REGENSDORFWUEERI Wastewater Treatment Plant, Regensdorf, Zürich

REGENSDORFWUEERI is a wastewater treatment plant located in Regensdorf, in the canton of Zürich, Switzerland. The facility serves a population of about 24,000 people, making it a medium-sized agglomeration within the Swiss wastewater management system. Switzerland enforces stringent water protection laws under the Federal Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment for plants serving over 10,000 people. Plants of this scale typically employ mechanical-biological treatment with nutrient removal to meet strict effluent standards for phosphorus and nitrogen, protecting sensitive receiving waters. The treated effluent from REGENSDORFWUEERI is discharged into local watercourses that flow into the Furtbach and eventually the Limmat River, which drains into the Rhine River and ultimately the North Sea. The plant plays a crucial role in safeguarding the water quality of these rivers and the downstream aquatic ecosystems.

The plant discharges into the local watershed of the Furtbach, a tributary of the Limmat River. The Limmat flows through Zürich and joins the Rhine, which is a major European waterway draining into the North Sea. This catchment supports diverse aquatic life and is important for regional biodiversity. The plant's advanced treatment helps maintain water quality in this ecologically sensitive river system.
