Overview
DP01403702_LIVIGNO is a wastewater treatment plant serving Livigno, Switzerland, with a population equivalent of 25,000. It operates under Swiss and EU regulatory frameworks for alpine wastewater management.
DP01403702_LIVIGNO is a wastewater treatment plant located in Livigno, in the Lombardia region of Switzerland. The plant serves a population equivalent of 25,000, placing it in the medium agglomeration category under the EU Urban Waste Water Treatment Directive (91/271/EEC), which applies to Swiss plants through bilateral agreements. The facility is situated in the alpine Valtellina valley, a region known for its mountainous terrain and tourism-driven population fluctuations. As a plant serving a medium-sized agglomeration, it is expected to provide at least secondary treatment under the EU UWWTD, with tertiary treatment required if discharging into sensitive areas. The alpine setting often necessitates advanced treatment to protect high-altitude water bodies. Typical facilities in this region employ biological treatment with nutrient removal to meet stringent Swiss water protection standards. The treated effluent from DP01403702_LIVIGNO discharges into the local watershed, which drains into the Adda River, a major tributary of the Po River. The Po River flows into the Adriatic Sea, making the plant part of a transboundary river basin. The alpine streams in this area support sensitive aquatic ecosystems, including cold-water fish species and unique macroinvertebrate communities. Protecting these waters is critical for maintaining biodiversity and water quality downstream.
Environmental context
The plant's receiving water body is part of the Adda River basin, which originates in the Alps and flows through Lake Como before joining the Po River. The Po River delta discharges into the Adriatic Sea, a semi-enclosed sea with eutrophication risks. The alpine watershed is ecologically sensitive, supporting species such as the marble trout and the yellow-bellied toad. Nutrient loading from wastewater can impact these fragile ecosystems, making advanced treatment important for preserving water quality in the region.
