CALUSO_MAZZE Wastewater Treatment Plant, Casale di Mazzè, Piemonte

CALUSO_MAZZE is a wastewater treatment plant located in Casale di Mazzè, a town in the Piemonte region of northwestern Italy. The plant serves a population equivalent of approximately 15,685, placing it in the medium-agglomeration category under EU classification. Its location in the Po River basin positions it within one of Italy's most agriculturally and industrially significant regions. As a plant serving a population between 10,000 and 150,000, it falls under the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment (biological treatment) as a minimum standard. The directive also requires more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant is expected to comply with these regulatory standards. The treated effluent from CALUSO_MAZZE likely discharges into a tributary of the Po River, which flows eastward across northern Italy into the Adriatic Sea. The Po basin supports diverse aquatic life and is a critical water resource for agriculture and industry. Proper treatment at this plant helps protect downstream water quality and the ecological health of the Po River and its delta.

The plant is situated in the Po River basin, Italy's largest and most economically important watershed. The Po River flows approximately 652 km eastward through the Po Valley, eventually discharging into the Adriatic Sea via a vast delta. This delta is an ecologically sensitive area that supports diverse aquatic and bird species, including migratory waterfowl. The plant's operations contribute to maintaining water quality in the basin, which is vital for irrigation, drinking water, and ecosystem health downstream.
