Overview
IDL_CELLANE is a secondary wastewater treatment plant serving Castel del Piano, Toscana, Italy. It treats wastewater from a small population of 267 with a designed capacity of 2000 m³/day.
IDL_CELLANE is a wastewater treatment plant located in Castel del Piano, within the Unione dei Comuni Montani Amiata Grossetana in the Toscana region of Italy. The plant serves a small population of 267 people, reflecting its role in a rural or small-town setting. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment of urban wastewater. The plant provides secondary treatment, a biological process that removes biodegradable organic matter and suspended solids. With a designed capacity of 2000 m³/day and a current discharge volume of 52.86 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The facility is inland, more than 50 km from the coast, reducing direct marine impact. The treated effluent is discharged into local watercourses that drain into the Tyrrhenian Sea via the Ombrone River basin. The region is characterized by hilly terrain and agricultural land, and the plant helps protect local streams and downstream ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into small streams that feed into the Ombrone River, which flows through southern Tuscany before entering the Tyrrhenian Sea near Grosseto. The Ombrone basin supports diverse aquatic life and is important for regional agriculture. The plant's secondary treatment reduces organic load and suspended solids, helping to maintain water quality in this ecologically sensitive area.
Frequently asked questions
IDL_CELLANE is located in Castel del Piano, in the Toscana region of Italy, within the Unione dei Comuni Montani Amiata Grossetana.
The plant serves a population of 267 people, typical of a small rural agglomeration.
The treated effluent is discharged into local streams that flow into the Ombrone River, which eventually reaches the Tyrrhenian Sea.
As a small agglomeration (under 2,000 population equivalent), IDL_CELLANE is subject to EU Directive 91/271/EEC, which requires appropriate treatment (secondary or equivalent) for discharges into freshwater and estuaries.
For small agglomerations in Italy, secondary treatment is standard, as provided by IDL_CELLANE. This biological process effectively reduces organic matter and suspended solids before discharge.
