Water and sewer services are provided and billed by two separate entities. Water service and billing is provided by the Boonsboro Keedysville Regional Water Board (BKRWB). Sewer service and billing is provided by the Washington County Department of Water Quality. Both services are billed quarterly and based on water usage. Please be sure to send your payments to the appropriate provider. Sending your payment to the wrong provider could cause delays in your payment being received and result in late fees. The BKRWB may be contacted at 301-432-5141. The Wash. Co. Dept. of Water Quality may be contacted at 240-313-2317.
