Late water and sewer bills

Water and sewer bills are due 30 days from the date of issue. Payments received after the due date are subject to a penalty.

Unpaid water and sewer bills are treated as a lien against the property. They may also lead to penalty charges, possible service termination, and possible sale at the county’s property tax sale.

Tenant, owner, and moving questions

Water and sewer bills are issued to the deeded owner of the property. If a tenant is responsible for paying the bill, payment arrangements should be handled with the property owner or through the billing office.

If a property is sold, the settlement officer prorates the water and sewer bill based on average consumption. Tenants moving out should contact the property owner. Harford County lists a $50 charge for special meter readings.

Service availability and water issues

For public water or sewer availability, contact the Department of Public Works New Accounts Section. The county states that staff can tell you whether public water and/or sewer is available for a property and provide connection cost information if service is available.

For cloudy water, taste, or odor issues, Harford County lists a separate water quality phone number. For broken water mains, sewage backups, or other service-related emergencies, the Division of Water and Sewer lists an emergency reporting number.
