IDL_RIBUSSOLAIA is a wastewater treatment plant located in Chianciano Terme, a municipality in the province of Siena, Tuscany, Italy. The plant serves a population of about 22,271, placing it in the medium agglomeration category under EU regulations. It is situated in the Valdichiana Senese area, a region known for its thermal springs and agricultural landscape. As an Italian plant serving a population between 10,000 and 100,000, IDL_RIBUSSOLAIA is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum standard. The directive also mandates more advanced treatment if the plant discharges into sensitive areas, such as those prone to eutrophication. The regulatory framework ensures compliance with national and EU standards. The plant discharges treated wastewater into the local water system, which ultimately drains into the Tyrrhenian Sea via the Ombrone River basin. The area supports diverse aquatic life and is important for regional water quality management, particularly given the proximity to thermal springs and agricultural activities.

Environmental context

The plant's treated effluent enters the local drainage network within the Valdichiana Senese, a valley that feeds into the Ombrone River basin. The Ombrone flows southward through Tuscany and discharges into the Tyrrhenian Sea near Grosseto. This coastal zone supports important marine and coastal ecosystems, including seagrass meadows and fish nursery habitats. The region's thermal springs and agricultural runoff make nutrient management a key environmental consideration.
