SAXILBY STW - Secondary Wastewater Treatment Plant in West Lindsey, England

SAXILBY STW is a wastewater treatment plant located in West Lindsey, Lincolnshire, England, serving the local community of Saxilby with Ingleby. The plant provides secondary treatment for a population equivalent of approximately 4,019 people, operating under the regulatory framework of the United Kingdom. The plant has a designed capacity of 4,036 m³/day and currently discharges an average of 894.77 m³/day of treated wastewater. As a secondary treatment facility, it meets the minimum treatment standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC), which the UK has retained in domestic law. For agglomerations of this size (under 10,000 population equivalent), secondary treatment is the standard requirement unless the receiving waters are designated as sensitive. The treated effluent from SAXILBY STW is discharged into local watercourses that ultimately drain into the River Trent and then into the Humber Estuary, which flows into the North Sea. This catchment supports diverse aquatic life and is an important ecological corridor. The plant's operation helps protect downstream water quality and the broader Humber ecosystem.

SAXILBY STW discharges into local watercourses that feed into the River Trent, a major river in the Midlands that flows into the Humber Estuary and then the North Sea. The Humber Estuary is a large, ecologically important system supporting diverse fish, bird, and invertebrate populations. The plant's secondary treatment helps reduce organic pollution and nutrient loads, contributing to the health of this downstream environment.
