Overview
LANGPORT STW serves Huish Episcopi, Somerset, England, treating wastewater for approximately 8,639 people. The plant operates under UK regulations implementing the EU Urban Waste Water Treatment Directive.
LANGPORT STW is a wastewater treatment plant located in Huish Episcopi, Somerset, England, serving a population of around 8,639. The facility is situated inland, more than 50 km from the coast, and discharges into local watercourses that ultimately drain to the Bristol Channel. As a plant serving a medium agglomeration (between 2,000 and 10,000 people), it is subject to the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater. The designed capacity is 1.00 (likely in megaliters per day or similar unit), indicating a facility sized for its catchment. The treated effluent enters the local river system, which flows through the Somerset Levels and Moors, an ecologically important wetland area. The downstream environment supports diverse aquatic life and is a key part of the region's natural flood management and biodiversity.
Environmental context
The plant discharges into the River Parrett catchment, which flows through the Somerset Levels and Moors before reaching the Bristol Channel. This area is a low-lying wetland of international importance for birdlife and aquatic habitats. The river system supports migratory fish species and provides critical floodplain storage. Downstream, the estuary mixes with the Severn Estuary, one of the largest tidal ranges in the world, influencing sediment and nutrient dynamics.
