Pay your Gwinnett County water bill through the city's online portal, by phone, or by mail
Gwinnett County Department of Water Resources (often called GWinnett H2O) accepts payments through multiple channels. The fastest and most convenient method is their online payment portal at gwinnettcounty.com, where you can pay immediately with a bank account or debit card. You can also pay by phone, automatic bank draft, or traditional mail — each method has different timing and fees.
Your bill arrives monthly and shows your water usage, sewer charges, and any fees. The due date is printed on the front of your bill. Payments made online or by phone typically post within one business day. Mail payments take 7 to 10 business days to reach the county, so send them early if your due date is approaching.

Paying online through the Gwinnett County portal
Log in to gwinnettcounty.com and select the water bill payment option. You will need your account number, which appears on the front of your bill. The portal accepts payments from a checking or savings account (no fee) or a debit or credit card (a convenience fee applies — the exact amount depends on your card type and is shown before you confirm).
Online payments post the same business day if submitted before 5 p.m. Eastern Time on a weekday. Payments made after 5 p.m. or on weekends post the next business day. You will receive an immediate confirmation number on screen and a receipt by email.
If you do not have an online account yet, you can create one using your account number and the service address on your bill. The county also offers a guest checkout option if you prefer not to save login information.
Setting up automatic monthly payments
Automatic bank draft is the most reliable way to ensure you never miss a due date. You authorize Gwinnett County to withdraw the bill amount directly from your checking account on a date you choose — usually a few days before the due date. There is no fee for this service.
To enroll, call the Gwinnett County Department of Water Resources at 678-376-6701 and ask for automatic payment setup. You will need to provide your bank account number and routing number. The county will send you a confirmation letter with the withdrawal date and amount.
You can change or cancel automatic payments at any time by calling the same number. Keep in mind that if your account balance is too low on the withdrawal date, your bank may decline the payment and charge you an overdraft fee — the county is not responsible for bank fees.
Paying by phone or in person
Call 678-376-6701 to pay by phone using a debit or credit card. A convenience fee applies and will be stated before you complete the transaction. The payment posts immediately, and you will receive a confirmation number.
In-person payments are accepted at the Gwinnett County Department of Water Resources office, located at 410 South Perry Street, Lawrenceville, GA 30046. Hours are Monday through Friday, 8 a.m. to 5 p.m. You can pay by cash, check, or card. Payments made in person before 5 p.m. post the same day.
Paying by mail
Write a check or money order payable to "Gwinnett County" and include your account number on the back. Mail it to:
Gwinnett County Department of Water Resources P.O. Box 1052 Lawrenceville, GA 30046
Mail payments take 7 to 10 business days to arrive and post. To avoid a late fee, mail your payment at least two weeks before the due date. Do not send cash by mail. Keep a copy of your check or money order number for your records.
Understanding late fees and service disconnection
A payment is late if it is not received by the due date printed on your bill. Late payments trigger a 10 percent penalty added to your next bill. For example, a $100 bill becomes $110 if paid late.
If your account falls 30 days past due, the county will send a notice. If you reach 60 days past due, your water service can be disconnected without further notice. Reconnection requires payment of the full past-due balance plus a reconnection fee (the amount varies but is typically $75 to $150).
If you are struggling to pay, contact the Department of Water Resources at 678-376-6701 to ask about payment arrangements or hardship programs. The county may be able to work out a plan rather than disconnect your service.
Reading your Gwinnett County water bill
Your bill shows your account number, service address, and billing period at the top. Below that, you will see separate charges for water usage (measured in hundred-cubic-foot units, or HCF), sewer service, and any additional fees. The due date and total amount due are highlighted on the front.
Water usage is billed on a tiered rate structure — the more water you use, the higher the per-unit cost. Your bill breaks down usage by tier so you can see how much you used in each price bracket. Sewer charges are typically a flat fee or based on your water usage.
If you notice an unusually high bill, check for a leak (a running toilet or dripping faucet can add hundreds of gallons per month). You can also request a meter test by calling 678-376-6701 if you believe the reading is incorrect.
