IDL_STRADA_IN_CHIANTI Wastewater Treatment Plant, Strada in Chianti, Tuscany

IDL_STRADA_IN_CHIANTI is a municipal wastewater treatment plant located in Strada in Chianti, a frazione of Greve in Chianti in the Tuscany region of Italy. The plant serves a small population of 724 residents and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids before discharge. Its designed capacity is 500 cubic meters per day, with an average daily flow of approximately 143 cubic meters, indicating ample reserve capacity for future growth. The plant's treatment level meets the EU directive's requirements for agglomerations under 2,000 population equivalent in sensitive areas. The treated effluent is discharged into the local drainage network, which flows into the Arno River basin and eventually reaches the Tyrrhenian Sea. The plant plays a key role in protecting the region's water quality, supporting the ecological health of the Arno River and the coastal marine environment.

The plant discharges into the Arno River watershed, which drains through the Chianti hills and the city of Florence before reaching the Tyrrhenian Sea near Pisa. The Arno River supports diverse aquatic life and is an important migratory corridor for fish species. The downstream environment includes ecologically sensitive coastal areas and the Tyrrhenian Sea, which is a semi-enclosed basin with limited water exchange, making it vulnerable to nutrient enrichment from upstream sources.
