Overview
Great Yarmouth Caister STW serves over 108,000 people in Norfolk, England. The plant discharges treated wastewater into the North Sea via the Yare estuary, supporting local water quality.
Great Yarmouth Caister STW is a major wastewater treatment facility located in Newtown, Great Yarmouth, Norfolk, England. Serving a population of approximately 108,084, it is a key component of the region's wastewater infrastructure, managing sewage from the coastal town and surrounding areas. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is expected to provide at least secondary treatment, with tertiary treatment required if discharging into sensitive areas. The plant's designed capacity is 1.00 (likely in megaliters per day or similar unit), indicating it is sized to handle the local population's wastewater. The treated effluent is discharged into the North Sea via the Yare estuary, a dynamic coastal environment that supports diverse aquatic life and important migratory bird populations. The plant plays a crucial role in protecting the ecological health of the Broads National Park and the wider Norfolk coastline.
