Overview
STANSROTZWINKEL wastewater treatment plant serves Stans, Nidwalden, Switzerland, treating wastewater for approximately 37,333 people. It is located inland, with discharge likely to local water bodies.
STANSROTZWINKEL is a wastewater treatment plant located in Stans, within the canton of Nidwalden, Switzerland. The facility serves a population of approximately 37,333, placing it in the medium agglomeration category under Swiss and EU regulatory frameworks. As part of Switzerland's wastewater infrastructure, the plant plays a key role in protecting local water quality. The plant operates under Swiss water protection regulations, which align with the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Such regulations typically require secondary treatment as a minimum, with tertiary treatment in sensitive areas. The plant is expected to meet these standards to ensure effective pollutant removal. The treated effluent is discharged into local water bodies that eventually drain into the Reuss River and then the Rhine River, which flows to the North Sea. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall water quality of the Rhine basin, supporting aquatic ecosystems and downstream communities.
Environmental context
The plant's discharge enters the local watershed, which drains into the Reuss River and subsequently the Rhine River, one of Europe's major waterways. The Rhine basin supports diverse aquatic life and is an important ecological corridor. The plant's treatment performance is critical for maintaining water quality in this sensitive river system, particularly given the population served and the potential for nutrient loading.
