SPELDHURST STW - Secondary Wastewater Treatment Plant in Tunbridge Wells, England

SPELDHURST STW is a municipal wastewater treatment plant located in Speldhurst, near Tunbridge Wells in Kent, England. The facility serves a population of approximately 3,219 people and has a designed capacity of 3,231 cubic meters per day, with an average discharge volume of 716.66 cubic meters per day. It operates under the regulatory framework of the UK Environment Agency, which enforces the Urban Waste Water Treatment Directive (91/271/EEC) for secondary treatment standards. The plant provides secondary treatment, which is the standard required for inland freshwater discharges under the EU UWWTD. For agglomerations of this size (3,000-10,000 population equivalent), secondary treatment is mandatory to reduce organic matter and suspended solids. The plant's discharge is regulated through a permit issued by the Environment Agency, ensuring compliance with water quality objectives for the receiving water body. The treated effluent from SPELDHURST STW is discharged into a local stream that flows into the River Medway, eventually reaching the Thames Estuary and the North Sea. The Medway catchment supports diverse aquatic life, including salmonid fisheries in its upper reaches, and is an important ecological corridor in southeast England. The plant's operation helps protect water quality in this sensitive river system.

The plant discharges into a tributary of the River Medway, which flows through the Kent countryside to the Thames Estuary and the North Sea. The Medway catchment supports a variety of habitats, including chalk streams and wetlands that are home to species such as the European eel and brown trout. Protecting water quality in this system is critical for maintaining biodiversity and recreational uses like fishing and boating.
