Wilberfoss STW - Secondary Wastewater Treatment Plant in Wilberfoss, East Riding of Yorkshire

Wilberfoss STW (Sewage Treatment Works) is a municipal facility located on Hull Road in Wilberfoss, East Riding of Yorkshire, England. The plant serves a population of approximately 2,786 residents and operates under secondary treatment standards, which involve biological processes to reduce organic matter and suspended solids. Its designed capacity is 2,810 cubic meters per day, with a reported discharge volume of 620.26 cubic meters per day. As a secondary treatment plant in the United Kingdom, Wilberfoss STW complies with the Urban Waste Water Treatment Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For a population equivalent of around 2,800, secondary treatment is the required standard, ensuring effective removal of biodegradable pollutants before discharge. The plant is operated as part of the regional wastewater infrastructure managed by Yorkshire Water, the local water and sewerage company. The treated effluent from Wilberfoss STW is discharged into local watercourses that ultimately drain into the Humber Estuary via the River Derwent and the Humber River system. The Humber Estuary is a major ecological feature supporting diverse bird populations and fish species, including migratory salmonids. The plant's discharge contributes to the overall water quality management in the catchment, which is subject to environmental monitoring under the Water Framework Directive.

Wilberfoss STW discharges into local streams that feed into the River Derwent, a tributary of the Humber Estuary. The Humber Estuary is a large, ecologically significant water body that supports internationally important bird populations and fish species. The plant's secondary treatment helps protect downstream water quality in this sensitive estuarine environment, which is designated as a Site of Special Scientific Interest (SSSI) for its wildlife and habitats.
