FONTE VIA CASTELLANA Wastewater Treatment Plant, Onè di Fonte, Veneto

FONTE VIA CASTELLANA is an advanced wastewater treatment plant located in Onè di Fonte, a frazione of Fonte in the Veneto region of northern Italy. The plant serves a population of 1,551 and has a design capacity of 2,000 cubic meters per day, with an average discharge volume of 307.04 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive areas. For a plant of this scale (serving fewer than 2,000 people), the directive mandates appropriate treatment to protect local water quality. The treated effluent is discharged into local watercourses that drain into the Piave River basin, eventually reaching the Adriatic Sea. The plant plays a key role in protecting the region's water resources, supporting both ecological health and downstream uses such as agriculture and recreation.

The plant discharges into local streams that feed into the Piave River, a major watercourse in the Veneto region that flows into the Adriatic Sea near Jesolo. The Piave basin supports diverse aquatic life and is an important ecological corridor. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and the sensitive coastal environment of the northern Adriatic.
