Millington_Sandfield WWTP - Sudlersville, Maryland Wastewater Treatment Plant

Millington_Sandfield WWTP is a municipal wastewater treatment facility located in Sudlersville, Queen Anne's County, Maryland. The plant serves a small population of 470 residents, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal facilities. Its designed capacity of 397.47 units and current discharge volume of 208.20 units indicate it is operating below capacity. As a small agglomeration, it is subject to EPA NPDES permitting through the Maryland Department of the Environment. The treated effluent is discharged into local waterways that drain into the Chesapeake Bay watershed. The Chesapeake Bay is the largest estuary in the United States and an ecologically sensitive ecosystem that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. The plant's nutrient removal performance is critical for reducing pollution loads to the bay.

The plant discharges into tributaries of the Chester River, which flows into the Chesapeake Bay. The Chesapeake Bay is a vital estuary that supports diverse aquatic life, including blue crabs, striped bass, and oysters. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia, making advanced treatment important for bay health.
