PAULTON STW Wastewater Treatment Plant, Paulton, England

PAULTON STW is a wastewater treatment plant serving the village of Paulton in Bath and North East Somerset, England. Located in the West of England region, the facility provides essential sanitation for a population of around 10,000 residents. The plant is part of the UK's extensive wastewater infrastructure managed under the Water Industry Act 1991. As a secondary treatment plant under the Urban Waste Water Treatment Directive (transposed into UK law), PAULTON STW is expected to meet standards for biological oxygen demand and suspended solids. The designed capacity of 1.00 million litres per day indicates a facility sized for the local population. The plant's treatment process likely includes primary sedimentation followed by biological treatment, though specific process details are not publicly available. The treated effluent from PAULTON STW discharges into local rivers that drain into the Bristol Channel via the River Avon. The surrounding area includes agricultural land and small settlements, making the plant's performance important for maintaining water quality in the catchment. The plant contributes to protecting downstream ecosystems, including estuarine habitats in the Severn Estuary.

PAULTON STW discharges into the Cam Brook, a tributary of the River Avon, which flows into the Bristol Channel and the Severn Estuary. The estuary supports diverse aquatic life, including migratory fish species and important bird populations. The plant's location inland, over 50 km from the coast, reduces direct marine impact but requires careful management to prevent nutrient enrichment in the freshwater system.
