NEWTOWN ST BOSWELL WWTW - Advanced Wastewater Treatment in Newtown St Boswells, Scottish Borders

NEWTOWN ST BOSWELL WWTW is located in Newtown St Boswells, a village in the Scottish Borders region of Scotland. The plant serves a population equivalent of 1,994, classifying it as a small agglomeration under Scottish water regulations. It is situated inland, more than 10 km from the coast, and discharges treated wastewater into the local river system. The plant employs advanced treatment processes, which go beyond the minimum secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The designed capacity of 2,424 m³/day indicates the plant has headroom for future growth, while current discharge volume is 443.93 m³/day. The treated effluent flows into the River Tweed catchment, a major river system in the Scottish Borders that drains into the North Sea. The Tweed is renowned for its salmon fishing and supports diverse aquatic life. The advanced treatment helps maintain water quality in this ecologically sensitive river, which is designated as a Site of Special Scientific Interest (SSSI) for its conservation value.

The plant discharges into the River Tweed catchment, which flows eastward through the Scottish Borders and enters the North Sea near Berwick-upon-Tweed. The Tweed is a high-quality salmon river and supports a rich ecosystem, including otters, lampreys, and freshwater pearl mussels. Advanced treatment at this plant helps control nutrient inputs, protecting the river from eutrophication and preserving its ecological status.
