BUCHBACH Wastewater Treatment Plant, Buchbach, Bayern, Germany

The BUCHBACH wastewater treatment plant is located in Buchbach, a municipality in the Landkreis Mühldorf am Inn district of Bayern, Germany. It serves a population of approximately 2,147 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated inland, far from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 4,000 m³/day and an average daily discharge of 543.35 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The advanced treatment level likely includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Inn River, a major tributary of the Danube. The Danube River Basin is one of Europe's most significant hydrological systems, supporting diverse aquatic ecosystems and providing water for millions of people. The plant's advanced treatment helps maintain water quality in this ecologically important basin.

The BUCHBACH plant discharges treated wastewater into local streams that flow into the Inn River, a major tributary of the Danube River. The Danube Basin supports a wide range of aquatic life, including fish species such as sturgeon and salmon, and is an important migratory corridor for birds. The advanced treatment at this plant helps reduce nutrient loads, protecting downstream ecosystems from eutrophication and maintaining the ecological health of the Inn and Danube rivers.
