Overview
Casale Monferrato wastewater treatment plant serves about 44,000 people in Piemonte, Italy. It operates under the EU Urban Waste Water Treatment Directive, which requires secondary treatment for agglomerations of this size.
The Casale Monferrato wastewater treatment plant is located in the town of Casale Monferrato, in the Piemonte region of northwestern Italy. It serves a population of approximately 44,130, classifying it as a medium-sized agglomeration under EU regulations. As a plant in Italy, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The directive also requires more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into local watercourses that eventually drain into the Po River, Italy's longest river, which flows eastward into the Adriatic Sea. The Po basin supports extensive agriculture and diverse aquatic ecosystems, making proper wastewater treatment critical for water quality and ecological health.
Environmental context
The plant discharges into the Po River basin, which drains into the Adriatic Sea. The Po River is a major waterway in northern Italy, supporting irrigation, industry, and biodiversity. Downstream ecosystems include wetlands and delta habitats that are important for migratory birds and fish species. Effective treatment helps reduce nutrient loading and protects these sensitive environments.
