SANDRIGO_VIA_CHIESA Wastewater Treatment Plant, Ancignano, Veneto

SANDRIGO_VIA_CHIESA is an advanced wastewater treatment plant located in the hamlet of Ancignano, within the municipality of Sandrigo in the Veneto region of northern Italy. The plant serves a small population of 476 residents, reflecting its role in a rural or peri-urban setting. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 500 cubic meters per day and a discharge volume of 94.23 cubic meters per day, the facility operates well within its capacity. As an Italian plant, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels for agglomerations based on population size and receiving water sensitivity. The treated effluent is discharged into local watercourses that drain into the Bacchiglione River basin, eventually reaching the Adriatic Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Veneto plain and the Venice Lagoon system, supporting water quality and biodiversity in the region.

The plant discharges into the Bacchiglione River basin, which flows through the Veneto plain and into the Adriatic Sea near Chioggia. This region includes ecologically sensitive areas such as the Venice Lagoon, a unique coastal ecosystem that supports diverse aquatic life and migratory birds. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and preventing eutrophication in the lagoon.
