LOC_COLLE_S_GIUSTO Wastewater Treatment Plant, Sgurgola, Lazio, Italy

LOC_COLLE_S_GIUSTO is an advanced wastewater treatment plant located in Sgurgola, a municipality in the province of Frosinone, Lazio, Italy. The plant serves a population of 2,050 and has a designed capacity of 2,500 cubic meters per day, with a current discharge volume of 405.83 cubic meters per day. It 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. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus. This level of treatment is typical for plants discharging into sensitive areas or water bodies prone to eutrophication. The plant's capacity utilization is low relative to its design, indicating potential for future growth or seasonal variability in flow. The treated effluent is discharged into a local watercourse that eventually drains into the Tyrrhenian Sea via the Sacco River and the Liri-Garigliano river system. The region's water bodies support diverse aquatic life and are important for agriculture and tourism. Advanced treatment helps protect downstream ecosystems from nutrient pollution.

The plant discharges into a tributary of the Sacco River, which flows into the Liri River and then the Garigliano River before reaching the Tyrrhenian Sea. The downstream watershed includes agricultural areas and natural habitats that support fish and bird species. Advanced treatment reduces nutrient loads, helping to prevent eutrophication in the coastal marine environment.
