MURAVERA_LOC_COSTA_REY Wastewater Treatment Plant, Olia Speciosa, Sardinia

The MURAVERA_LOC_COSTA_REY wastewater treatment plant is located in Olia Speciosa, a locality in the municipality of Castiadas, in the province of Cagliari, Sardinia, Italy. It serves a population equivalent of 44,293, classifying it as a medium-sized agglomeration under Italian and EU regulations. The plant is situated along the Strada Statale 125 Orientale Sarda, a major road connecting the eastern coast of Sardinia. As an Italian wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into coastal or freshwater environments. The designed capacity is reported as 1.00, though the unit is unspecified. The regulatory framework mandates appropriate treatment to protect receiving waters. The plant is located within 50 km of the coast, indicating its discharge likely affects the Tyrrhenian Sea or nearby coastal lagoons. The surrounding area includes the Sarrabus-Gerrei region, characterized by Mediterranean scrubland and agricultural activities. Proper treatment is essential to safeguard the marine ecosystem, which supports tourism and fisheries along Sardinia's eastern coast.

The plant's treated effluent likely discharges into the Tyrrhenian Sea via local streams or directly, given its proximity to the coast. The receiving waters include the coastal zone near the Gulf of Cagliari, an area of ecological importance for seagrass meadows and marine biodiversity. Downstream, the waters flow into the broader Mediterranean Sea, which supports diverse aquatic life and is a key resource for local communities. The region's semi-arid climate means that water quality management is critical to prevent eutrophication and protect sensitive coastal habitats.
