San Giustino Selci Lama Wastewater Treatment Plant, Umbria, Italy

The San Giustino Selci Lama wastewater treatment plant is located in San Giustino, a town in the Umbria region of central Italy. The facility serves a population equivalent of 15,577, placing it in the medium agglomeration category under Italian and EU regulations. The plant is situated near the Tiber River, which flows through the region and ultimately reaches the Tyrrhenian Sea. As an Italian wastewater treatment plant, San Giustino Selci Lama operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving water body is designated as a sensitive area. The plant's treatment processes and capacity are managed to meet these regulatory standards, ensuring compliance with national and European water quality objectives. The plant's discharge contributes to the health of the Tiber River basin, a major watercourse in central Italy. The Tiber flows through Rome before emptying into the Tyrrhenian Sea, supporting diverse aquatic ecosystems and providing water for agriculture, industry, and recreation. Effective treatment at San Giustino Selci Lama helps protect downstream water quality and the ecological integrity of the Tiber watershed.

The plant discharges into the Tiber River basin, which drains through Umbria and Lazio into the Tyrrhenian Sea. The Tiber is a critical water resource for central Italy, supporting diverse aquatic life and providing water for human use. The downstream environment includes sensitive riverine habitats and coastal zones that benefit from reduced nutrient and pollutant loads from well-treated wastewater.
