DROPE STW Westbury Homes Glamorgan STW - Cardiff, Wales Wastewater Treatment Plant

DROPE STW Westbury Homes Glamorgan STW is a wastewater treatment plant located in the St Fagans area of Cardiff, Wales, United Kingdom. The facility serves a population equivalent of approximately 2,011 people, classifying it as a small agglomeration under UK wastewater management frameworks. The plant is situated near the coast, within 10 km of the sea, which influences its discharge requirements. The plant provides secondary treatment, a standard level for small communities under the UK's implementation of the EU Urban Waste Water Treatment Directive (now retained as domestic law). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 2,011 population equivalent, and it reports a discharge volume of 447.72 (likely in cubic meters per day or similar unit). Treated effluent from the plant is discharged into local watercourses that ultimately drain into the Bristol Channel, a major estuary and important ecological area. The coastal location means the plant must meet stringent standards to protect marine water quality and sensitive habitats. The plant contributes to safeguarding the health of the Severn Estuary ecosystem, which supports diverse aquatic life and migratory bird populations.

The plant discharges into local watercourses that flow into the Bristol Channel, part of the Severn Estuary system. This estuary is ecologically sensitive, supporting diverse fish, bird, and invertebrate communities. The coastal discharge location requires careful management to prevent nutrient enrichment and protect marine habitats. The plant's secondary treatment helps reduce organic pollutants before release into this dynamic tidal environment.
