Overview
Sunching wastewater treatment plant in Mötzing, Bayern, Germany, serves 2,310 people with advanced treatment and a designed capacity of 5,000 m³/day.
Sunching is a wastewater treatment plant located in Mötzing, a municipality in the Landkreis Regensburg, Bayern, Germany. The plant serves a population of 2,310 and has a designed capacity of 5,000 cubic meters per day, with an average discharge volume of 782.9 m³/day. It is classified as an advanced treatment facility, indicating a high level of pollutant removal. As a German plant, Sunching operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The advanced treatment level suggests the plant likely employs tertiary processes such as nutrient removal or disinfection, meeting stringent standards for sensitive areas. The plant's capacity utilization is moderate, reflecting typical operational patterns for a small community. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, which flows into the Black Sea. The plant plays a key role in protecting the region's aquatic ecosystems, particularly the Danube's tributaries, from nutrient pollution and organic load. Its advanced treatment helps maintain water quality in a region known for its agricultural and ecological significance.
Environmental context
The plant discharges into the Danube River basin, which flows southeast through Germany, Austria, and several other countries before reaching the Black Sea. The Danube supports diverse aquatic life, including migratory fish species such as sturgeon, and is a critical water resource for millions of people. The advanced treatment at Sunching reduces nutrient loads, helping to prevent eutrophication in downstream lakes and the Black Sea.
