Overview
SKA RIED is a wastewater treatment plant serving Isny im Allgäu, Baden-Württemberg, Germany. It treats wastewater for approximately 32,350 people and has a designed capacity of 1.00 unit.
SKA RIED is a municipal wastewater treatment plant located in Unterried, near Isny im Allgäu in the district of Ravensburg, Baden-Württemberg, Germany. The plant serves a population equivalent of around 32,350, placing it in the medium agglomeration category under German and EU regulations. As a German plant, SKA RIED operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 unit, and it is expected to meet stringent effluent standards to protect local water bodies. The treated effluent from SKA RIED likely discharges into a tributary of the Rhine basin, given the location in the Allgäu region. The plant plays a key role in safeguarding the water quality of local streams and rivers that eventually drain into Lake Constance and the Rhine River, supporting aquatic ecosystems and downstream water uses.
Environmental context
The plant is situated in the Allgäu region, a headwater area for the Rhine basin. Treated wastewater likely flows into small streams that feed the Argen or other tributaries of Lake Constance (Bodensee). Lake Constance is a major drinking water reservoir and ecologically sensitive area, supporting diverse aquatic life and migratory birds. The plant's performance is critical to maintaining the lake's water quality and the ecological health of the Rhine downstream.
Frequently asked questions
SKA RIED is located in Unterried, near Isny im Allgäu, in the district of Ravensburg, Baden-Württemberg, Germany.
The plant serves approximately 32,350 people, classifying it as a medium-sized agglomeration under EU standards.
The treated effluent is discharged into local streams that are part of the Rhine basin, eventually reaching Lake Constance and the Rhine River.
As a German plant serving over 10,000 people, SKA RIED must comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment and, in sensitive areas, tertiary treatment to reduce nutrients.
In Germany, plants of this scale typically employ secondary biological treatment (e.g., activated sludge) and often include nutrient removal to meet strict German and EU effluent standards, especially in catchments draining to sensitive water bodies like Lake Constance.
