Santa Maria Nuova Dep Wastewater Treatment Plant, Santa Maria Nuova, Marche, Italy

Santa Maria Nuova Dep is an advanced wastewater treatment plant located in Santa Maria Nuova, a town in the Marche region of central Italy. The plant serves a population of approximately 3,261 residents and is designed to handle up to 2,500 cubic meters of wastewater per day, with an average discharge volume of 684.63 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. As a facility in Italy, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on the sensitivity of receiving waters and population served. For small agglomerations like this, advanced treatment is often implemented to protect local water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Adriatic Sea via rivers such as the Esino or Musone. The Marche region's rivers support diverse aquatic life and are important for agriculture and tourism. The plant's advanced treatment helps minimize nutrient loading and protects downstream ecosystems, including coastal areas within 50 km of the facility.
