Limana Cesa Wastewater Treatment Plant, Limana, Veneto, Italy

Limana Cesa is a wastewater treatment plant located in the town of Cesa, within the municipality of Limana, in the Veneto region of northern Italy. The plant serves a small population of 805 residents, 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 wastewater. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU directive for smaller agglomerations. It has a designed capacity of 1000 m³/day and currently discharges 159.36 m³/day, indicating significant spare capacity. Advanced treatment typically includes nutrient removal or other tertiary processes to protect sensitive receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Piave River, a major river in the Veneto region that flows into the Adriatic Sea. The Piave River supports diverse aquatic life and is an important ecological corridor. The plant's advanced treatment helps protect this downstream environment from nutrient pollution and other contaminants.

The plant discharges into the local drainage network that feeds the Piave River, which flows southeast through the Veneto region and empties into the Adriatic Sea near Jesolo. The Piave River basin supports a variety of fish species and is used for irrigation and recreation. The advanced treatment at Limana Cesa helps reduce nutrient loads, protecting the river's ecological health and the coastal waters of the northern Adriatic, which are sensitive to eutrophication.
