Where to pay your Gwinnett water bill
Gwinnett County Department of Water Resources lets you pay online through their website, by phone, by mail, or in person at a payment center. The online portal is the fastest option — you can pay immediately without waiting for mail delivery or phone lines. You'll need your account number, which appears on your bill.
If you prefer not to use the internet, you can call the customer service line at 770-904-3500 during business hours to pay by phone with a debit or credit card. Mail payments should be sent to the address printed on your bill, though they take 7 to 10 days to process. In-person payment centers are located in Lawrenceville and other county locations if you want to hand over a check or cash the same day.

- Phone payments at 770-904-3500 work during business hours and accept debit or credit cards, though you should allow time for processing.
- Mailed checks take 7 to 10 days to reach and process, so send them well before your due date to avoid late fees.
- Your account number appears on your bill and is required for any payment method you choose.
- Late payments typically trigger a penalty fee, so confirm your payment went through if you're paying close to the due date.
Setting up online payment through your account
To pay online, visit the Gwinnett County Department of Water Resources website and look for the customer portal or bill payment section. You'll enter your account number and either your service address or the phone number associated with your account. The system will pull up your current balance and allow you to pay the full amount or a partial payment.
You can pay with a debit card, credit card, or bank account transfer. Credit card payments may carry a convenience fee — check the payment screen before confirming. Bank account transfers typically have no fee and are the cheapest option if you have time before the due date. The system will give you a confirmation number immediately, which you should save or print for your records.
Paying by mail and what to include
If you mail a check, write your account number on the check itself. Include the payment stub from your bill in the envelope — this helps the county match your payment to your account quickly. Mail to the address shown on your bill, which is usually the Gwinnett County Department of Water Resources office in Lawrenceville.
Because mail takes time to arrive and process, send your payment at least 10 days before the due date. If you're mailing close to the deadline and want proof of timely payment, consider using certified mail or a service that provides tracking. Keep a copy of the check or a photo of it for your records until you see the payment reflected on your next bill.
Phone payment and what information you'll need
Call 770-904-3500 during business hours to pay by phone. Have your account number ready, along with your debit or credit card. The representative will confirm your service address and current balance before processing the payment. Ask for a confirmation number and the exact date the payment will post to your account.
Phone payments work well if you want to speak with someone about your bill or have questions about your account at the same time. However, if you call near the end of the business day, the payment may not process until the next business day. If your due date falls on a weekend or holiday, call a day or two early to make sure your payment clears on time.
In-person payment at Gwinnett County locations
You can walk into a Gwinnett County payment center and hand over cash, a check, or a card. The main office is in Lawrenceville, and satellite locations exist in other parts of the county. Bring your account number or your bill, and bring a valid ID if paying with cash. Payment is processed immediately, and you'll receive a receipt on the spot.
In-person payment is useful if you have questions about your bill or your account and want to resolve them face-to-face. It also eliminates the risk of mail delays or online system errors. Check the county website for the hours and locations of payment centers near you, as hours vary by location.
Understanding late fees and what happens if you miss the due date
Gwinnett County adds a late fee to your bill if payment is not received by the due date shown on your statement. The fee amount varies but is typically a percentage of your bill or a flat amount — check your bill or call customer service to confirm the exact fee for your account. Late fees compound if you continue to miss payments, and your account may be flagged for service disconnection if you fall significantly behind.
If you know you'll miss a due date, contact the county before the deadline to discuss a payment plan or extension. Some situations may allow you to avoid the late fee if you have a documented hardship. The sooner you contact them, the more options you may have. Once service is disconnected, you'll owe a reconnection fee in addition to your unpaid balance.
Setting up automatic payments to avoid missed due dates
Many water customers set up automatic payments through the online portal so they never have to remember the due date. You can choose to pay the full bill automatically each month or a set amount. The system will deduct the payment from your bank account or card on a date you select, usually a few days before the due date.
Automatic payments reduce the risk of late fees and disconnection. You can change or cancel the automatic payment at any time through your account. Review your bill each month to make sure the automatic payment amount is correct, especially if your usage changes seasonally. If you dispute a charge or notice an error, you can still contact customer service — automatic payment does not prevent you from questioning your bill.
Frequently Asked Questions
Is there a fee to pay my Gwinnett water bill online?
Online payment through the county website typically has no fee if you pay by bank account transfer. Credit card payments may carry a convenience fee of 2 to 3 percent — the payment screen will show this before you confirm. Check which payment method costs less if you're paying a large bill.
How long does it take for my payment to show up on my account?
Online payments usually post within one business day. Phone and in-person payments post the same day or next business day. Mailed checks take 7 to 10 days to arrive and process, so they may not show up for two weeks after you send them. If you're paying close to the due date, use online or phone payment instead.
What if I pay my bill but it still shows as late?
Contact customer service at 770-904-3500 to confirm the payment was received and processed. If the payment was mailed, it may still be in transit or processing. If the payment was made online or by phone, ask for the confirmation number and the date it will post. The county can usually reverse a late fee if the payment was made before the deadline but processed after.
Can I set up a payment plan if I can't pay my full bill?
Contact the Gwinnett County Department of Water Resources to discuss your situation. They may be able to work out a payment arrangement that lets you pay over time without immediate disconnection. The sooner you call, the more options you'll have. Waiting until after disconnection makes it harder to negotiate.
What happens if my payment is rejected?
If a card or bank account payment is declined, the system will notify you immediately. Check that your card or account information is correct and try again. If the problem persists, use a different payment method or call customer service. Do not assume the payment went through if you see an error message — verify it posted to your account before the due date.
