Where and how to pay Cobb County water bills
Cobb County Department of Water System lets you pay by phone, online, by mail, or in person. The fastest method is online through their website at cobbcountywater.com, where you can pay immediately with a bank account or debit card. By phone, call 770-419-6000 during business hours and speak to a representative who can process payment over the phone. If you prefer mail, send a check or money order to the address printed on your bill — allow 7 to 10 days for it to arrive and post. In-person payment is also an option at their office, though you'll need to find current hours and location on their website first.
Online payment is the most common route because it's available 24/7 and shows as processed immediately. You'll need your account number, which appears on your bill, and either a checking account or debit card. Phone payment works the same day if you call before the payment deadline, but you may be charged a convenience fee depending on the payment method the representative offers you.

Setting up automatic payments
Automatic payment through Cobb County Water System removes the need to remember your due date each month. You can set this up online by logging into your account at cobbcountywater.com and selecting the autopay option, or by calling 770-419-6000 to have a representative set it up for you. The system will deduct your bill amount from your bank account on or shortly after your due date each month.
Autopay is useful if your bill amount stays roughly the same month to month, though it can vary seasonally — summer bills are typically higher due to outdoor watering. You can change or cancel autopay anytime through your online account or by calling the department. If you want to pause it for a month, you can do that without canceling the entire arrangement.
Understanding your bill and due date
Your Cobb County water bill shows your account number, the amount due, and the due date — usually 20 to 25 days from the bill date. The bill also breaks down charges by service: water usage, sewer service, stormwater fee, and any other applicable charges. Usage is measured in hundred-cubic-foot units (HCF), and your rate depends on how much water you used during the billing period.
The due date is the key date to watch. Payment received after that date triggers a late fee, which Cobb County adds to your next bill. If you're unsure of your due date, check the bill itself or log into your online account — both will show it clearly. Seasonal changes mean your bill may jump in summer months when irrigation use increases, so don't assume each month will be identical.
What happens if you miss a payment
A late fee is added to your account if payment arrives after the due date. The fee amount varies, so check your bill or contact the department at 770-419-6000 to learn the current late fee structure. If you miss multiple payments, Cobb County may suspend your water service, meaning your water will be shut off until the account is brought current.
If you're facing a hardship and cannot pay your bill on time, contact Cobb County Water System before the due date to discuss your options. Some utility departments offer payment plans or temporary deferrals for customers in financial difficulty, though availability depends on your situation. Calling ahead is far better than waiting for a shut-off notice, because it gives the department time to work with you rather than forcing them to follow collection procedures.
Paying a past-due balance
If your account is past due, you can pay the full amount owed through any of the standard payment methods: online, by phone, by mail, or in person. Online and phone payment are fastest because they process the same day and can restore service more quickly if it has been shut off. When you pay online, the system will show your past-due amount separately from your current bill amount — pay both to bring the account fully current.
If your water has been shut off due to non-payment, service restoration typically takes one business day after payment is received and processed. Some areas charge a reconnection fee in addition to the past-due balance, so ask about that when you pay. Once your account is current, you can set up autopay to prevent future late payments.
Paying by mail or in person
Mail payments should include your account number and the payment amount. Write the account number on the check or money order itself, and mail it to the address on your bill. Cobb County processes mail payments during business hours, and it typically takes 7 to 10 days from the time you mail it until it posts to your account. If your due date is fewer than 10 days away, mail is not a reliable option — use online or phone payment instead.
In-person payment at the Cobb County Water System office is immediate and requires no processing time. You can pay with cash, check, or debit card at the counter. Hours and location are available on cobbcountywater.com, and you'll need your account number or the bill itself to process the payment. This method is useful if you prefer to handle payment face-to-face or if you have questions about your bill that you want to discuss with a representative.
Frequently Asked Questions
Can I pay my Cobb water bill with a credit card?
Cobb County Water System does not accept credit cards directly through their website or phone line. You can pay with a debit card or bank account online and by phone. If you want to use a credit card, you would need to use a third-party payment processor that accepts credit cards and charges a fee for that service — check cobbcountywater.com to see if such an option is listed.
What if I pay online but my payment doesn't show up right away?
Online payments typically process the same day, but it can take up to 24 hours for the payment to appear in your account. If more than 24 hours have passed and you don't see the payment posted, log back into your account to confirm the transaction went through, or call 770-419-6000 to verify. Keep your confirmation number from the payment for reference.
How do I know if my water service will be shut off?
Cobb County sends a shut-off notice before disconnecting service, giving you time to pay. The notice will state the date service will be terminated if payment is not received. If you receive a shut-off notice, contact the department immediately — paying before the stated date will prevent disconnection.
Can I change my due date?
Your due date is set by Cobb County's billing cycle and is not typically changeable. However, if you have a specific reason for needing a different due date, call 770-419-6000 to ask whether an exception can be made. Setting up autopay is another option if the current due date doesn't work with your pay schedule.
What should I do if I think my bill is wrong?
Contact Cobb County Water System at 770-419-6000 to report a billing error. Have your account number and bill ready, and explain what seems incorrect — whether it's an unusually high usage charge, a duplicate fee, or something else. The department can review your account and adjust the bill if an error is found.
