KA HANGARD Wastewater Treatment Plant, Hangard, Neunkirchen, Saarland

KA HANGARD is an advanced wastewater treatment plant located in the Hangard district of Neunkirchen, in the Saarland region of Germany. The plant serves a population of approximately 2,100 residents, making it a small-scale facility within the local municipal infrastructure. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,400 m³/day and an actual discharge volume of 595.50 m³/day, the plant operates well within its capacity, ensuring reliable treatment performance. The treated effluent is discharged into local watercourses that drain into the Blies River, a tributary of the Saar, which flows into the Moselle and ultimately the Rhine. This Rhine basin context underscores the plant's role in protecting downstream water quality in a densely populated and industrially active region of Europe.

KA HANGARD discharges into the local drainage network that feeds the Blies River, a tributary of the Saar. The Saar flows into the Moselle, which joins the Rhine, one of Europe's major rivers. The Rhine basin supports diverse aquatic life and is a critical migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient and pollutant loads, protecting the ecological health of these downstream water bodies.
