IDL_RIGNANO_VIA_DEL_MOLINO Wastewater Treatment Plant, Reggello, Tuscany

IDL_RIGNANO_VIA_DEL_MOLINO is a wastewater treatment plant located in Reggello, in the Tuscany region of Italy. It serves a population of approximately 3,958 people and has a designed capacity of 3,000 cubic meters per day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive for agglomerations of this size. As a secondary treatment facility, the plant uses biological processes to remove organic matter and suspended solids. The actual discharge volume is 783.54 m³/day, indicating the plant operates well below its design capacity. The plant is situated inland, more than 50 km from the coast, reducing direct marine impact. The treated effluent is discharged into the local watershed, which ultimately drains into the Arno River and then into the Tyrrhenian Sea. The Arno River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and urban use. The plant plays a key role in protecting this waterway from untreated sewage.

The plant discharges into the Arno River basin, which flows through Tuscany to the Tyrrhenian Sea. The Arno River supports a variety of fish species and is an important water source for the region. Downstream, the river passes through Florence and Pisa before reaching the sea, where it influences coastal water quality. The plant's secondary treatment helps reduce organic pollution and nutrient loading, protecting both freshwater and marine ecosystems.
