Overview
Immenhausen Holzhausen is a closed advanced treatment plant in Knickhagen, Hessen, Germany. It served 1,816 people with a designed capacity of 3,500 m³/day and discharged 459.59 m³/day.
Immenhausen Holzhausen wastewater treatment plant is located in Knickhagen, within the Fuldatal municipality in Hessen, Germany. The plant served a population of 1,816 and had a designed capacity of 3,500 cubic meters per day, with an average discharge volume of 459.59 cubic meters per day. It is now closed. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The plant's operational history reflects Germany's commitment to high treatment standards under national water law (Wasserhaushaltsgesetz). The treated effluent from the plant would have discharged into the Fulda River, a tributary of the Weser River, which flows to the North Sea. The Fulda River supports diverse aquatic life and is an important waterway in the region. The plant's advanced treatment helped protect the river's water quality and downstream ecosystems.
Environmental context
The plant discharged into the Fulda River, which flows north to join the Weser River and eventually reaches the North Sea. The Fulda River is a significant watercourse in Hessen, supporting fish populations and riparian habitats. Advanced treatment at this plant would have reduced nutrient loads, helping to prevent eutrophication in downstream waters. The surrounding area is characterized by mixed agricultural and forested land, with the river providing ecological connectivity.
