CASTELVECCHIO_MPR_DEP - Advanced Wastewater Treatment Plant in Monte Porzio, Italy

CASTELVECCHIO_MPR_DEP is an advanced wastewater treatment plant located in Monte Porzio, in the province of Pesaro e Urbino, Marche region, Italy. The plant serves a population of 2,756 people, reflecting a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). Its designed capacity is 3,150 m³/day, with a current discharge volume of 545.59 m³/day, indicating operational headroom. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As an Italian facility, it operates under national regulations transposing the EU directive, with oversight from regional environmental authorities. The plant is located within 10 km of the Adriatic Sea coast, making its discharge environmentally significant. Treated effluent likely flows into local watercourses that drain into the Adriatic, a semi-enclosed sea with sensitive marine ecosystems. The advanced treatment level helps mitigate nutrient loading and protects coastal water quality, supporting biodiversity and tourism in the region.

The plant discharges into local watercourses that ultimately drain into the Adriatic Sea, a semi-enclosed basin with limited water exchange. The Adriatic supports diverse marine life, including seagrass meadows and fish nurseries, and is vulnerable to eutrophication from nutrient inputs. The advanced treatment level reduces nitrogen and phosphorus loads, helping to protect coastal water quality and the ecological health of the Adriatic ecosystem.
