DARTMOUTH STW - South Hams, England Wastewater Treatment Plant

DARTMOUTH STW is a wastewater treatment plant located in South Hams, Devon, England, serving a population of around 10,504. The facility is situated near the River Dart estuary, a key coastal feature in the region. As a UK wastewater plant, it operates under the Urban Waste Water Treatment (England and Wales) Regulations, which transpose the EU Urban Waste Water Treatment Directive. And it treats wastewater from a medium-sized agglomeration. Under UK regulations, plants serving populations between 2,000 and 15,000 typically require secondary treatment, unless discharging into sensitive areas where more stringent standards apply. The regulatory framework ensures compliance with environmental standards. The treated effluent is discharged into the Dart Estuary, which flows into the English Channel. The estuary supports diverse aquatic life and is an important habitat for migratory birds and fish species. The plant's proximity to the coast (within 50 km) underscores the need for effective treatment to protect marine water quality and the broader ecosystem of the English Channel.

DARTMOUTH STW discharges into the Dart Estuary, a tidal inlet that flows into the English Channel. The estuary supports diverse aquatic life, including salmon and sea trout, and serves as a migratory corridor for birds. The plant's location near the coast means its effluent can influence coastal water quality, requiring treatment standards that protect the sensitive marine environment.
