ILKESTON STW - Wastewater Treatment Plant in City of Nottingham, England

ILKESTON STW is a wastewater treatment plant located near Trowell in Nottinghamshire, England, serving a population of around 48,219. The facility is part of the municipal infrastructure for the City of Nottingham and is situated in the East Midlands region. Under the UK's transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), treatment plants serving populations over 15,000 are required to provide secondary treatment as a minimum. For agglomerations of this scale, the directive also mandates appropriate treatment to meet quality standards before discharge into receiving waters. The plant's treated effluent ultimately drains into the River Erewash, a tributary of the River Trent, which flows into the Humber Estuary and the North Sea. The River Trent supports diverse aquatic life and is an important ecological corridor in the region.

ILKESTON STW discharges into the River Erewash, which flows into the River Trent, a major river in the East Midlands. The Trent is a key waterway supporting fish populations and wetland habitats, and its waters eventually reach the Humber Estuary, a large estuarine ecosystem important for migratory birds and marine life.
