IDL_PONTE_A_CHIANI is a wastewater treatment plant located in Chiani, a locality within the municipality of Arezzo in the Tuscany region of Italy. The plant serves a population of approximately 9,400 people, classifying it as a small to medium agglomeration under European Union regulations. As an Italian plant, IDL_PONTE_A_CHIANI operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000 discharging into freshwater or estuaries. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Arno River basin. The Arno flows through Florence and Pisa before reaching the Tyrrhenian Sea. This water body supports diverse aquatic life and is an important resource for agriculture and tourism in the region.
Environmental context
The plant discharges into the Arno River basin, which flows through central Tuscany and empties into the Tyrrhenian Sea near Pisa. The Arno River supports a variety of fish species and is a key water source for irrigation and recreation. Downstream ecosystems include coastal wetlands and marine habitats that depend on good water quality from upstream treatment plants.
