Overview
DP09703001_DERVIO is a municipal wastewater treatment plant in Dervio, Lombardy, Italy, serving approximately 5,974 people. It discharges into the local water system near Lake Como.
DP09703001_DERVIO is a municipal wastewater treatment plant located in Dervio, a town on the eastern shore of Lake Como in the Lombardy region of Italy. The plant serves a population of approximately 5,974 residents, placing it in the small-to-medium agglomeration category under Italian and EU regulations. Its location along the lakeside makes it a key facility for protecting the water quality of Lake Como, a major tourist and ecological asset. As an Italian plant serving fewer than 10,000 people, DP09703001_DERVIO is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for discharges into freshwater bodies like Lake Como. Plants of this scale typically employ biological treatment systems to meet the directive's standards. Its operational status and compliance with regional environmental permits ensure it functions within regulatory limits. The plant's treated effluent is discharged into the Lake Como watershed, which drains into the Adda River and eventually into the Po River and the Adriatic Sea. Lake Como is a deep, oligotrophic lake that supports diverse aquatic life and is a critical water resource for the region. The plant's role in removing nutrients and pollutants helps prevent eutrophication and maintains the lake's ecological health, which is vital for local biodiversity, tourism, and downstream water quality.
Environmental context
The plant discharges into the Lake Como basin, a deep subalpine lake that flows into the Adda River, a tributary of the Po River, which empties into the Adriatic Sea. Lake Como is an ecologically sensitive water body with low nutrient levels, making it vulnerable to eutrophication from nutrient inputs. The plant's treatment helps protect the lake's water quality, supporting diverse aquatic species and recreational uses. Downstream, the Adda and Po rivers sustain extensive agricultural and wetland ecosystems before reaching the Adriatic.
