Overview
CREWE STW in Worleston, England serves approximately 98,000 people. The plant operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
CREWE STW is a wastewater treatment plant located in Worleston, Cheshire East, England, serving a population of around 98,000. The facility is situated inland, away from coastal areas, and plays a key role in managing municipal wastewater for the region. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent over 15,000 are required to provide secondary treatment, with more stringent tertiary treatment in sensitive areas. As a plant serving nearly 100,000 people, CREWE STW is expected to meet at least secondary treatment standards, ensuring effective removal of organic matter and nutrients. The treated effluent from CREWE STW is discharged into local watercourses that ultimately drain into the River Weaver and then the River Mersey estuary, which flows into the Irish Sea. This catchment supports diverse aquatic life and is important for regional water quality management.
Environmental context
