Ready-To-Serve Charge

There are two components to this charge: (1) the existing Account Maintenance Fee (AMF) which covers the cost to bring water and sewer service to every home and business; including meters, meter readers and billing; and (2) Infrastructure Investment Fee (IIF) which is allocated to the replacement/rehabilitation of system infrastructure.

The AMF is an average of $16 per quarter. The IIF* is an average of $12 per quarter. Total savings for CAP customers is an average of $28 per quarter or $112 per year.

* The IIF increased $6 per quarter in Fiscal Year 2017.

NOTE: If you are approved for CAP, you are automatically eligible for exemption from the $15 per quarter or $60 per year Chesapeake Bay Restoration Fund fee, which WSSC Water administers on behalf of the State of Maryland.
