Overview
Montalto Dora wastewater treatment plant serves Ivrea, Piemonte, Italy, treating wastewater for approximately 6,250 people. The plant discharges into the Dora Baltea river, part of the Po River basin.
The Montalto Dora wastewater treatment plant is located near Ivrea in the Piemonte region of Italy, serving a population of about 6,250. It is situated along the Dora Baltea river, which flows through the Alpine foothills. As a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is expected to provide at least secondary treatment to protect the receiving water body. Under the EU UWWTD, agglomerations between 2,000 and 10,000 population equivalent require secondary treatment unless the receiving waters are designated as sensitive areas, which would mandate more advanced treatment. The plant's location in the Po River basin, which drains into the Adriatic Sea, means it contributes to the overall nutrient load management in the region. Italian regulations implement the directive through national decrees, with oversight by regional environmental agencies. The treated effluent from Montalto Dora flows into the Dora Baltea, a tributary of the Po River. The Po River is Italy's longest river and supports extensive agriculture, industry, and biodiversity. Downstream, the Po Delta is an ecologically important area with wetlands and lagoons that provide habitat for migratory birds and aquatic species. Effective wastewater treatment at plants like Montalto Dora helps reduce nutrient pollution and protect these downstream ecosystems.
Environmental context
The plant discharges into the Dora Baltea river, which flows into the Po River, eventually reaching the Adriatic Sea. The Po River basin is a densely populated and agriculturally intensive region, making nutrient management critical. Downstream, the Po Delta features extensive wetlands and lagoons that support diverse aquatic life and migratory birds. The plant's treatment performance directly influences water quality in this ecologically sensitive area.
Frequently asked questions
The Montalto Dora wastewater treatment plant is located near Ivrea in the Piemonte region of Italy, along the Dora Baltea river.
The plant serves approximately 6,250 people, classifying it as a small agglomeration under EU regulations.
Treated effluent from the plant is discharged into the Dora Baltea river, which flows into the Po River and eventually reaches the Adriatic Sea.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size, unless the receiving waters are designated as sensitive.
For small agglomerations in Italy, secondary treatment is standard under the EU UWWTD. In sensitive areas, tertiary treatment may be required to reduce nutrients.
