DP01203702_CASALZUIGNO is a municipal wastewater treatment plant located in Azzio, within the Comunità Montana Valli del Verbano in the province of Varese, Lombardia, Italy. The plant serves a population of approximately 10,320, classifying it as a medium agglomeration under EU regulations. As a plant operating under the EU Urban Waste Water Treatment Directive (91/271/EEC), it is required to provide secondary treatment as a minimum standard for agglomerations of this size. The directive also mandates appropriate treatment before discharge into sensitive areas, which may apply given the region's proximity to Lake Maggiore and the Po River basin. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Po River and then the Adriatic Sea. This water body supports diverse aquatic life and is an important ecological corridor in northern Italy. The plant's operation helps protect downstream water quality and the broader Po basin ecosystem.
Environmental context
The plant discharges into the local watershed that flows into the Po River, Italy's longest river, which empties into the Adriatic Sea. The Po basin supports extensive agriculture and diverse aquatic habitats, including fish species of conservation interest. The region is also near Lake Maggiore, a large subalpine lake that is ecologically sensitive and a key water resource.

Under the EU UWWTD, plants serving agglomerations of 10,000 to 150,000 population equivalent must provide secondary treatment. This plant meets that requirement as a medium-sized facility.
In Italy, plants of this scale typically employ secondary biological treatment, such as activated sludge or biofiltration, to meet EU standards for organic matter and suspended solids removal.
