Overview
IDL_LA_CEPPA is an advanced wastewater treatment plant in Sinalunga, Tuscany, Italy, serving approximately 3,200 people with a designed capacity of 5,000 m³/day.
IDL_LA_CEPPA is an advanced wastewater treatment plant located in the municipality of Sinalunga, in the Valdichiana Senese area of Tuscany, Italy. The plant serves a population of about 3,200, with a designed capacity of 5,000 m³/day and a current discharge volume of 633.49 m³/day, indicating it operates well below its capacity. As an advanced treatment facility, IDL_LA_CEPPA goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (3,200 population equivalent), the directive requires secondary treatment, but the plant's advanced level provides additional environmental protection. The plant discharges treated wastewater into the local watershed, which drains into the Canale Maestro della Chiana and ultimately into the Arno River, flowing to the Tyrrhenian Sea. Its inland location and advanced treatment reduce risks to downstream ecosystems, supporting water quality in the Arno basin.
Environmental context
The plant is situated in the Valdichiana Senese, a valley in Tuscany, Italy. Treated effluent flows into the Canale Maestro della Chiana, a major drainage canal that connects to the Arno River. The Arno River is a significant watercourse in Tuscany, passing through Florence and Pisa before reaching the Tyrrhenian Sea. The watershed supports diverse aquatic life and is used for irrigation and recreation. The advanced treatment at IDL_LA_CEPPA helps protect the Arno basin from nutrient pollution, which can cause eutrophication in coastal areas.
