IDL_SAN_GIOVANNI PITIGLIANO Wastewater Treatment Plant, Pitigliano, Tuscany

IDL_SAN_GIOVANNI_PITIGLIANO is a municipal wastewater treatment plant located in Pitigliano, a town in the province of Grosseto, Tuscany, Italy. The plant serves a population of approximately 2,600 residents and is part of the regional wastewater infrastructure managed by the Unione di Comuni Montani Colline del Fiora. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,000 m³/day and a current discharge volume of 515.30 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea. The plant plays a key role in protecting the region's water quality, particularly the Fiora River basin, which supports diverse aquatic life and is important for local agriculture and tourism.

The plant discharges into the Fiora River basin, which flows through southern Tuscany and into the Tyrrhenian Sea near the Maremma coast. This watershed supports a mix of agricultural, natural, and recreational uses. The downstream environment includes ecologically sensitive coastal areas that benefit from the plant's secondary treatment, which reduces organic load and protects marine habitats.
