DP01307501_COMO Wastewater Treatment Plant, Como, Lombardy, Italy

DP01307501_COMO is a wastewater treatment plant located in Como, in the Lombardy region of northern Italy. The plant serves a population of approximately 162,594, classifying it as a large agglomeration under EU regulations. Situated near the southwestern tip of Lake Como, the facility is part of the region's critical water infrastructure. As a large agglomeration, the plant is expected to provide at least secondary treatment under the EU Urban Waste Water Treatment Directive (91/271/EEC). Given the sensitivity of the receiving waters (Lake Como and downstream Po River basin), tertiary treatment may be required to reduce nutrient loads and protect water quality. The regulatory framework ensures compliance with stringent standards. The treated effluent likely discharges into Lake Como, which feeds the Adda River, a tributary of the Po River. The Po River flows into the Adriatic Sea, making this plant part of a large transboundary basin. Lake Como is a deep subalpine lake with significant ecological and touristic value, supporting diverse aquatic life and serving as a drinking water source for surrounding communities.

The plant discharges into Lake Como, a large subalpine lake in the Po River basin. The lake's outflow, the Adda River, flows through Lombardy before joining the Po River, which empties into the Adriatic Sea. The lake supports diverse aquatic ecosystems, including endemic fish species, and is a vital resource for tourism and drinking water. Nutrient loading from wastewater can contribute to eutrophication, making advanced treatment important for protecting this sensitive water body.
