BIASCA Wastewater Treatment Plant, Biasca, Ticino, Switzerland

The BIASCA wastewater treatment plant is located in Biasca, a town in the Riviera district of Ticino, Switzerland. Serving a population of approximately 19,287, the plant is part of the municipal wastewater infrastructure for the region. The facility treats wastewater from residential and commercial sources, contributing to the protection of local water resources. As a Swiss treatment plant, BIASCA operates under the Federal Water Protection Act (Gewässerschutzgesetz), which mandates appropriate treatment levels based on the sensitivity of receiving waters. For agglomerations of this size, secondary treatment with nutrient removal is typically required to meet stringent effluent standards. The plant's design and operation align with these national regulations, ensuring effective pollutant removal. The treated effluent from BIASCA is discharged into the Ticino River, which flows through the canton of Ticino before joining the Po River in Italy and eventually reaching the Adriatic Sea. The plant plays a key role in maintaining the water quality of the Ticino River, which supports diverse aquatic life and is used for recreation and irrigation downstream.

The BIASCA plant discharges into the Ticino River, a major tributary of the Po River basin. The Ticino River flows south through Switzerland and Italy, supporting ecosystems including fish populations and riparian habitats. Downstream, the river contributes to the Po River delta, an ecologically sensitive area that supports migratory birds and aquatic biodiversity. The plant's treatment helps reduce nutrient loads and pollutants that could impact these downstream environments.
