HESSDORF OT HANNBERG Wastewater Treatment Plant, Hannberg, Bavaria

HESSDORF OT HANNBERG is a former wastewater treatment plant located in Hannberg, a district of Heßdorf in Bavaria, Germany. The plant served a population of 1,907 and was classified as a secondary treatment facility. It is now closed, but its operational history reflects the local approach to wastewater management in the Erlangen-Höchstadt district. As a secondary treatment plant, HESSDORF OT HANNBERG provided biological treatment to reduce organic matter and suspended solids. The plant had a designed capacity of 1,200 cubic meters per day and discharged an average of 482.62 cubic meters per day. German wastewater plants are regulated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's treated effluent was discharged into local water bodies that ultimately drain into the Regnitz River, a tributary of the Main River, which flows into the Rhine. The Rhine basin supports diverse aquatic life and is an important ecological corridor in Europe.

The plant's discharge entered local streams that flow into the Regnitz River, a key tributary of the Main River, which eventually joins the Rhine. The Rhine basin is a major European watershed supporting diverse fish species and migratory birds. The area is part of the Franconian region, characterized by agricultural and urban influences. Proper treatment helps protect downstream water quality and aquatic habitats.
