T_S_GIOVANNI_TERTENIA Wastewater Treatment Plant, Tertenia, Sardinia

T_S_GIOVANNI_TERTENIA is a wastewater treatment plant located in Tertenia, a town in the Ogliastra region of Sardinia, Italy. The plant serves a population of approximately 2,500 residents and is designed with a capacity of 2,500 cubic meters per day, indicating it is sized to match the local community's needs. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for plants discharging into sensitive environments, such as coastal areas. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are generally required to provide secondary treatment, but the advanced level here suggests additional safeguards for the receiving environment. The treated wastewater is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. The plant's proximity to the coast (within 10 km) means its effluent can influence coastal water quality. Advanced treatment helps protect marine ecosystems and supports recreational and economic uses of the coastal zone.

The plant discharges into the local drainage network that flows to the Tyrrhenian Sea, a basin of the Mediterranean Sea. The coastal waters near Tertenia support diverse marine life, including seagrass meadows and fish populations. Advanced treatment reduces nutrient loads, helping to prevent eutrophication and maintain water quality in this ecologically sensitive coastal environment.
