Annual LID Invoices for 2025 (clarification)

April 22, 2025

All LID invoices were mailed out today!

If you are enrolled in e-billing for sewer user fees, you will not receive an email for this invoice. The LID is separate and is not billed through our utility billing software. Therefore, LID payments cannot be made via the customer portal.

LID payments are due by 6/13/25. 

Please reach out if you have any questions.

Thank you,
