WHITWELL STW - Secondary Wastewater Treatment Plant in Bolsover, Derbyshire

WHITWELL STW is a municipal wastewater treatment plant located near Bolsover in Derbyshire, England. The facility serves a population of around 4,057 and operates under the regulatory framework of the UK Environment Agency, which enforces standards aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC) for secondary treatment. The plant provides secondary treatment, a standard requirement for inland freshwater discharges in the UK. With a designed capacity of 6,000 cubic meters per day and an average discharge volume of 903.23 cubic meters per day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local rivers that eventually drain into the North Sea via the Humber Estuary. The plant plays a key role in protecting the water quality of the River Rother and its tributaries, which support diverse aquatic life and are used for recreation and agriculture.

WHITWELL STW discharges into the River Rother catchment, which flows into the River Don and ultimately the Humber Estuary and North Sea. The local watershed is ecologically sensitive, supporting fish populations and wetland habitats. The plant's secondary treatment helps reduce nutrient loads and organic pollutants, safeguarding downstream water quality.
