Pettstadt Wastewater Treatment Plant, Neuhaus, Bavaria | Closed Secondary Facility

The Pettstadt wastewater treatment plant is located in Neuhaus, a district of Pettstadt in the Landkreis Bamberg, Bavaria, Germany. It served a population of 1,454 people before its closure. The plant is situated inland, away from coastal areas, and its operations were part of the regional wastewater infrastructure in the Regnitz river basin. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity was 3,000 m³/day, and the actual discharge volume was 623.36 m³/day, indicating the plant operated well below its capacity. As a closed facility, it no longer processes wastewater. The treated effluent was discharged into local water bodies that ultimately drain into the Regnitz River, a tributary of the Main, which flows into the Rhine. The Rhine basin supports diverse aquatic ecosystems and is a major European waterway. The plant's closure may have been due to consolidation with larger nearby facilities, a common practice in the region to improve efficiency and meet stricter environmental standards.

The plant discharged into the Regnitz River basin, part of the larger Rhine watershed. The Regnitz flows through the Bamberg region and joins the Main, which eventually reaches the North Sea. The area supports diverse aquatic life, including fish species such as barbel and chub. The plant's secondary treatment helped reduce organic pollutants, protecting downstream water quality in this ecologically sensitive river system.
