TETBURY STW - Wastewater Treatment Plant in Cotswold, Gloucestershire

TETBURY STW is a wastewater treatment plant located on Newnton Road, Long Newnton, in the Cotswold district of Gloucestershire, England. It serves a population of approximately 5,779 people, making it a small to medium-sized facility within the UK's wastewater infrastructure. As a plant in the United Kingdom, TETBURY STW operates under the Water Industry Act 1991 and is regulated by the Environment Agency. For agglomerations of this scale, UK regulations typically require secondary treatment as a minimum, with additional nutrient removal if discharging into sensitive areas. The treated effluent from TETBURY STW is discharged into a local watercourse, which ultimately flows into the River Avon or River Thames catchment, depending on the exact receiving water body. This area supports diverse aquatic life and is part of the broader Severn Estuary or Thames Basin ecosystem, both of which are ecologically important for migratory fish and bird species.

TETBURY STW discharges into a local stream that feeds into the River Avon or River Thames system, eventually reaching the Severn Estuary or the North Sea. The Cotswold region is characterized by limestone geology and groundwater-dependent ecosystems. The receiving waters support aquatic habitats and are part of a catchment that provides drinking water and recreational opportunities. Nutrient management is important to prevent eutrophication in downstream water bodies.
