Mieste Wastewater Treatment Plant, Gardelegen | Advanced Treatment in Saxony-Anhalt

The Mieste wastewater treatment plant is located in the Hopfenhorst area of Mieste, a district of Gardelegen in Saxony-Anhalt, Germany. It serves a population of 5,375 and is designed to handle a capacity of 10,000 m³ per day, with an average discharge volume of 462.53 m³ per day. As an advanced treatment facility, it goes beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant's advanced processes ensure high-quality effluent, reducing nutrients and pollutants to protect receiving waters. The plant discharges into local watercourses that drain into the Elbe River basin, ultimately reaching the North Sea. Its advanced treatment helps maintain water quality in the sensitive riverine ecosystems of Saxony-Anhalt, supporting aquatic life and downstream uses.

The plant's effluent enters small streams in the Altmark region, which flow into the Ohre River, a tributary of the Elbe. The Elbe River is a major European waterway that supports diverse aquatic habitats and is an important migratory corridor for fish. The advanced treatment at Mieste helps reduce nutrient loading, protecting the Elbe's ecological health and its downstream estuary in the North Sea.
