MALTBY STW - Wastewater Treatment Plant in Maltby, South Yorkshire, United Kingdom

MALTBY STW is a wastewater treatment plant located in Maltby, South Yorkshire, England, serving a population of approximately 33,840. The plant is situated inland, more than 50 km from the coast, and plays a key role in managing municipal wastewater for the local community. As a plant serving a medium-sized agglomeration, MALTBY STW is expected to meet secondary treatment standards under the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000, which aligns with the plant's scale. The treated effluent from MALTBY STW is discharged into local watercourses that ultimately drain into the North Sea via the River Don and Humber Estuary. The plant's operations help protect the water quality of these downstream environments, supporting aquatic life and recreational uses.

MALTBY STW discharges into local watercourses that flow into the River Don, a tributary of the River Trent, which then reaches the Humber Estuary and the North Sea. The Humber Estuary is a major ecological feature supporting diverse bird populations and fish species. The plant's treatment processes help reduce nutrient and pollutant loads, safeguarding the estuarine and marine ecosystems downstream.
