Sandy Hook WWTP - Secondary Wastewater Treatment in Sandy Hook, Maryland

Sandy Hook WWTP is a municipal wastewater treatment plant located in Sandy Hook, Washington County, Maryland, United States. The facility serves a small population of 145 residents and operates as part of the local wastewater infrastructure in the Potomac River watershed. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for most municipal facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 113.56 million gallons per year and currently discharges 49.21 million gallons annually, indicating it operates below its full capacity. The treated effluent from Sandy Hook WWTP is discharged into a local waterway that ultimately drains into the Potomac River and then into the Chesapeake Bay. The Chesapeake Bay is a large estuary that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. The plant's discharge contributes to the nutrient and pollutant load in the watershed, making its treatment performance important for downstream water quality.

Sandy Hook WWTP discharges into a tributary of the Potomac River, which flows into the Chesapeake Bay. The Chesapeake Bay is a major estuary that supports a complex ecosystem, including submerged aquatic vegetation, shellfish, and finfish. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia in the bay, so the plant's secondary treatment helps reduce organic and nutrient loads to protect downstream habitats.
