Overview
HENDON STW serves approximately 222,784 people in Sunderland, England, discharging treated wastewater into the North Sea via Roker Marina. The plant operates under the UK's implementation of the EU Urban Waste Water Treatment Directive.
HENDON STW is a major wastewater treatment facility located in Sunderland, North East England, serving a population of around 222,784. Situated at Roker Marina, the plant is part of the region's critical water infrastructure, managing sewage from a densely populated urban area. As a large agglomeration serving over 150,000 people, HENDON STW is required to meet stringent treatment standards under the UK's transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). This typically mandates secondary treatment as a minimum, with tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in megalitres per day or similar unit), indicating a substantial facility. The plant discharges treated effluent into the North Sea via Roker Marina, a coastal outfall. This marine environment supports diverse aquatic life and is an important area for migratory fish and seabirds. The discharge is regulated to protect coastal water quality and comply with environmental standards.
Environmental context
HENDON STW discharges into the North Sea through Roker Marina, a coastal environment that supports diverse marine ecosystems, including fish populations and seabird colonies. The North Sea is a productive water body that receives inputs from multiple rivers and urban centers, making careful management of nutrient and pollutant loads essential to prevent eutrophication and maintain water quality. The plant's location within 50 km of the coast underscores the importance of its treatment processes in safeguarding the marine environment.
