FRAZ_COLLI_DI_PACE Wastewater Treatment Plant, Pescorocchiano, Lazio

FRAZ_COLLI_DI_PACE is an advanced wastewater treatment plant located in the hamlet of Colle di Pace, within the municipality of Pescorocchiano in the Lazio region of Italy. The plant serves a small population of 460 residents, reflecting its role in a rural or small community setting. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 600 m³/day and an actual discharge volume of 91.06 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. As an Italian facility, it operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for small agglomerations. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea via the Tiber River basin. The advanced treatment level helps protect the sensitive aquatic ecosystems of the region, including the Tiber River and its tributaries, which support diverse freshwater life and are important for regional water quality.

The plant discharges into the local water network that feeds into the Tiber River basin, which flows through central Italy before reaching the Tyrrhenian Sea. The Tiber River supports diverse aquatic habitats and is ecologically significant for migratory fish species. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in the river and coastal marine environment.
