Overview
HINWIL wastewater treatment plant serves the town of Hinwil in the canton of Zürich, Switzerland. It treats wastewater from a population of approximately 12,165 people.
The HINWIL wastewater treatment plant is located in Hinwil, a town in the Bezirk Hinwil district of the canton of Zürich, Switzerland. The plant serves a population of about 12,165 residents, making it a medium-sized facility within the Swiss wastewater infrastructure. Switzerland's wastewater treatment is governed by the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment for all plants to protect sensitive water bodies. For agglomerations of this scale, secondary treatment with nutrient removal is standard, ensuring compliance with stringent national standards. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Rhine River basin, which flows through Switzerland, Germany, and the Netherlands before reaching the North Sea. This downstream connection underscores the plant's role in protecting the broader Rhine ecosystem.
Environmental context

The Rhine supports diverse aquatic life and is an important migratory corridor for fish. Downstream, the river flows through densely populated and industrial areas, making effective wastewater treatment critical for maintaining water quality and ecological health.
