FOLLINA_VIA_GAVA Wastewater Treatment Plant, La Bella Ligonto, Veneto

FOLLINA_VIA_GAVA is a wastewater treatment plant located in La Bella Ligonto, a locality within the municipality of Follina in the Veneto region of Italy. The plant serves a small population of 871 people, reflecting its role in a rural or peri-urban setting. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment of urban wastewater. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 500 cubic meters per day and a current discharge volume of 172.43 cubic meters per day, the plant operates well below its capacity. This suggests it is sized to accommodate future growth or seasonal peaks. Secondary treatment typically involves activated sludge or similar biological systems. The treated effluent is discharged into local water bodies that ultimately drain into the Adriatic Sea via the Piave River basin. The Veneto region is known for its extensive river network and coastal lagoons, including the UNESCO World Heritage site of Venice Lagoon. The plant's location inland, more than 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the regional watershed.

The plant discharges into local streams that feed into the Piave River, which flows into the Adriatic Sea near Venice. The Piave River basin supports diverse aquatic life and is an important water resource for agriculture and tourism in the Veneto region. The downstream environment includes sensitive coastal ecosystems such as the Venice Lagoon, which is ecologically significant for migratory birds and marine biodiversity. Secondary treatment helps reduce organic pollution, but nutrient removal may be limited, potentially contributing to eutrophication in receiving waters.
