Ursensollen OT Hausen Heimhof Wastewater Treatment Plant, Hausen, Bavaria

Ursensollen OT Hausen Heimhof is a former wastewater treatment plant located in the Heimhof district of Hausen, within the municipality of Ursensollen in Bavaria, Germany. The plant served a small population of approximately 1,532 people and was designed with a capacity of 2,150 cubic meters per day. It is now closed and no longer in operation. As a secondary treatment facility, the plant would have provided biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to have appropriate treatment, typically secondary. However, this plant served fewer than 2,000 people, so it fell below the threshold for mandatory secondary treatment under the directive, though it still provided secondary treatment. The plant's discharge would have entered local watercourses in the Danube basin, as the region drains toward the Danube River. The closure of the plant suggests that wastewater from the area is now treated at a larger, more centralized facility, improving overall treatment efficiency and environmental protection.

The plant is located in the Bavarian region of Germany, within the Danube River basin. The nearest water bodies are small streams that eventually flow into the Danube, which drains into the Black Sea. The area is characterized by mixed agricultural and forested land, with sensitive aquatic ecosystems downstream. The closure of this plant likely reduces local nutrient and pollutant loads, benefiting the ecological health of the receiving waters.
