TUPTON STW - Wastewater Treatment Plant in North East Derbyshire, England

TUPTON STW is a wastewater treatment plant located in Grassmoor, North East Derbyshire, England, serving a population of around 10,356. The facility is part of the United Kingdom's wastewater infrastructure, operating under the regulatory framework of the Water Industry Act 1991 and the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. As a medium-sized agglomeration, the plant is expected to provide secondary treatment as a minimum, in line with UK regulations. The plant's scale suggests it likely employs biological treatment stages to meet consent conditions set by the Environment Agency. The treated effluent is discharged into local water bodies that drain into the River Rother, a tributary of the River Don, which flows into the Humber Estuary and ultimately the North Sea. The plant plays a key role in protecting the water quality of these downstream environments, supporting aquatic life and recreational uses.

The plant discharges into the River Rother catchment, which flows into the River Don and then the Humber Estuary, a major ecological feature supporting diverse birdlife and fish species. The Humber Estuary is a vital migratory corridor for salmon and eels, and its mudflats and saltmarshes provide critical habitat for wading birds. Protecting water quality in this system is essential for maintaining biodiversity and supporting local fisheries.
