Weilheim_Ob Wastewater Treatment Plant, Weilheim in Oberbayern, Bavaria

Weilheim_Ob is a wastewater treatment plant located in Weilheim in Oberbayern, Bavaria, Germany. It serves a population of around 32,718 people, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are integral to local water management. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving populations between 10,000 and 100,000 are required to provide secondary treatment as a minimum. For sensitive areas, more stringent treatment may be mandated. It is expected to comply with these EU standards. The treated effluent from Weilheim_Ob is discharged into local water bodies that ultimately drain into the Danube River basin, which flows into the Black Sea. The plant plays a crucial role in protecting the water quality of the Ammer River and downstream ecosystems, supporting aquatic life and recreational uses.

The plant discharges into the Ammer River, a tributary of the Danube River basin. The Danube flows through multiple countries before reaching the Black Sea, making the plant's operations significant for transboundary water quality. The local watershed supports diverse aquatic habitats and is important for regional biodiversity. Proper treatment helps prevent nutrient pollution and protects downstream ecosystems.
