SUD_OVEST_DUOMO_RCN_DEP Wastewater Treatment Plant, Recanati, Italy

SUD_OVEST_DUOMO_RCN_DEP is an advanced wastewater treatment facility located in Contrada San Pietro, Recanati, in the Macerata province of Italy. The plant serves a population of approximately 2,305 people and has a design capacity of 7,000 m³/day, with a reported discharge volume of 456.31 m³/day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment, but Italy often mandates advanced treatment in sensitive areas to protect water quality. The plant is located within 10 km of the Adriatic coast, and its treated effluent likely discharges into a local watercourse that flows into the Adriatic Sea. This coastal proximity underscores the importance of advanced treatment to minimize nutrient loading and protect marine ecosystems in the Adriatic basin.

The plant's discharge enters a local stream that flows into the Adriatic Sea, a semi-enclosed basin with limited water exchange. The Adriatic Sea supports diverse marine life, including seagrass meadows and fish nurseries, and is sensitive to nutrient pollution. Advanced treatment helps reduce eutrophication risks in this coastal environment.
