DP01205301_COCQUIO_TREVISAGO Wastewater Treatment Plant, Cocquio Trevisago, Italy

DP01205301_COCQUIO_TREVISAGO is a municipal wastewater treatment plant located in Cocquio Trevisago, a town in the province of Varese, Lombardia, Italy. The plant serves a population of approximately 5,486 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). It is situated inland, more than 50 km from the coast, and discharges into the local hydrological network. As an Italian plant serving fewer than 10,000 population equivalents, it is subject to the EU UWWTD requirements, which mandate appropriate treatment based on the sensitivity of the receiving waters. For small agglomerations, secondary treatment or equivalent is typically required unless the discharge is into a less sensitive area. The plant's operational details, including treatment process and capacity, are managed by the local municipal authority. The treated effluent from the plant ultimately flows into the Bardello River, which drains into Lake Varese, a significant water body in the Lombardy region. Lake Varese is part of the Po River basin and supports diverse aquatic life. The plant plays a key role in protecting the lake's water quality and the downstream ecosystem.

The plant discharges into the Bardello River, which flows into Lake Varese, a shallow lake in the Po River basin. Lake Varese is ecologically sensitive, supporting diverse aquatic life and serving as a habitat for migratory birds. The lake ultimately drains via the Po River into the Adriatic Sea. The plant's treatment helps mitigate nutrient loading and protect the lake's ecological balance.
