Overview
REHETOBELHABSET is a secondary treatment plant in Rehetobel, Appenzell Ausserrhoden, Switzerland, serving 107 people. It discharges 48.57 units of treated wastewater and is located within 10 km of the coast.
REHETOBELHABSET is a wastewater treatment plant located in Rehetobel, a municipality in the canton of Appenzell Ausserrhoden, Switzerland. The plant serves a small population of 107 people, reflecting its role in a rural or peri-urban setting. It is situated near St. Gallerstrasse in the Vorderland region. The plant provides secondary treatment, which is the standard biological treatment required under Swiss water protection regulations. The plant operates well below its capacity, treating an average discharge volume of 48.57 units. Swiss wastewater treatment is governed by the Federal Water Protection Act (Gewässerschutzgesetz), which mandates appropriate treatment levels based on the sensitivity of receiving waters. The plant's proximity to the coast (within 10 km) means its treated effluent may eventually reach Lake Constance or the Rhine River system, which drains into the North Sea. This coastal influence underscores the importance of effective nutrient removal to protect downstream aquatic ecosystems and the broader marine environment.
Environmental context
The plant discharges into local watercourses that ultimately drain into the Rhine River basin, which flows into the North Sea. Given its coastal proximity, the treated effluent contributes to the nutrient load in downstream waters, potentially affecting algal growth and water quality in sensitive estuarine and marine habitats. The region supports diverse aquatic life, including migratory fish species, making consistent treatment performance critical for ecological health.
Frequently asked questions

The plant serves a small population of 107 people, typical for a rural community in the Vorderland region.
The plant discharges treated effluent into local watercourses that flow toward the Rhine River basin and eventually the North Sea. Its coastal proximity (within 10 km) means the discharge may influence nearshore water quality.
REHETOBELHABSET provides secondary treatment, which involves biological processes to remove organic matter and suspended solids. This meets the standard required under Swiss water protection laws for plants of this scale.
The plant operates under the Swiss Federal Water Protection Act (Gewässerschutzgesetz), which sets effluent quality standards and treatment requirements based on the sensitivity of receiving waters. For small agglomerations, secondary treatment is typically sufficient.
