SS_CROCIFISSO_TRE_DEP Wastewater Treatment Plant, Chiesanuova, Treia, Italy

SS_CROCIFISSO_TRE_DEP is an advanced wastewater treatment plant located in Chiesanuova, a frazione of Treia in the province of Macerata, Marche, Italy. The plant serves a small population of approximately 1,093 people, reflecting its role in a rural or peri-urban setting. Its full address is Strada Provinciale 128 Treiese, Chiesanuova, Treia, Macerata, Italia. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 980 m³/day and a current discharge volume of 216.38 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations based on population equivalent and receiving water sensitivity. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Adriatic Sea via the Potenza River basin. The Marche region features a hilly terrain with rivers flowing eastward to the Adriatic. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the Adriatic coastal zone, which is important for tourism and fisheries.

The plant discharges into the Potenza River basin, which flows eastward through the Marche region into the Adriatic Sea. The Adriatic Sea is a semi-enclosed basin with sensitive coastal ecosystems, including seagrass meadows and nursery areas for fish. Advanced treatment at this plant reduces nutrient loads, helping to mitigate eutrophication risks in the coastal zone. The surrounding watershed supports agricultural activities and small urban centers, making pollution control critical for maintaining water quality.
