Overview
San Pietro in Casale wastewater treatment plant serves the town of San Pietro in Casale in Emilia-Romagna, Italy. It treats wastewater for approximately 9,561 people.
The San Pietro in Casale wastewater treatment plant is located in the Emilia-Romagna region of northern Italy, serving the town of San Pietro in Casale and the surrounding Rubizzano area. The plant is part of the Unione Reno Galliera municipal consortium and handles wastewater from a population of about 9,561 residents. As a plant serving a medium agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), it is required to provide secondary treatment as a minimum. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, which is common in the Po River basin due to eutrophication concerns. The treated effluent is discharged into local waterways that ultimately flow into the Reno River, a major tributary of the Po River. The Po River delta and the Adriatic Sea are the final receptors. The plant plays a key role in protecting the Reno River and Po basin from nutrient pollution, supporting aquatic life and water quality in this agriculturally intensive region.
Environmental context
The plant discharges into the Reno River basin, which flows into the Po River and then the Adriatic Sea. The Po River delta is an ecologically sensitive area supporting diverse aquatic life and important migratory bird species. Nutrient loading from wastewater can contribute to eutrophication in the Adriatic, making effective treatment critical for downstream ecosystem health.
Frequently asked questions
The plant is located in San Pietro in Casale, in the Emilia-Romagna region of northern Italy, specifically in the Rubizzano area along Via Rubizzano.
The plant serves approximately 9,561 people, classifying it as a medium agglomeration under EU regulations.
Treated wastewater is discharged into local waterways that flow into the Reno River, a tributary of the Po River, which ultimately reaches the Adriatic Sea.
As an Italian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size and tertiary treatment if the receiving waters are sensitive.
Under the EU directive, plants serving between 2,000 and 10,000 people are required to provide secondary treatment. In sensitive areas like the Po basin, additional nutrient removal may be required.
