Paper Billing Information

When a customer wishes to establish new service or request change in service information the customer will automatically receive a paper bill in the mail on a quarterly basis. Bills are mailed around the middle of the month in February, May, August and November with payment due on the first Friday of the following month. The department will only bill full quarter charges and a one quarter in arrears. A prorated bill will be calculated for new home purchases with the bill settled at the closing transaction with the buyer being responsible for the next full quarterly bill after purchasing the home.

Payments must be exact, no partial payments will be accepted. The exact cash or check may be paid in person at the Treasurer’s office located at 301 N. Main St, Ste 203, Lima OH 45801, Monday – Friday 8 a.m. – 4:30 p.m. Credit/Debit Card Payments are accepted either on our “Pay Bill Now” link or by calling 1-866-636-3868.
