Overview
Depuratore di Riva Arena serves Riva del Garda, Italy, treating wastewater for approximately 38,650 people. The plant discharges into the local water system, supporting the environmental quality of Lake Garda.
Depuratore di Riva Arena is a municipal wastewater treatment plant located in Riva del Garda, in the Trentino-Alto Adige region of northern Italy. The facility serves a population of around 38,650, making it a medium-sized agglomeration under EU classification. Its location on the northern shore of Lake Garda places it in a sensitive alpine lake environment. As an Italian plant serving a population between 10,000 and 100,000, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. Given the sensitivity of Lake Garda, the plant likely provides tertiary treatment to protect water quality. The facility is part of the regional wastewater infrastructure managed by local authorities. The treated effluent is discharged into the Lake Garda basin, which drains into the Mincio River and eventually the Po River and the Adriatic Sea. Lake Garda is a major ecological and tourist resource, supporting diverse aquatic life and serving as a drinking water source. The plant plays a key role in preventing eutrophication and maintaining the lake's high water quality standards.
Environmental context
The plant discharges into the Lake Garda watershed, the largest lake in Italy, which flows into the Mincio River and then the Po River before reaching the Adriatic Sea. Lake Garda is a deep subalpine lake with high ecological sensitivity, supporting endemic fish species and extensive macrophyte beds. The region's tourism and agriculture depend on the lake's water quality, making advanced treatment essential to control nutrient loading and prevent algal blooms.
