Depuratore di Chizzola Wastewater Treatment Plant, Chizzola, Trentino-Alto Adige

Depuratore di Chizzola is a municipal wastewater treatment plant located in Chizzola, a frazione of Ala in the province of Trento, Trentino-Alto Adige/Südtirol, Italy. The plant serves a population of approximately 11,956 people, placing it in the medium agglomeration category under EU classification. It operates within the regulatory framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland discharges from agglomerations of this size. As a plant serving a medium-sized community in a mountainous region, the facility is expected to meet secondary treatment standards to protect the sensitive Alpine environment. The plant's design capacity and operational details are managed by local authorities under Italian national regulations implementing EU directives. The plant discharges treated wastewater into the Adige River basin, which flows through the Adige Valley southward to the Adriatic Sea. The Adige River is the second-longest river in Italy and supports diverse aquatic life, including fish species such as trout and grayling. The plant's operations are critical for maintaining water quality in this ecologically sensitive Alpine watershed, which also serves as a drinking water source for downstream communities.

The plant discharges into the Adige River basin, which flows through the Adige Valley in Trentino-Alto Adige and ultimately reaches the Adriatic Sea near Venice. The Adige River supports a diverse aquatic ecosystem, including native fish populations and migratory species. The surrounding Alpine environment is ecologically sensitive, with the river providing important habitat for wildlife and serving as a key water resource for agriculture and tourism in the region.
