This guide is for Cobb County Water System customers who need to pay a bill, use QuickPay, create a Customer Self-Service account, update a bank bill-pay number, request a payment plan, start service, or apply for a leak adjustment.
Each step includes the official county link or phone number next to the action, so you can finish the task without hunting through multiple pages or trusting a random payment result.
Fast answer: Cobb County Water System customers can pay through QuickPay with the account number, or use the Customer Self-Service portal to manage bills, payments, consumption, water-service requests and leak-credit adjustments. The account number appears on the top right of the bill below the amount due and payment due date.
Past-due account? Cobb County says to pay the full past-due balance immediately. If you need a payment plan, contact ccwscustomerservice@cobbcounty.gov. If assistance is confirmed by a charitable organization, email that confirmation to the same address to help avoid service disconnection.

|---|---|---|---|
| Outdoor leak | Water may not enter the sewer system, which can affect how sewer credit is considered. | Repair invoice, date fixed, explanation and photos if available. | Apply for leak review |

How to Check for a Leak Before Calling Cobb Water
Cobb bills water use in 1,000-gallon increments and provides a 13-month consumption graph on monthly bills. Use that graph and the meter test before assuming the county made a billing error.
Check the consumption graph
Compare the current month to the same month last year, not only the previous month.
Understand water usageTurn off all water
Turn off indoor fixtures, outdoor spigots, irrigation, ice maker, washer and dishwasher.
Leak tipsWatch the meter indicator
Cobb says an arrow or triangle on the meter should not move when no water is being used.
Meter helpUse the one-hour test
Take a reading, wait one hour without using water, then take another reading. If it changed, you may have a sporadic leak.
