Thank you for your request. Water and Sewer bills are sent out at the end of each month. Once you receive your first invoice, you may pay your bill online, set up auto-pay from a credit card or bank account and request paperless billing by going to NorthfieldIL.org. You will need your account number from your bill to register. Please don’t forget to purchase a vehicle sticker and register your pet. If you have any questions, please contact the Finance Department at (847) 446-9200.
