need more time?
Cobb Water Payment Plan Help
Cobb County directs customers who need to set up a payment plan to contact Water System Customer Service.
If you know you cannot pay the full balance, contact Customer Service before the account reaches the disconnection stage and ask what arrangements are currently available.
Unexpected high bill
Apply for a Cobb County Water Leak Credit
Cobb Water provides a partial leak credit for eligible repaired leaks. It is designed to reduce part of the unusual water/sewer cost—not erase the full bill.
Prepare these items
- Service address and account number
- Brief explanation of the leak
- Plumber’s repair receipt or parts receipt
- Repair explanation letter when a traditional receipt is unavailable
- Pool volume for qualifying pool-leak claims
Cobb Water directs customers to log into the Customer Self-Service Portal and submit the leak-adjustment request online.
Before disputing usage
High Cobb Water Bill? Check the Meter First
Check the 13-month graph
A sudden usage spike can indicate a leak if household water habits have not changed.
Compare your meter
The current meter reading should be equal to or greater than the end reading on the latest bill.
Watch the leak indicator
If the arrow or triangle moves while all water use is off, water may still be flowing somewhere.
Use a one-hour test
Turn off all water, record the meter, wait an hour without using water and check it again.
A leak before the meter should not normally affect billed consumption and is generally a Cobb Water repair responsibility.
Leaks after the meter are generally the property owner’s responsibility.
Severe utility problems
