Casal Brunori Wastewater Treatment Plant, Roma, Lazio, Italy

Casal Brunori is a wastewater treatment plant located in the Mercato di Mezzocammino area of Roma, in the Lazio region of Italy. It serves a population of approximately 3,600 people, classifying it as a small agglomeration under Italian and EU regulations. The plant operates with advanced treatment processes, ensuring high-quality effluent before discharge. As an advanced treatment facility, Casal Brunori goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The advanced level indicates the use of tertiary technologies such as nutrient removal or disinfection. The plant has a designed capacity of 3,600 cubic meters per day, matching the population served, and reports a discharge volume of 712.67 units, suggesting operational flexibility. The plant discharges treated wastewater into an inland water body within the Tiber River basin, which flows through Rome and into the Tyrrhenian Sea. This discharge supports the ecological health of local waterways and downstream environments. The plant's inland location reduces direct marine impact, but its proximity to the coast (within 50 km) means careful management is needed to protect coastal water quality.

Casal Brunori discharges into the Tiber River basin, which drains into the Tyrrhenian Sea near Rome. The Tiber River supports diverse aquatic life and is an important water resource for the region. The plant's advanced treatment helps minimize nutrient and pollutant loads, protecting downstream ecosystems including coastal zones that are ecologically sensitive and support tourism and fisheries.
