Billigheim Wastewater Treatment Plant: Serving Billigheim, Rhineland-Palatinate

The Billigheim wastewater treatment plant is located in the town of Billigheim, within the Landau-Land district of Rhineland-Palatinate, Germany. It serves a population of approximately 16,635 residents, classifying it as a medium-sized agglomeration under European Union regulations. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and EU water quality goals. The treated effluent from the Billigheim plant is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway that flows through Germany and the Netherlands before reaching the North Sea. The plant plays a key role in protecting the water quality of the Rhine basin, which supports diverse aquatic life and serves as a critical resource for drinking water, agriculture, and industry.

The Billigheim plant discharges into the local tributaries of the Rhine River, which flows through Germany and the Netherlands into the North Sea. The Rhine basin is ecologically significant, supporting a variety of fish species and migratory birds. The plant's operations help maintain water quality in this important watershed, reducing nutrient and pollutant loads that could otherwise impact downstream ecosystems.
