Runding Wastewater Treatment Plant, Cham, Bavaria

Runding wastewater treatment plant is located in the Cham district of Bavaria, Germany, serving a small community of approximately 1,870 residents. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 3,000 m³/day indicates the plant was built to handle peak flows, though current discharge volume is reported at 473.25 m³/day. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Danube River basin, which flows into the Black Sea. The plant's operation helps protect the water quality of the receiving streams and downstream ecosystems, including the Danube's diverse aquatic habitats.

The plant discharges into small streams that feed into the Regen River, a tributary of the Danube. The Danube River basin is one of Europe's most important ecological corridors, supporting diverse fish species and migratory birds. The plant's secondary treatment reduces organic pollutants and nutrients, helping to maintain the ecological balance of the downstream waters.
