Soveria Simeri Gambarella Wastewater Treatment Plant, Calabria, Italy

The Soveria Simeri Gambarella wastewater treatment plant is located in Soveria Simeri, a municipality in the province of Catanzaro, Calabria, Italy. The plant serves a population of 1,138 and has a designed capacity of 2,000 m³/day, currently discharging 225.28 m³/day of treated wastewater. As a small agglomeration in a coastal area, the plant is subject to Italian regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge into sensitive coastal waters. The plant employs advanced treatment processes, ensuring a high level of pollutant removal beyond secondary standards. This is particularly important given its proximity to the coast, as advanced treatment reduces nutrient loads that could contribute to eutrophication in marine environments. The plant's discharge volume is well below its designed capacity, indicating operational headroom. The treated effluent from the plant flows into the Ionian Sea, a basin of the Mediterranean Sea. The coastal waters near Soveria Simeri support diverse marine life and are used for recreation and fishing. The advanced treatment helps protect these ecosystems from nutrient pollution and pathogens, maintaining water quality for both ecological and human uses.

The plant discharges into the Ionian Sea, part of the Mediterranean Sea, via local watercourses. The coastal zone near Soveria Simeri is ecologically sensitive, supporting seagrass meadows and marine biodiversity. Advanced treatment reduces nutrient loading, mitigating eutrophication risks in this oligotrophic marine environment.
