Mengerskirchen Dillhausen Wastewater Treatment Plant, Dillhausen, Hessen

The Mengerskirchen Dillhausen wastewater treatment plant is located in Dillhausen, a district of Mengerskirchen in Hessen, Germany. It served a small population of 668 people before its closure. The plant is situated in the rural Lahn-Dill region, characterized by rolling hills and the Dill river valley. As a closed facility, the plant no longer treats wastewater. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this one (under 2,000 population equivalent) are subject to appropriate treatment requirements. The area drains into the Dill river, a tributary of the Lahn, which flows into the Rhine. The Rhine is a major European waterway and ecologically significant river, supporting diverse aquatic life and serving as a migratory corridor for fish species.

The plant is located in the Dill river watershed, which flows into the Lahn river and eventually the Rhine. The Rhine is a major European river that supports diverse aquatic ecosystems and is an important migratory corridor for fish such as salmon and eel. The closure of this small plant likely reduces local nutrient and pollutant loads to the Dill river, benefiting downstream water quality.
