The Lengdorf wastewater treatment plant is located in Brandlengdorf, a district of Lengdorf in the Erding district of Bavaria, Germany. The facility serves a population of approximately 2,684 and operates with advanced treatment technology, ensuring high-quality effluent standards. With a designed capacity of 3,000 m³/day and an average discharge volume of 645.58 m³/day, the plant operates well below its capacity. As a German facility, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas and secondary treatment for all agglomerations above 2,000 population equivalents. The treated wastewater is discharged into local streams that eventually flow into the Isar River, a major tributary of the Danube. The Danube then drains into the Black Sea, making this plant part of a vast transboundary river basin that supports diverse aquatic ecosystems and multiple downstream communities.
Environmental context
The plant's effluent enters small watercourses in the Isar River basin, which flows through Munich and joins the Danube near Deggendorf. The Danube is a critical ecological corridor for fish migration and supports numerous species. The advanced treatment helps protect downstream water quality in the Danube Delta, a region of high ecological importance.
