UNTERSCHLATT_SCHLATT Wastewater Treatment Plant, Schlatt (TG), Thurgau

UNTERSCHLATT_SCHLATT is a municipal wastewater treatment plant located in Schlatt (TG), within the canton of Thurgau, Switzerland. The plant serves a population of approximately 1,307 residents, classifying it as a small agglomeration under Swiss water management standards. The facility provides secondary treatment, which is the standard biological treatment required for most Swiss plants under national regulations aligned with the EU Urban Waste Water Treatment Directive. With a designed capacity of 2,183 m³/day and an actual discharge volume of 593.28 m³/day, the plant operates well below its capacity, indicating reserve for future growth or seasonal variations. The treated effluent is discharged into the local water system, which ultimately drains into the Rhine River basin. The Rhine is a major European waterway that flows through Switzerland, Germany, and the Netherlands before reaching the North Sea. The plant's operation helps protect downstream aquatic ecosystems and drinking water sources in the region.

The plant discharges into a tributary of the Rhine River, which flows through the Swiss Plateau and into the North Sea. The Rhine basin supports diverse aquatic life, including salmonids and other sensitive species. The plant's secondary treatment reduces organic pollutants and suspended solids, helping maintain water quality in this ecologically important river system.
