Sandbach STW is a wastewater treatment plant located in Sandbach, Cheshire East, England. It serves a population of approximately 19,408 people, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its treated effluent likely discharges into local watercourses that feed into the River Wheelock or nearby tributaries. As a plant serving over 10,000 people, Sandbach STW is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. The regulatory framework ensures compliance with environmental standards. The plant's discharge ultimately reaches the River Wheelock, a tributary of the River Dane, which flows into the River Weaver and then the River Mersey estuary. This waterway supports diverse aquatic life and is part of the Mersey Basin, an important ecological and industrial region in northwestern England. The plant plays a key role in protecting local water quality and downstream habitats.
