DOMEGGE_DI_CADORE_PIANI_DI_VALLESELLA Wastewater Treatment Plant, Grea, Italy

DOMEGGE_DI_CADORE_PIANI_DI_VALLESELLA is an advanced wastewater treatment plant located in Grea, a locality within the municipality of Domegge di Cadore in the Veneto region of northeastern Italy. The plant serves a population of approximately 3,064 people and has a designed capacity of 6,000 cubic meters per day, with an average discharge volume of 606.56 cubic meters per day. It operates in the alpine setting of the Cadore area, near the Piave River basin. 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 serving around 3,000 people, the directive mandates at least secondary treatment, and the advanced level indicates compliance with stricter standards for sensitive water bodies. The treated effluent likely discharges into a local watercourse that feeds into the Piave River, which flows southward to the Adriatic Sea near Venice. The plant plays a key role in protecting the Piave River ecosystem and the downstream Venetian Lagoon, supporting water quality for aquatic life and recreational uses in the Dolomites region.

The plant is situated in the alpine Cadore region, within the Piave River watershed. The Piave River flows from the Alps to the Adriatic Sea, passing through areas of ecological importance. The advanced treatment helps protect the river's water quality, which supports diverse aquatic life and is used for irrigation and recreation. Downstream, the Piave contributes to the Venetian Lagoon, a sensitive coastal ecosystem that benefits from reduced nutrient loads.
