ZV Reichenbachtal SButtenwiesen - Closed Wastewater Treatment Plant in Unterthürheim, Bavaria

ZV Reichenbachtal SButtenwiesen is a former wastewater treatment plant located in Unterthürheim, a district of Buttenwiesen in the Bavarian county of Dillingen an der Donau. The plant served a small population of around 1,780 people and was designed to handle a capacity of 4,800 cubic meters per day. It is now closed and no longer in operation. The plant provided secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Although the plant is closed, the regulatory framework in Germany ensures that wastewater from this area is now likely treated at a neighboring facility that meets the same directive requirements. The plant's discharge volume was recorded at 450.48 m³/day, and its operations would have impacted local water bodies in the Danube basin. The region is inland, far from coastal areas, and the treated effluent would have eventually drained into the Danube River, which flows into the Black Sea.

The plant is situated in the Danube River basin, with its treated effluent historically flowing into local streams that feed into the Danube. The Danube is a major European waterway that ultimately discharges into the Black Sea. The region supports diverse aquatic life and is part of a large transboundary river system. The closure of this plant likely reduces local discharge impacts, but the surrounding watershed remains sensitive to nutrient loading from agricultural and urban runoff.
