HEAGE STW - Secondary Wastewater Treatment in Amber Valley, Derbyshire

HEAGE STW is a wastewater treatment plant located in Nether Heage, Amber Valley, Derbyshire, England. It serves a population of around 2,600, making it a small agglomeration under UK regulatory frameworks. The plant is situated inland, away from coastal areas, and its operations are part of the regional water infrastructure managed by the local water authority. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 4,000 cubic meters per day and an average discharge volume of 581 cubic meters per day, the facility operates well within its capacity. The treatment process ensures that effluent meets regulatory standards before release. The treated wastewater from HEAGE STW is discharged into local rivers that flow through the Derbyshire countryside, eventually reaching the North Sea via the River Trent and Humber Estuary. The plant plays a key role in protecting the water quality of these downstream environments, supporting aquatic life and recreational uses in the region.

HEAGE STW discharges into local watercourses that drain into the River Derwent and then the River Trent, which flows into the Humber Estuary and the North Sea. The surrounding watershed supports diverse freshwater habitats, including fish populations and riparian ecosystems. The plant's secondary treatment helps reduce nutrient loads and organic pollutants, safeguarding water quality in this ecologically sensitive river system.
