PIUMAROLA Wastewater Treatment Plant, Villa Santa Lucia, Lazio, Italy

PIUMAROLA is an advanced wastewater treatment plant located in the Piumarola area of Villa Santa Lucia, in the province of Frosinone, Lazio, Italy. The plant serves a population of approximately 2,200 residents and has a designed capacity of 2,200 cubic meters per day, with a current discharge volume of 435.52 cubic meters per day. As an advanced treatment facility, PIUMAROLA goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas and agglomerations of this scale. The treated effluent from PIUMAROLA is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea via the Liri-Garigliano river system. This region supports diverse aquatic life and is important for maintaining water quality in the downstream coastal environment.

PIUMAROLA discharges into the Liri-Garigliano river basin, which flows through central Italy and empties into the Tyrrhenian Sea near the Gulf of Gaeta. The downstream environment includes ecologically sensitive coastal zones that support marine biodiversity and are important for local fisheries. Advanced treatment at this plant helps reduce nutrient loading and protects the receiving waters from eutrophication.
