CROWLAND STW - Crowland, South Holland, Lincolnshire Wastewater Treatment Plant

CROWLAND STW is a wastewater treatment plant located in Crowland, South Holland, Lincolnshire, England. It serves a population of approximately 3,788 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The plant has a designed capacity of 3,788 population equivalents and discharges an average of 843.34 cubic meters of treated effluent per day. The treated effluent is discharged into local watercourses that drain into the River Welland and eventually The Wash, a large estuary and embayment of the North Sea. The Wash supports diverse aquatic life and is an important area for migratory birds and marine species.

The plant discharges into the River Welland catchment, which flows into The Wash, a major estuary on the east coast of England. The Wash is ecologically sensitive, supporting diverse aquatic life, including important fish populations and migratory bird species. The surrounding Lincolnshire Fens are a low-lying agricultural region where water quality management is critical to prevent nutrient enrichment in downstream waters.
