CONTRADA S. QUIRICO Wastewater Treatment Plant, San Quirico, Lazio

CONTRADA S. QUIRICO is a wastewater treatment plant located in San Quirico, a locality in the municipality of Serrone, in the province of Frosinone, Lazio, Italy. The plant serves a small population of 200 residents, reflecting its role in a rural or small community setting. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 200 cubic meters per day and a current discharge volume of 39.59 cubic meters per day, the plant operates well within its capacity. The treated effluent is discharged into local water bodies that ultimately drain into the Tyrrhenian Sea via the Sacco River basin. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Lazio region, supporting water quality and biodiversity in the downstream environment.

The plant discharges into the Sacco River basin, which flows through the Lazio region and eventually reaches the Tyrrhenian Sea. This coastal sea is ecologically sensitive, supporting diverse marine life and important fisheries. Advanced treatment at the plant helps reduce nutrient loads and pollutants, safeguarding the riverine and marine ecosystems from eutrophication and contamination.
