Overview
DP01400501_ARDENNO is a wastewater treatment plant serving Sirta, Lombardia, Italy. It handles a population of approximately 18,317 and operates under the EU Urban Waste Water Treatment Directive.
DP01400501_ARDENNO is a wastewater treatment plant located in Sirta, within the Lombardia region of northern Italy. The facility serves a population of around 18,317, classifying it as a medium-sized agglomeration under European Union standards. Situated in the Valtellina valley near the Adda River, the plant plays a key role in managing municipal wastewater for this Alpine community. As an Italian plant, DP01400501_ARDENNO operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. Italy implements this directive through national regulations enforced by regional environmental agencies. The plant's treatment processes are designed to meet the required effluent standards for inland freshwater bodies, ensuring compliance with both Italian and EU water quality objectives. The treated effluent from DP01400501_ARDENNO is discharged into the local watershed, which ultimately drains into the Adda River. The Adda flows through the Valtellina valley into Lake Como, a major subalpine lake, and then continues to the Po River, which empties into the Adriatic Sea. This downstream chain highlights the plant's importance in protecting the ecological health of Lake Como and the Po River basin, supporting aquatic life and water quality for downstream communities.
Environmental context
The plant discharges into the Adda River, which flows through the Valtellina valley into Lake Como, a deep subalpine lake with significant ecological value. Lake Como supports diverse aquatic species and is a critical water resource for the region. The Adda then joins the Po River, which drains into the Adriatic Sea. The plant's operations help maintain water quality in this sensitive Alpine-to-sea corridor, protecting habitats and recreational uses.

The plant serves a population of approximately 18,317 people, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent is discharged into the local watershed, which flows into the Adda River. The Adda River runs through the Valtellina valley into Lake Como and eventually reaches the Po River and the Adriatic Sea.
As an Italian wastewater treatment plant, DP01400501_ARDENNO operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Compliance is enforced by regional environmental agencies in Lombardia.
For agglomerations of this scale (10,000-50,000 population equivalent), the EU Urban Waste Water Treatment Directive mandates secondary treatment as a minimum. In sensitive areas, such as those draining into Lake Como, tertiary treatment may be required to reduce nutrients and protect water quality.
