Normanton STW - Wastewater Treatment Plant in Wakefield, England

Normanton STW is a wastewater treatment plant located in Wakefield, West Yorkshire, England, United Kingdom. It serves a population of approximately 45,396 people, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD), which the UK has transposed into national law. The plant is situated inland, more than 50 km from the coast, and its treated effluent likely discharges into a local watercourse within the Humber River Basin. As a plant serving over 10,000 people, Normanton STW is required to meet secondary treatment standards under the UWWTD. The UK Environment Agency oversees permitting and compliance, ensuring that discharges do not harm the receiving water environment. The plant operates within a regulatory framework that mandates appropriate treatment levels to protect water quality. It is likely a tributary of the River Calder, which flows into the River Aire and eventually the Humber Estuary. This catchment supports diverse aquatic life and is important for migratory fish species. The plant's operation contributes to maintaining the ecological health of the downstream water bodies and the Humber Estuary, a major coastal feature.

Normanton STW discharges into a local watercourse within the Humber River Basin, likely a tributary of the River Calder. The Calder flows into the River Aire, which joins the River Ouse to form the Humber Estuary, a large tidal estuary that supports diverse birdlife and fish populations. The plant's treated effluent must meet standards to protect this downstream ecosystem, which is ecologically sensitive and important for migratory species.
