Can I schedule future payments and not worry about my bills?

Yes. You can use the Manage Payments option and select a future date. The payment will be processed on the selected date.

How are my water charges calculated?

Water charges consist of two separate parts: water usage and service availability. The service availability or the base charge is a fixed amount that is paid for the connection to the public water system. This fixed amount includes all operational and maintenance costs. The water usage charge depends on the amount of water consumed.

How can I know when I will have my water meter read by the Cincinnati Water Department?

GCWW customers are typically billed once every three months. If you want to find the precise date of your next water meter reading, you will need to enroll in the myGCWW Customer Care Portal.

Is the water safe to drink?

GCWW prioritizes safe drinking water. Their system conducts around 600 tests on a daily basis to ensure that the water is always safe to drink. Source waters are tested before they enter the treatment plants and experts test the water after each phase of the treatment process. GCWW collects water samples from the distribution system to continuously monitor the water quality after it leaves the treatment factory.
The water from GCWW meets or exceeds all health standards developed by USEPA.

My water turns brownish from time to time, should I report this to the Cincinnati Water Department?

Water can become reddish or brownish due to the rust from corrosion in the pipes. However, this is not a health concern – the water still meets all health regulations.
If you have questions or your laundry is stained from rusty water, you can call the GCWW Customer Service at 513-591-7700. They will send you laundry aid to remove the rust from the clothes. If you notice rusty water in your faucets, you can run cold water for a few minutes. Chances are the water will become clear again.

My drinking water looks cloudy, is this an issue?

No. Cloudy water is caused by tiny air bubbles in the water. The bubbles naturally rise to the surface and disappear into the air. This does not change the water safety.
If you have any additional questions, you can call the GCWW Customer Service at 513-591-7700.

What if I experience trouble logging into myGCWW Customer Care Portal?

How can I add multiple accounts to my profile?

You do not have to enroll each account individually. When you register, all your accounts will become available. If you have multiple GCWW accounts, you will simply enter the account number of your additional properties during the enrollment process. If you can’t find one of your accounts, you can use the moving form to move the account under your name.

I’ve made a payment, but I’m not sure it posted to the Cincinnati Water Department how can I verify?

If your payment goes through you will be given a receipt after you confirm the payment. You will also receive a confirmation email notifying you of the payment. In case you want additional confirmation, you can check out the account summary tab and view the last payment received and payment date to confirm that the payment went through.

I want to cancel a payment, how can I do that?

You can press Cancel Payment in the Account Summary tab to cancel a scheduled payment. However, you cannot cancel payments that were made in the past or on the same day.

I’ve decided to move, do I have to enroll in the myGCWW program again?

No. You can fill out the moving form and all of your accounts will automatically be updated.

I want to pay my bill, what are my payment options?

How can I know if my bill was sent to me, when are the bills due?

Bills are sent out to consumers within five days of the meter reading. They are due 21 after they are produced.

I think there’s a water main leak or break, can I report the potential issue?

Yes. You can call 513-591-7700, 24/7, in case of emergency. Please provide the precise address and the nearest cross street. GCWW is bound to investigate all reported leaks and breaks. However, the property owners are responsible for all plumbing on their private properties. The owners are also responsible for protecting the water meter.

Why is fluoride added to my water?

A state law passed in 1969 requires all water systems to add fluoride to their water to protect teeth. According to the American Dental Association, people who drink water enriched with fluoride have 20% to 40% less cavities. However, home filtration devices can still remove the fluoride from water.
