Cox Creek WWTP - Riviera Beach, Maryland Wastewater Treatment Plant

Cox Creek WWTP is a municipal wastewater treatment facility serving Riviera Beach and surrounding areas in Anne Arundel County, Maryland. The plant serves a population of over 107,000, placing it in the large agglomeration category under US regulatory frameworks. As a US facility, Cox Creek WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Maryland Department of the Environment. For plants of this scale, secondary treatment is typically required, with additional nutrient removal standards in sensitive watersheds like the Chesapeake Bay. The plant discharges treated effluent into the Chesapeake Bay watershed, a major estuary on the Atlantic coast. The bay supports diverse aquatic life, including blue crabs, oysters, and striped bass, and is subject to strict nutrient pollution controls under the Chesapeake Bay Total Maximum Daily Load (TMDL).

Cox Creek WWTP discharges into the Chesapeake Bay, the largest estuary in the United States. The bay receives drainage from a vast watershed spanning six states and supports critical habitats for fish, shellfish, and migratory birds. Nutrient pollution from wastewater is a key concern, and the plant's operations are regulated under the Chesapeake Bay TMDL to reduce nitrogen and phosphorus loads.
