Payment Information

Quarterly bills are mailed the first business day of January, April, July and October. Please call the billing office to request a copy if it is not received by the 10th of the month. Payments are due by the 30th of the billing month (by January 30, April 30, July 30, and October 30). The following payment options are available for your convenience:

Check Payments

Checks should be made payable to Calvert County Treasurer and may be mailed or made in person between the hours of 8:30 to 4:30 Monday through Friday at 175 Main Street, Prince Frederick, MD 20678. After business hours, payments may be placed in the black mailbox located in front of the courthouse.

Credit Card Payments

Visa, MasterCard, and Discover credit card payments may be made through our online portal eGovPlus. Find out how to activate your account by viewing the activation guide (PDF). A 3% convenience fee will be charged to your credit card at time of check out.

ACH Payments

Our automated payment option is a convenient and time-saving way to pay your water and sewer bill and may be set up to deduct the amount of your bill directly from your checking account each quarter.

Bill Pay

Online bill pay is available through many banks. Please check with your bank for details. Note that this form of payment often takes longer than standard payment methods. Allow two weeks from the online request date for the county to receive payment.  


Bill payment installments are welcomed. The account must be fully paid by the final due date to avoid interruption of service.

Delinquent Bills

Delinquent bills are sent out as reminders within one week of the original bill due date. Follow-up final notifications are mailed at least two weeks before the service termination date to ensure delinquent customers are aware of non-payment in time to prevent shut off. A charge will be assessed on accounts that are not paid by noon on the date noted on the final notification, which is the final payment date. This charge can be paid the next billing cycle. View our rate changes for additional information.

Service Shut-Offs

Service shut-offs will begin the day after final payments are due. Final payment is due by noon the day prior to shut-offs. Delinquent accounts will be charged a fee even if service is not shut off.

In order for service to be restored the same business day, bills must be paid before noon. If paid after noon, service will be restored within 24 hours. Telephone extensions for payment will no longer be granted.
