Taunton STW - Wastewater Treatment Plant in Creech St. Michael, Somerset

Taunton STW is a wastewater treatment plant located in Creech St. Michael, Somerset, England, serving a population of around 82,000. The plant is part of the UK's wastewater infrastructure, managed under the Water Industry Act and regulated by the Environment Agency. As a plant serving over 80,000 people, Taunton STW is classified as a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), which the UK has retained post-Brexit. This directive requires secondary treatment as a minimum, with tertiary treatment in sensitive areas. The plant's designed capacity is 1. The treated effluent from Taunton STW is discharged into the River Tone, a tributary of the River Parrett, which flows into the Bristol Channel. The River Tone supports diverse aquatic life and is used for recreation. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the Parrett catchment.

Taunton STW discharges into the River Tone, which flows into the River Parrett and then into the Bristol Channel. The River Tone is a lowland river that supports coarse fish populations and provides habitat for aquatic invertebrates. The Parrett catchment is agriculturally intensive, and nutrient management is a key concern to prevent eutrophication in the Bristol Channel.
