POSSAGNO_VIA_OLIVI Wastewater Treatment Plant, Possagno, Veneto, Italy

POSSAGNO_VIA_OLIVI is a municipal wastewater treatment plant located in Possagno, a town in the Veneto region of northern Italy. The plant serves a small population of 812 residents and is situated in the foothills of the Venetian Prealps, an area known for its scenic landscape and proximity to the Piave River basin. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. With a designed capacity of 750 m³/day, the facility is appropriately sized for the local community. The actual discharge volume is 160.75 m³/day, indicating a utilization rate well below capacity. The treated effluent is discharged into local watercourses that eventually drain into the Piave River, which flows into the Adriatic Sea near Venice. The Piave River is an important water body in the region, supporting diverse aquatic life and providing water for irrigation and recreation. The plant's secondary treatment helps protect the river's water quality and the downstream ecosystems of the Venice Lagoon.

The plant discharges into tributaries of the Piave River, which flows through the Veneto region into the Adriatic Sea. The Piave River basin supports a variety of aquatic species and is an important water resource for agriculture and tourism. The downstream environment includes the Venice Lagoon, a sensitive coastal ecosystem that benefits from reduced nutrient loads from upstream treatment plants. Secondary treatment at this facility helps minimize organic pollution and protect the ecological balance of the river and lagoon.
