Log in to GCWW's online portal to pay your bill
Greater Cincinnati Water Works (GCWW) lets you pay your bill through their website without calling or mailing a check. You log in with your account number and create a password, then you can pay immediately or set up a recurring payment.
The portal is at www.gcww.org. Look for the "Pay My Bill" or "Customer Portal" link on the homepage. You will need your GCWW account number, which appears on your printed bill in the upper right corner or on any past statement.
If you do not have an online account yet, you will create one the first time you visit. GCWW will ask for your account number, service address, and a password you choose. Once that is set up, you can log in anytime to view your balance and payment history.
Key Takeaways
- You can pay your GCWW bill online at www.gcww.org by logging in with your account number and a password you create.
- One-time payments process immediately, and you can choose to pay the full balance or a partial amount.
- Setting up automatic recurring payments means your bill gets paid on the same day each month without you having to log in again.
- If you forget your password, GCWW's portal has a reset option that sends instructions to the email address on file.
What information you need before you log in
Gather these details before you start: your GCWW account number (on your bill), your service address, and an email address where GCWW can send you a password reset link if you need one later.
Your account number is the fastest way to find your account in the system. If you have moved recently or have multiple properties, make sure you are using the account number for the address you want to pay. GCWW will not let you pay a bill for an address that is not linked to your login.
How to make a one-time payment
After you log in, select "Pay My Bill" or "Make a Payment." The portal will show your current balance and due date. You can pay the full amount or enter a different amount if you want to pay only part of what you owe.
GCWW accepts payments by bank account (ACH transfer) or debit card. Bank account payments usually process the same day or the next business day at no charge. Debit card payments process immediately but may carry a small fee — GCWW will show you the fee amount before you confirm.
After you submit the payment, you will see a confirmation number on screen. Write it down or take a screenshot. GCWW will also email a receipt to the address on your account.
Setting up automatic monthly payments
If you want your bill paid the same day each month without logging in, you can set up autopay through the portal. Select "Enroll in AutoPay" or "Automatic Payments" and choose the day of the month you want the payment to come out.
You can choose to pay your full bill each month or a fixed amount. If you choose a fixed amount and your bill changes, you will still owe the difference — autopay does not cover a shortfall. You can change or cancel autopay anytime by logging back in.
Autopay uses the same payment method you select (bank account or debit card). If you use a debit card, the fee applies each month, so a bank account is usually cheaper over time.
What to do if you cannot log in
If you forget your password, click "Forgot Password" on the login page. GCWW will send a reset link to the email address on your account. Check your spam folder if you do not see it within a few minutes.
If you do not remember your account number, call GCWW's customer service at 513-591-6000. They can look up your account by your service address and phone number. Have your bill or a recent statement handy so you can confirm your address quickly.
If the portal is down or you cannot access it for another reason, you can still pay by phone at 513-591-6000 or by mail. Mail payments should be sent to the address on your bill and take 7 to 10 business days to post to your account.
Payment timing and when your bill is due
GCWW bills are usually due 20 days after the bill date. The due date is printed on your bill. If you pay online, the payment posts to your account the same day or the next business day, so you have a small window to pay after the due date without a late fee — but do not count on it.
If your payment is late, GCWW charges a late fee. The amount varies, but it is usually a percentage of your bill or a flat fee. Check your bill or call customer service to find out what the current late fee is.
If you are having trouble paying your bill on time, GCWW may have a payment plan or hardship program. Call 513-591-6000 to ask about your options before you miss a payment.
Frequently Asked Questions
Can I pay my GCWW bill without creating an online account?
Yes. You can pay by phone at 513-591-6000, by mail to the address on your bill, or in person at a GCWW office. Online is fastest, but these other methods work if you do not want to set up a login.
Is there a fee to pay my bill online?
Bank account payments (ACH) have no fee. Debit card payments carry a small fee that GCWW shows you before you confirm the payment. The fee varies depending on the payment amount.
What happens if I set up autopay and then move?
Autopay will stop when your service ends at that address. When you set up service at your new address, you will need to log in with your new account number and enroll in autopay again if you want it.
Can I see my payment history online?
Yes. After you log in, your account dashboard shows recent payments, due dates, and your balance. You can usually download or print a statement from the portal as well.
What if I overpay my bill?
The extra amount stays on your account as a credit and applies to your next bill. If you want a refund instead, call GCWW at 513-591-6000 to request one.
