IDL_PECCIOLI Wastewater Treatment Plant, Peccioli, Tuscany

IDL_PECCIOLI is an advanced wastewater treatment plant located in Peccioli, a municipality in the province of Pisa, Tuscany, Italy. The plant serves a population of approximately 3,193 residents, making it a small-scale facility within the region's wastewater infrastructure. It is situated inland, more than 10 km from the coast, and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. Its designed capacity is 3,100 cubic meters per day, and it handles a discharge volume of 632.10 cubic meters per day, indicating a utilization rate well below capacity. The facility is part of the municipal wastewater system managed by local authorities. The treated effluent is discharged into the local water network, which ultimately drains into the Arno River basin and then into the Tyrrhenian Sea. The plant plays a key role in protecting the water quality of the surrounding environment, including the nearby Era River and the downstream coastal ecosystems. Its advanced treatment ensures high removal of nutrients and pollutants, supporting the ecological health of the region.

The plant discharges into the local watershed, which is part of the Arno River basin. The Arno flows through Tuscany and empties into the Tyrrhenian Sea near Pisa. The downstream environment includes sensitive coastal habitats and marine ecosystems that benefit from the plant's advanced treatment, which reduces nutrient loading and protects water quality in the region.
