DEP_COM_ROSETO Wastewater Treatment Plant, Gallicano nel Lazio, Lazio, Italy

DEP_COM_ROSETO is an advanced wastewater treatment plant located in Gallicano nel Lazio, within the Lazio region of Italy. The plant serves a population of approximately 4,700 residents and has a designed capacity of 6,400 cubic meters per day, with an average discharge volume of 930.43 cubic meters per day. As an advanced treatment facility, it 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 ensures compliance with national water quality goals. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. The Lazio region features a Mediterranean climate with seasonal rainfall, and the receiving water bodies support diverse aquatic ecosystems. The plant plays a key role in protecting downstream water quality and public health.

The plant discharges into the local water system that flows toward the Tyrrhenian Sea, a key basin of the Mediterranean Sea. The watershed supports diverse aquatic life and is an important ecological corridor. The advanced treatment helps minimize nutrient loading and protects downstream habitats from eutrophication.
