Towcester STW - Wastewater Treatment Plant in Shutlanger, West Northamptonshire, England

Towcester STW is a wastewater treatment plant located in Shutlanger, West Northamptonshire, England, serving a population of around 10,191. The plant is part of the UK's wastewater infrastructure, managed under the Water Industry Act 1991 and regulated by the Environment Agency. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the Urban Waste Water Treatment Directive (91/271/EEC), which is transposed into UK law. The plant's scale suggests it employs conventional biological treatment methods typical for inland plants of this size. The treated effluent likely discharges into a local watercourse within the River Great Ouse catchment, which flows into The Wash and ultimately the North Sea. The plant plays a key role in protecting local water quality and supporting the ecological health of the downstream river system.

The plant is situated inland in the River Great Ouse catchment, which drains into The Wash, a large estuary and important ecological area on the east coast of England. The Wash supports diverse aquatic life, including migratory fish and bird populations. The treatment plant helps reduce nutrient and pollutant loads to protect this sensitive downstream environment.
