V_PAOLIERI Wastewater Treatment Plant, Impruneta, Tuscany

V_PAOLIERI is a wastewater treatment plant located in Impruneta, a town in the metropolitan city of Florence, Tuscany, Italy. The plant serves a small population of 62 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 treatment standards based on agglomeration size and receiving water sensitivity. As a primary treatment facility, V_PAOLIERI provides basic physical treatment to remove settleable solids. The plant has a designed capacity of 80 m³/day and currently discharges 12.27 m³/day of treated wastewater. For small agglomerations under 2,000 population equivalent, the EU directive allows primary treatment, provided the receiving waters are not designated as sensitive areas. The treated effluent from V_PAOLIERI flows into local streams that eventually drain into the Arno River basin. The Arno River passes through Florence and Pisa before reaching the Tyrrhenian Sea. This watershed supports diverse aquatic life and is ecologically important for the region. The plant's discharge contributes to the overall water quality management in the Arno catchment.

V_PAOLIERI discharges into local watercourses that are part of the Arno River basin. The Arno flows through Tuscany, passing Florence and Pisa, and empties into the Tyrrhenian Sea. This watershed supports diverse aquatic ecosystems and is used for irrigation and recreation. The plant's primary treatment reduces suspended solids but does not remove nutrients, so downstream water bodies may be affected by nutrient loading, particularly in sensitive areas.
