DEPURATORE LOCALITA SAN GIORGIO - Advanced Wastewater Treatment Plant in Nepi, Lazio, Italy

DEPURATORE LOCALITA SAN GIORGIO is an advanced wastewater treatment plant located in Nepi, a town in the province of Viterbo, Lazio, Italy. The plant serves a population of approximately 5,000 people, providing advanced treatment to protect local water quality. It is situated inland, more than 10 km from the coast, and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 5,000 cubic meters per day and a current discharge volume of 989.82 cubic meters per day, the plant operates well within its capacity. As an advanced treatment facility serving a small agglomeration, it meets the stringent requirements for sensitive areas under the EU directive. The treated effluent is discharged into local watercourses that eventually drain into the Tyrrhenian Sea via the Tiber River basin. The plant plays a key role in protecting the region's water resources, supporting both ecological health and downstream uses such as agriculture and recreation.

The plant discharges into local streams that flow into the Tiber River, which ultimately reaches the Tyrrhenian Sea. The Tiber basin supports diverse aquatic life and is an important migratory corridor for fish. Advanced treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality for human and ecological use.
