IDL_SAN_GIOVANNI_PIANETTO Wastewater Treatment Plant, Grosseto, Tuscany

IDL_SAN_GIOVANNI_PIANETTO is a wastewater treatment plant located in Grosseto, in the Tuscany region of Italy. The plant serves a population of approximately 93,646, classifying it as a large agglomeration under EU regulations. It is situated near the Tyrrhenian Sea coast, within 50 km of the shoreline. As a plant serving a population over 50,000, it falls under 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 thousands of cubic meters per day), indicating a substantial infrastructure to handle the region's wastewater. The treated effluent from the plant likely discharges into local watercourses that flow into the Tyrrhenian Sea. This coastal discharge requires careful management to protect marine ecosystems, including seagrass meadows and coastal biodiversity. The plant plays a key role in maintaining water quality in the Grosseto area and the broader Mediterranean coastal environment.

The plant is located in the Ombrone River basin, which drains into the Tyrrhenian Sea. The downstream environment includes coastal wetlands and marine habitats that support diverse aquatic life, including fish and migratory birds. The Tyrrhenian Sea is a semi-enclosed basin with limited water exchange, making it sensitive to nutrient pollution. Effective wastewater treatment is crucial to prevent eutrophication and protect the ecological balance of the coastal zone.
