RODI Wastewater Treatment Plant, Cervaro, Lazio, Italy

RODI is a wastewater treatment plant located in Cervaro, a town in the province of Frosinone, Lazio, Italy. The plant serves a population of 2,910 and operates with advanced treatment processes, ensuring high-quality effluent before discharge. It has a designed capacity of 3,000 cubic meters per day and currently treats an average daily volume of 576.08 cubic meters. As an advanced treatment facility, RODI goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, and Italy's implementation often mandates advanced treatment in sensitive areas. The plant's capacity utilization is low, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local water system, which ultimately drains into the Tyrrhenian Sea via the Liri-Garigliano river basin. This region is ecologically sensitive, supporting diverse aquatic life and agricultural activities downstream. The advanced treatment helps protect water quality in the receiving water bodies and the coastal marine environment.

The plant discharges into the Liri-Garigliano river basin, which flows through Lazio and Campania before reaching the Tyrrhenian Sea. This watershed supports irrigated agriculture and freshwater ecosystems, including habitats for fish and migratory birds. The advanced treatment reduces nutrient loading, helping to prevent eutrophication in the coastal zone, which is important for tourism and fisheries.
