CERIARA Wastewater Treatment Plant, Priverno, Lazio, Italy

CERIARA is an advanced wastewater treatment plant located in Ceriara di Priverno, in the Lazio region of Italy. The plant serves the local community of Priverno, a town in the province of Latina, and is designed to treat wastewater for a population equivalent of 1,000 people. Its advanced treatment level ensures high-quality effluent suitable for discharge into the local environment. The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. With a designed capacity of 1,000 m³/day and a current discharge volume of approximately 198 m³/day, the facility is operating well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea via the Amaseno River or nearby coastal streams. The plant plays a key role in protecting the water quality of the region's rivers and the downstream marine environment, supporting both ecological health and recreational uses.

The plant discharges into the local drainage basin that flows toward the Tyrrhenian Sea, likely via the Amaseno River or smaller coastal streams. The area supports diverse aquatic life and is part of a Mediterranean coastal ecosystem. The advanced treatment helps minimize nutrient loading and protects downstream habitats, including seagrass meadows and fish spawning grounds.
