Pahlen_Dorpling Wastewater Treatment Plant, Pahlen, Schleswig-Holstein

Pahlen_Dorpling is a wastewater treatment plant located in Pahlen, a municipality in the district of Dithmarschen, Schleswig-Holstein, Germany. The plant served a population of approximately 1,787 people and was designed with a capacity of 2,320 cubic meters per day, though its current operational status is closed. As a secondary treatment facility, the plant met the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. For populations between 2,000 and 10,000, secondary treatment is the baseline requirement, and the plant's design capacity suggests it was sized appropriately for its service area. The plant discharged treated wastewater into the local water system, likely the Eider River, which flows through the region and eventually drains into the North Sea. The Eider is an important watercourse in Schleswig-Holstein, supporting diverse aquatic life and contributing to the ecological health of the Wadden Sea area.

The plant's treated effluent entered the Eider River, a major river in Schleswig-Holstein that flows through the Eider-Treene-Sorge lowlands before reaching the North Sea. This region is ecologically sensitive, supporting migratory fish species and providing habitat for waterbirds. The downstream environment includes tidal marshes and mudflats that are part of a larger coastal ecosystem.
