HUNDWILBOEMMELI is a wastewater treatment plant located in the village of Hundwil, within the canton of Appenzell Ausserrhoden, Switzerland. The plant serves a small population of 93 residents, reflecting the rural character of the area. It is situated in the pre-Alpine region of eastern Switzerland, where small-scale treatment facilities are common. The plant provides secondary treatment, which is the standard biological treatment required under Swiss water protection regulations. Swiss law mandates that all wastewater receive at least secondary treatment before discharge, with more advanced treatment required in sensitive areas. The plant has a designed capacity of 217 cubic meters per day, with an average daily discharge volume of 42.22 cubic meters, indicating it operates well below its capacity. The treated effluent from HUNDWILBOEMMELI is discharged into a local watercourse that eventually drains into the Rhine River basin. The Rhine flows northward through Switzerland, Germany, and the Netherlands before reaching the North Sea. The plant's location in a rural, ecologically sensitive area means that proper treatment is essential to protect downstream aquatic habitats and water quality.
Environmental context
The plant discharges into a small stream that is part of the Rhine River basin. The Rhine is one of Europe's major rivers, supporting diverse aquatic life and providing drinking water for millions. The plant's secondary treatment helps protect the local watershed from nutrient pollution, which is critical in the pre-Alpine region where streams are often ecologically sensitive and support fish populations.
