Borgo Piave Wastewater Treatment Plant, Latina, Lazio, Italy

Borgo Piave is a wastewater treatment plant located in the hamlet of Borgo Piave, part of the municipality of Latina in the Lazio region of Italy. The plant serves a population of approximately 2,800 residents, reflecting its role in managing domestic wastewater for a small community within the Pontine Plain area. The plant provides advanced treatment, which goes 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 3,000 cubic meters per day and an average daily discharge of 554.30 cubic meters, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Tyrrhenian Sea via the Pontine coastal basin. The region's flat terrain and agricultural land use make proper wastewater treatment essential to prevent nutrient enrichment in downstream coastal waters and protect the sensitive marine ecosystem of the central Tyrrhenian coast.

The plant discharges into the Pontine coastal basin, a network of canals and natural waterways that flow into the Tyrrhenian Sea near Latina. This coastal area supports diverse marine life and is an important zone for fisheries and tourism. Advanced treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the shallow coastal waters, which are ecologically sensitive due to their role as nursery habitats for fish and mollusks.
