Office Responsibilities

One of the main responsibilities of this office is assessment and billing for all Metropolitan charges on the annual July 1 property tax bill. These charges are authorized by the Baltimore County Code 2015, Article 20 and the Executive Order. Property owners are urged to open their tax bill when received to review their annual charge since many tax bills are paid through a mortgage escrow.

  • Sewer Service Charges—This is an annual user fee billed on the July 1 Property Tax bill. It is based on the amount of water used and is assessed to recover the cost of treatment and transportation of wastewater.
  • Water Distribution Charges—This is an annual flat fee per water meter that supplies funds for major facilities such as pumping stations, transmission mains and storage facilities. The charge is determined by the size of the water meter servicing the property and is billed on the July 1 Property Tax bill.
  • Water and Sewer Benefit Assessments—These charges are applied on all properties within the Metropolitan District, improved and unimproved, to recover the construction costs of installing water and sewer mains, and are paid for a 40 year period. They are billed on the July 1 Property Tax bill.
  • Bay Restoration Fee (BRF)—The State of Maryland established this fee in 2004 to create a dedicated fund to upgrade Maryland’s wastewater treatment plants,  enable septic system users to upgrade onsite systems, and implement cover crops to reduce nitrogen loading to the Bay. It is billed on the July 1 Property tax bill.
  • Other Metro District Charges—Water and Sewer connection charges, System charges and Deficit charges.

Other Responsibilities

  • Handling inquiries for water and sewer availability.
  • Receiving and processing requests for petitions to extend public sewer and water lines.
  • Administering and coordinating design and construction of health-related and citizen-financed projects for sewer and water lines with other County agencies, securing methods of funding and repayment, and conducting public meetings to explain costs and payment options available to property owners.
  • Calculating and billing Food Service Surcharge for food service businesses.
  • Billing Industrial Wastewater surcharges.
  • Calculating and administering Wastewater Credit Allowances.
  • Administering residential swimming pool wastewater credits.
