PEGSWOOD STW - Secondary Wastewater Treatment in Pegswood, Northumberland

PEGSWOOD STW (Sewage Treatment Works) serves the village of Pegswood in Northumberland, North East England. The plant provides secondary treatment for a population equivalent of roughly 3,225, with a designed capacity of 3,357 m³/day and an average daily discharge of 718 m³/day. As a secondary treatment facility in the United Kingdom, PEGSWOOD STW operates under the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. For agglomerations of this size (under 10,000 population equivalent), secondary treatment is the standard requirement, ensuring effective removal of organic matter and suspended solids. The treated effluent from PEGSWOOD STW ultimately discharges into the North Sea via local watercourses. The plant's coastal location means its discharge contributes to the nutrient and pollutant load entering the marine environment, which is subject to the UK Marine Strategy and Water Framework Directive objectives for good ecological status.

The plant's discharge enters local streams that flow into the River Wansbeck, which reaches the North Sea at Cambois Bay. The Northumberland coast is ecologically sensitive, supporting diverse marine life including seabird colonies and coastal fish populations. The Wansbeck estuary provides important habitat for migratory birds and juvenile fish, making nutrient management from wastewater discharges critical to maintaining water quality and ecosystem health.
