As always utility bill payments may be made in person at the Village Hall, sent by US Mail to Village Hall, or placed in our 24-drop box. We request you provide your remittance slip for ease of processing.
The drop boxes are located near the entrance of Village Hall on Cottonwood Avenue and also near the exit of the shared parking lot with the Hartland Public Library on Park Avenue. Payments deposited in the drop boxes on or before the due date will be considered paid on time. The drop boxes will be emptied each day at approximately 7:30 am and the payments are processed as the day prior
Late Payments
Payment must be received at Village Hall on or before the due date to avoid penalty assessments. The current penalty of 3% will be assessed to outstanding utility account balances, not paid by the due date.
