LEVEN STW Wastewater Treatment Plant, Leven, East Riding of Yorkshire

LEVEN STW is a wastewater treatment plant located in Leven, a village in the East Riding of Yorkshire, England. The plant serves a population of 2,461 and operates under secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. The facility has a designed capacity of 2,606 m³/day and currently discharges 547.90 m³/day of treated effluent. As a secondary treatment plant, LEVEN STW provides biological treatment to reduce organic matter and suspended solids. The plant is situated near the coast, within 10 km of the North Sea, which influences its discharge requirements. Under UK regulations, coastal discharges must meet stringent standards to protect marine environments, and the plant's secondary treatment level aligns with these requirements. The treated effluent from LEVEN STW ultimately reaches the North Sea, a productive marine ecosystem that supports diverse fish populations and migratory bird species. The plant's location in a rural area near the Humber Estuary means its discharge contributes to the overall water quality of the region, which is important for both ecological health and local economic activities such as fishing and tourism.

LEVEN STW discharges treated wastewater into the local watercourse that drains into the North Sea via the Humber Estuary. The North Sea is a semi-enclosed continental shelf sea with significant ecological importance, supporting fisheries, seabird colonies, and marine mammals. The plant's coastal proximity means its effluent must meet strict environmental standards to prevent nutrient enrichment and protect sensitive habitats in the estuary and coastal zone.
