Selvotta Wastewater Treatment Plant, Roma, Lazio, Italy

Selvotta is a wastewater treatment plant located in the Monte Migliore area of Roma, in the Lazio region of Italy. The plant serves a population of approximately 3,000 people, making it a small-scale facility within the broader municipal wastewater infrastructure of Rome. 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. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. With a designed capacity of 3,000 cubic meters per day and a reported discharge volume of 593.89 cubic meters per day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The advanced treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The treated wastewater from Selvotta ultimately drains into the Tiber River basin, which flows through Rome and into the Tyrrhenian Sea. The Tiber River is a major watercourse in central Italy, supporting diverse aquatic life and providing water for agriculture and industry. The plant's advanced treatment helps protect the river's ecological health and the downstream coastal environment.

Selvotta discharges into the Tiber River basin, which flows through Rome and empties into the Tyrrhenian Sea. The Tiber River supports a variety of fish species and is an important migratory corridor for birds. The advanced treatment at Selvotta helps reduce nutrient loads and pollutants, protecting the river's water quality and the downstream marine ecosystem from eutrophication and contamination.
