Overview
Depuratore di Pozza di Fassa is a municipal wastewater treatment plant serving San Giovanni di Fassa in Trentino-Alto Adige, Italy. It treats wastewater from approximately 21,097 people in the Fassa Valley.
Depuratore di Pozza di Fassa is a wastewater treatment plant located in San Giovanni di Fassa (Sèn Jan), within the Trentino-Alto Adige region of northern Italy. The plant serves the local population of about 21,097 residents in the scenic Fassa Valley, a popular Alpine destination. As part of Italy's municipal wastewater infrastructure, it plays a key role in protecting the region's pristine mountain environment. The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size (between 10,000 and 150,000 population equivalent). The directive mandates that discharges into sensitive areas receive more advanced treatment. Given the Alpine setting, the plant likely employs biological treatment to meet stringent effluent standards. The treated effluent is discharged into local watercourses that ultimately feed into the Avisio River, a tributary of the Adige River. The Adige flows south through Trentino and Veneto before entering the Adriatic Sea near Chioggia. The plant's operation is critical for maintaining water quality in the Fassa Valley, which supports tourism, agriculture, and sensitive aquatic ecosystems.
Environmental context
The plant discharges into the Avisio River basin, which flows into the Adige River, one of Italy's major rivers. The Adige drains into the Adriatic Sea, supporting diverse aquatic life and important migratory fish species. The surrounding Dolomites region is ecologically sensitive, with pristine streams and alpine habitats that require high water quality standards to sustain biodiversity and recreational use.
Frequently asked questions
The plant is located in San Giovanni di Fassa (Sèn Jan), in the Trentino-Alto Adige region of northern Italy, within the Fassa Valley.
The plant serves approximately 21,097 people, making it a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive.
Treated effluent is discharged into local streams that flow into the Avisio River, a tributary of the Adige River, which ultimately reaches the Adriatic Sea.
The plant operates under Italy's transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size and may require tertiary treatment if the receiving waters are sensitive.
For agglomerations between 10,000 and 150,000 population equivalent, the EU directive requires secondary treatment (biological treatment). In sensitive Alpine areas, additional nutrient removal may be necessary to protect water quality.
