FRAZIONE_COLLE_IATELLA Wastewater Treatment Plant, San Donato Val di Comino, Lazio

FRAZIONE_COLLE_IATELLA is an advanced wastewater treatment plant located in San Donato Val di Comino, a town in the province of Frosinone, Lazio, Italy. The plant serves a population of 700 and has a designed capacity of 1000 cubic meters per day, with an annual discharge volume of 138.58 megaliters. 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 small agglomerations like this, the directive requires appropriate treatment before discharge into sensitive areas. The plant discharges into the local watershed, which ultimately drains into the Liri River and then the Garigliano River, flowing into the Tyrrhenian Sea. This region supports diverse aquatic life and is part of a broader ecological network in central Italy.

The plant discharges into the local watershed that feeds the Liri River, a major watercourse in Lazio. The Liri joins the Garigliano River, which flows into the Tyrrhenian Sea near the Gulf of Gaeta. This coastal area supports diverse marine and estuarine habitats, including important nursery grounds for fish. The advanced treatment helps protect downstream water quality and ecological health.
