ORISTANO_LOC_CIRRAS_Z_I_SANTA_GIUSTA Wastewater Treatment Plant, Santa Giusta, Sardinia

ORISTANO_LOC_CIRRAS_Z_I_SANTA_GIUSTA is a wastewater treatment plant located in Santa Giusta, in the province of Oristano, Sardinia, Italy. The plant serves a population of approximately 100,955, classifying it as a large agglomeration under EU regulations. Its location in the Sardinian coastal region places it within 50 kilometers of the Mediterranean Sea, making its discharge management critical for marine water quality. As a large agglomeration, the plant is expected to comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum, and tertiary treatment if discharging into sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure. The regulatory framework ensures that the plant meets stringent standards for pollutant removal. The treated effluent likely discharges into the Gulf of Oristano, part of the Mediterranean Sea, via local watercourses or directly. This coastal environment supports diverse marine life, including seagrass meadows and fish nurseries, making proper treatment essential to prevent eutrophication and protect biodiversity. The plant plays a key role in safeguarding the coastal waters of Sardinia.

The plant is situated near the Gulf of Oristano on the western coast of Sardinia, which drains into the Mediterranean Sea. This coastal area is ecologically sensitive, supporting seagrass meadows and important fish spawning grounds. Proper wastewater treatment is crucial to prevent nutrient pollution that could harm marine ecosystems and local fisheries.
