Depuratore Pescia Romana - Advanced Wastewater Treatment Plant in Lazio, Italy

Depuratore Pescia Romana is a wastewater treatment facility located in the town of Pescia Romana, part of the municipality of Montalto di Castro in the Viterbo province of Lazio, Italy. The plant serves a population of approximately 2,700 residents and has a designed capacity of 3,200 cubic meters per day, with an average daily discharge volume of 534.50 cubic meters. The plant employs advanced treatment processes, going beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is particularly important given the plant's coastal location, as it helps minimize nutrient and pollutant loads entering sensitive marine environments. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Tyrrhenian Sea. The coastal waters in this area support diverse marine life and are part of a broader Mediterranean ecosystem that includes seagrass meadows and important fish nursery habitats. The plant's advanced treatment helps protect these downstream ecological resources from eutrophication and other pollution impacts.

The plant discharges into the coastal zone of the Tyrrhenian Sea near Pescia Romana, a stretch of the Italian coast known for its sandy beaches and marine biodiversity. The receiving waters are part of the Mediterranean Sea, which supports seagrass meadows (Posidonia oceanica) and serves as a migratory corridor for marine species. The advanced treatment level reduces nutrient loading, helping to prevent algal blooms and preserve water quality in this ecologically sensitive coastal area.
