City of Monmouth

Welcome to the Maple City!

Pay Your Water Bill Online

You can pay your water bill online at any time. To use the online payment portal, you will need the Book and Account numbers from your water bill. You will also need a PIN number for your account. You can get your PIN number by calling the water department (309-734-2035) and letting them know the address. All major credit cards are accepted. Online payments will have a $4.00 convenience fee added to the total (by Donald Frey & Co., not the City of Monmouth).

To pay online, click here.

You can also set up Automatic Payments directly with the City at no charge to you. You'll need to come in to the water department with a valid photo ID and a voided check. Automated payments are taken directly from your account on the 5th of each month for the exact amount of your water bill.
