Account Handling
The billing section currently handles approximately 39,000 accounts: 800 water-only accounts, 10,200 sewer-only accounts, and 28,000 water and sewer accounts. The accounts are divided into three regions and are billed on a staggered quarterly cycle.

The sewer-only accounts are currently billed quarterly. The customers having a sewer-only account should be aware that their water service may be provided by an independent municipality (such as the City of Frederick, the Town of Walkersville, or the City of Brunswick) that is not affiliated with the Division of Water and Sewer Utilities and is operated by its own respective billing department. Therefore, questions regarding water services in these areas should be directed to the appropriate municipality.

Pursuant to §2-13-24 of the Public Local Laws, all bills are liens against the property and are subject to inclusion in the County’s annual tax sale.


The Office of Accounting and Finance Support currently provides support services to the various departments of the Division of Water and Sewer Utilities for water and sewer activities. The primary responsibilities for this office are:

  • Customer Service/Service Billing/Collection
  • Capacity Fee Calculation/Collection
  • Contract Administration
