You can pay your water/sewer utility bill at City Hall during normal business hours with cash, check, money order, debit or credit card. We now accept Visa, Mastercard and Discover so you can call in to make a payment or go online and make the payment with Xpress Bill Pay. This can also be set up as an auto-pay method. Whenever you pay with a card there is a 2.8 percent convenience fee that is applied and paid directly to the credit card processor at the time of the transaction. The City of Oak Grove does not receive any of these monies from the convenience fee. We also have a drop box under the portico in front of the building which can be used after hours payments.
