Klaranlage Buttisholz - Wastewater Treatment Plant in Buttisholz, Luzern, Switzerland

Klaranlage Buttisholz is a municipal wastewater treatment plant located in Buttisholz, a town in the canton of Luzern, Switzerland. The plant serves a population of about 2,842 residents, making it a small-scale facility within the Swiss wastewater infrastructure. As a Swiss plant, it operates under the national Water Protection Act (Gewässerschutzgesetz), which mandates stringent treatment standards to protect water resources. For small agglomerations like Buttisholz, secondary treatment with nutrient removal is typically required to meet the high environmental standards set by Swiss regulations. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Reuss River, a tributary of the Aare River, which flows into the Rhine. The Rhine ultimately reaches the North Sea, making the plant's operations important for downstream water quality in this major European basin.

The plant discharges into small streams in the Buttisholz area, which feed into the Surental region's water network and eventually the Reuss River. The Reuss flows through central Switzerland, joining the Aare and then the Rhine, which drains into the North Sea. The local watershed supports diverse aquatic life and is part of Switzerland's efforts to maintain high water quality standards under the Water Protection Act.
