ZV Chiemsee Wastewater Treatment Plant, Rosenheim, Bavaria

ZV Chiemsee is a municipal wastewater treatment plant located in Rosenheim, Bavaria, Germany. It serves a population of approximately 65,525, classifying it as a medium-to-large agglomeration under EU regulations. The plant is situated near the Chiemsee lake region, a significant ecological area in southern Germany. As a German facility serving over 50,000 people, ZV Chiemsee is required to meet stringent treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive mandates at least secondary treatment, with tertiary treatment required if the receiving waters are designated as sensitive areas. It is expected to comply with these regulatory requirements. The treated effluent from ZV Chiemsee likely discharges into the Inn River or a tributary, which flows into the Danube and ultimately the Black Sea. The plant plays a crucial role in protecting the water quality of the Chiemsee region, a popular recreational area and important habitat for aquatic life. Its operation helps prevent nutrient pollution and supports the ecological health of the downstream watershed.

The plant is located in the Chiemsee region, a lake district in Bavaria. Treated wastewater likely flows into the Inn River, a major tributary of the Danube, which drains into the Black Sea. The area supports diverse aquatic ecosystems and is important for migratory fish species. Protecting water quality here is essential for maintaining the ecological balance of the downstream river system.
