BUCKLEY STW Wastewater Treatment Plant, Buckley, Wales

BUCKLEY STW is a wastewater treatment plant located in Buckley, Flintshire, Wales, serving a population of around 14,791. The facility is situated inland, away from the coast, and plays a key role in managing municipal wastewater for the local community. As a medium-sized agglomeration, the plant is expected to provide at least secondary treatment under the EU Urban Waste Water Treatment Directive (91/271/EEC), which is transposed into UK law. The treated effluent is discharged into local watercourses that ultimately drain into the Dee Estuary and the Irish Sea. This discharge supports the ecological health of the River Dee catchment, which is important for aquatic biodiversity and downstream water quality.

The plant discharges into the River Dee catchment, which flows into the Dee Estuary and then the Irish Sea. The Dee Estuary is an ecologically sensitive area supporting diverse birdlife and fish populations, including salmon and sea trout. The treatment plant's operations help protect these downstream habitats from nutrient pollution and pathogens.
