Overview
Tombolo Via Campolongo Onara wastewater treatment plant serves Onara in Veneto, Italy. It treats wastewater for approximately 8,707 people under EU Urban Waste Water Treatment Directive standards.
The Tombolo Via Campolongo Onara wastewater treatment plant is located in Onara, a frazione of Tombolo in the Veneto region of northern Italy. The facility serves a population of approximately 8,707 people, placing it in the small-to-medium agglomeration category under EU classification. As a plant operating within the European Union, it is subject to the Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with EU standards. The treated effluent is discharged into local watercourses that ultimately drain into the Adriatic Sea via the Brenta River basin. The Veneto region features a network of rivers and canals that support agricultural irrigation and natural habitats. Proper wastewater treatment is essential to protect these water bodies from nutrient pollution and to maintain ecological balance in the downstream environment.
Environmental context
The plant discharges into the Brenta River basin, which flows through the Veneto plain and into the Adriatic Sea near Chioggia. The downstream environment includes agricultural areas and wetlands that support diverse aquatic life. Effective nutrient removal is critical to prevent eutrophication in the Adriatic, a semi-enclosed sea sensitive to nitrogen and phosphorus inputs.
