SWINESHEAD STW - Boston, Lincolnshire Wastewater Treatment Plant

SWINESHEAD STW is a wastewater treatment facility located in Boston, Lincolnshire, England, serving a population of approximately 3,057. The plant provides secondary treatment, a standard level for communities of this size in the United Kingdom. The plant has a designed capacity of 3,057 population equivalent and discharges an average of 680.59 cubic meters of treated wastewater per day. As a UK facility, it operates under the Urban Waste Water Treatment Regulations, which transpose the EU Urban Waste Water Treatment Directive, requiring secondary treatment for inland discharges from agglomerations of this scale. The treated effluent is discharged into local watercourses that drain into The Wash, a large estuary and bay on the North Sea coast. The Wash is an ecologically important area supporting diverse birdlife and marine habitats, making proper treatment essential for protecting downstream water quality.

The plant discharges into local watercourses that flow into The Wash, a major estuary on the east coast of England. The Wash supports extensive salt marshes and mudflats, providing critical habitat for migratory birds and marine species. The area is part of the Greater Lincolnshire wetland ecosystem, where nutrient management is important to prevent eutrophication in the coastal environment.
