Overview
Landquart wastewater treatment plant serves Igis in Graubünden, Switzerland, treating wastewater for approximately 19,088 people. The plant operates under Swiss water protection regulations.
The Landquart wastewater treatment plant is located in Igis, within the Landquart municipality in the canton of Graubünden, Switzerland. It serves a population of approximately 19,088 people, placing it in the medium agglomeration category under Swiss wastewater management standards. Switzerland enforces stringent water protection laws under the Federal Water Protection Act (GSchG), which mandates advanced treatment for all wastewater before discharge. For plants of this scale, secondary treatment with nutrient removal is typically required to protect sensitive alpine and pre-alpine water bodies. The plant discharges into the local hydrological network, which ultimately drains into the Rhine River via the Landquart River. The Rhine is a major European waterway that flows into the North Sea, supporting diverse aquatic ecosystems and serving as a critical water resource for multiple countries.
Environmental context
The Landquart plant treats wastewater in the Rhine basin, with effluent likely entering the Landquart River, a tributary of the Alpine Rhine. The Rhine flows through Switzerland, Germany, and the Netherlands before reaching the North Sea. This watershed supports diverse aquatic life, including migratory fish species, and is ecologically sensitive due to its alpine origins and downstream importance for water quality.
