Santhià Wastewater Treatment Plant, Santhià, Piemonte, Italy

The Santhià wastewater treatment plant is located in the town of Santhià, in the Piemonte region of northern Italy. It serves a population of approximately 9,216 people, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its treated effluent is discharged into the local water network. As a plant serving fewer than 10,000 people, it falls under the EU UWWTD requirements for appropriate treatment based on the sensitivity of the receiving waters. In Italy, such plants are typically subject to national regulations that implement the directive, often requiring secondary treatment or equivalent. The plant's operational details, including specific treatment processes and capacity, are managed by the local municipal authority. The treated wastewater from Santhià ultimately drains into the Po River basin, which is the largest river system in Italy. The Po River flows eastward into the Adriatic Sea, supporting diverse aquatic life and agricultural activities along its course. The plant's operations contribute to protecting the water quality of this important regional watershed.

The Santhià plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River is a vital water resource for northern Italy, supporting agriculture, industry, and ecosystems. The plant's effluent must meet quality standards to protect the river's ecological health, including fish populations and migratory species. The region's climate is temperate, with seasonal variations affecting river flow and dilution capacity.
