Neckertal Tufi is a municipal wastewater treatment plant located in the Toggenburg region of St. Gallen, Switzerland. Serving a population of about 1,646, the plant is part of the country's decentralized wastewater infrastructure for smaller agglomerations. The plant provides secondary treatment, which is the standard biological treatment required under Swiss regulations for communities of this size. With a designed capacity of 2,750 m³/day and an actual discharge volume of 747.16 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local river system, which ultimately drains into the Rhine River basin. The plant plays a key role in protecting the water quality of the region's streams and the downstream Rhine ecosystem, supporting aquatic life and recreational uses.
