VALLEFOGLIA Wastewater Treatment Plant, Monteleone di Spoleto, Umbria

VALLEFOGLIA is a wastewater treatment plant located in Ruscio, a frazione of Monteleone di Spoleto, in the Umbria region of central Italy. The plant serves a population of approximately 3,500 residents and is part of the municipal wastewater infrastructure for the area. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,000 m³/day and a current discharge volume of 692.88 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Tiber River basin. The Tiber flows through Umbria and Lazio before reaching the Tyrrhenian Sea near Rome. The advanced treatment helps protect the sensitive aquatic ecosystems of the Tiber River and its tributaries.

The plant discharges into the Tiber River basin, which flows through central Italy and empties into the Tyrrhenian Sea. The Tiber supports diverse aquatic life and is an important water resource for agriculture and drinking water downstream. The advanced treatment level helps minimize nutrient and pollutant loads, protecting the river's ecological health and the coastal waters of the Tyrrhenian Sea.
