4550202013 KA Hooksiel is an advanced wastewater treatment plant located in the Hooksiel district of Wangerland, in the Landkreis Friesland region of Niedersachsen, Germany. The plant serves a population of 7,785 and has a designed capacity of 13,500 m³/day, with an actual discharge volume of 763.98 m³/day. As an advanced treatment facility, KA Hooksiel provides a higher level of treatment beyond secondary, likely including nutrient removal or disinfection. This aligns with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and agglomerations of this scale in Germany. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the North Sea. The coastal location near the Wadden Sea, a UNESCO World Heritage site, underscores the importance of advanced treatment to protect this ecologically sensitive marine environment. The plant plays a key role in safeguarding water quality in the region.

The plant discharges into the local drainage network that flows into the North Sea via the Jade Bight. The Wadden Sea, a large intertidal ecosystem, supports diverse aquatic life including migratory birds and marine species. Advanced treatment helps minimize nutrient loading and protect this sensitive coastal environment.
