TODI_PIAN_DEI_MORI Wastewater Treatment Plant, Todi, Umbria

TODI_PIAN_DEI_MORI is a wastewater treatment plant located in Todi, a town in the Umbria region of central Italy. The plant serves a small population of 252 residents and is situated along the Strada Statale 3 bis Tiberina, near the Tiber River. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for treatment based on agglomeration size and receiving water sensitivity. The plant provides advanced (tertiary) treatment, which includes nutrient removal to protect sensitive water bodies. Its designed capacity is 800 cubic meters per day, and it currently treats an average daily volume of approximately 50 cubic meters, indicating significant spare capacity. The advanced treatment level exceeds the EU requirement for small agglomerations, which typically mandates secondary treatment for populations under 2,000. The treated effluent is discharged into the Tiber River basin, which flows through Umbria and Lazio before reaching the Tyrrhenian Sea near Rome. The Tiber is a major Italian river supporting diverse aquatic life and providing water for agriculture and drinking. The plant's advanced treatment helps reduce nutrient loading, protecting downstream ecosystems and the coastal marine environment.

The plant discharges into the Tiber River basin, which flows through central Italy to the Tyrrhenian Sea. The Tiber supports a variety of fish species and is an important migratory corridor for birds. Advanced treatment at this plant reduces nitrogen and phosphorus loads, helping to prevent eutrophication in the river and its coastal receiving waters.
