WSSC Water has a Customer Assistance Program (CAP) that provides financial assistance to approved residential customers. If you are enrolled in the Office of Home Energy Program (OHEP), you qualify for CAP. To date, the WSSC Water CAP has assisted nearly 14,000 customers and has significantly increased the number of customers who benefit from the Bay Restoration Fund fee exemption.

NOTE: Please confirm that your OHEP enrollment is current to ensure that you continue to receive the WSSC Water CAP credit.

CAP-approved customers will receive a credit on water and sewer bills to cover the Ready to Serve Charges, which are outlined below. These customers will only be charged for their water and sewer usage. Customers can then further reduce their bills through conservation.
