PRATI_COMUNALE Wastewater Treatment Plant, Roccagorga, Lazio, Italy

PRATI_COMUNALE is an advanced wastewater treatment plant located in Roccagorga, a town in the Lazio region of central Italy. The facility serves a population of approximately 1,300 residents and is designed to handle up to 1,500 cubic meters of wastewater per day, with an average daily discharge of 257.35 cubic meters. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting the stringent requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations like Roccagorga (under 2,000 population equivalent), the directive mandates appropriate treatment, and the advanced level here ensures high-quality effluent. The treated effluent is discharged into local watercourses that eventually drain into the Tyrrhenian Sea via the Lazio coastal basin. The plant plays a crucial role in protecting the region's water resources, including the nearby Amaseno River and the Pontine Marshes, an ecologically sensitive area that supports diverse aquatic life and migratory birds.

The plant discharges into local streams that flow into the Amaseno River, which then reaches the Tyrrhenian Sea near Terracina. The Pontine Marshes, a coastal wetland of ecological importance, rely on clean water inflows from this basin. Advanced treatment helps minimize nutrient loading, protecting the marine environment and supporting biodiversity in the downstream coastal zone.
