District Authorization

Queen Anne's County is declared to be a Sanitary District but does not exercise any authority over the facilities within any incorporated municipality. The provisions of Title 24, Code of the Public Local Laws of Queen Anne's County, are under the jurisdiction and control of the County Commissioners who sit as the Sanitary Commission.

The County is expressly authorized and empowered to establish, construct, locate, maintain, operate, protect, preserve, repair, replace, extend, or enlarge any solid waste system, disposal system, sanitary landfill, water supply system, or sewer system that may be required for any of the purposes of Title 24. While solid waste is included by code under the Sanitary District, the Solid Waste Division, a General Fund Department, in fact handles all solid waste operations.

Wastewater Treatment Plant

The Sanitary District currently operates and maintains 1 wastewater treatment plant divided into 4 wastewater subdistricts. The Kent Narrows / Stevensville / Grasonville (KN/S/G) treatment plant has a 3.0 MGD capacity and includes the KN/S/G, Cloverfields, and Bay City Subdistricts. With the elimination of the Prospect Bay wastewater treatment plant, and the combination of the service area with KN/S/G, Prospect is now the fourth subdistrict. The same 4 areas also serve as water subdistricts:

  • Kent Narrows / Stevensville / Grasonville
  • Cloverfields
  • Bay City
  • Prospect Bay (Prospect’s water subarea has also been combined with KNSG)

Kent Narrows / Stevensville / Grasonville Subdistrict

The KN/S/G Wastewater Subdistrict service area is composed of an 8 mile long by 3 mile wide strip along the Route 50 / 301 corridor from Stevensville through Grasonville. The Cloverfields and Bay City Subdistricts extend North and South of Route 50 / 301 along Route 18 and Route 8, respectively. The KN / S / G treatment plant serves approximately 5,600 sewer accounts which includes 5,900 dwellings.
