Westfield STW Wastewater Treatment Plant, Rother, East Sussex

Westfield STW is a wastewater treatment plant located in Westfield, near Rother, East Sussex, England. The facility serves a population of 2,228 and provides secondary treatment, which is the standard biological treatment stage required for organic matter reduction. The plant's designed capacity is 2,228 population equivalent, and it discharges a daily volume of 496.03 cubic meters. As a plant in the United Kingdom, Westfield STW operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The UK's Environment Agency enforces compliance through discharge permits, ensuring treated effluent meets quality standards before release. The plant is located within 10 km of the coast, indicating its discharge likely reaches the English Channel via local watercourses. This proximity to marine waters necessitates careful management to protect coastal ecosystems, including habitats for seabirds and marine life. The receiving water body supports local biodiversity and contributes to the broader health of the Channel's coastal environment.

Westfield STW discharges treated wastewater into local watercourses that flow toward the English Channel, a major marine ecosystem supporting diverse fish, seabird, and invertebrate populations. The coastal environment is ecologically sensitive, with habitats such as salt marshes and mudflats that rely on good water quality. The plant's secondary treatment helps reduce organic pollutants, but its coastal location means nutrient and pathogen control are critical to prevent eutrophication and protect bathing waters.
