Horsmonden Tonbridge Kent STW - Wastewater Treatment Plant in Tunbridge Wells, Kent

Horsmonden Tonbridge Kent STW is a wastewater treatment plant located near Goudhurst in Tunbridge Wells, Kent, England. It serves a population of around 7,086 people, placing it in the small-to-medium agglomeration category under UK regulatory frameworks. However, as a facility serving fewer than 10,000 people, it is subject to the UK's implementation of the EU Urban Waste Water Treatment Directive, which requires appropriate treatment to protect the receiving environment. The designed capacity is noted as 1.00, though the unit is unspecified. The plant discharges treated effluent into local watercourses that ultimately drain into the River Medway catchment and then into the Thames Estuary. This area supports diverse aquatic life and is important for regional water quality management.

The plant's treated effluent flows into the River Medway catchment, which drains into the Thames Estuary and the North Sea. The local watershed supports a mix of rural and semi-urban land uses, with the River Medway providing habitat for fish and invertebrates. Downstream, the Thames Estuary is a major ecological and economic resource, requiring careful management of nutrient and pollutant loads.
