IDL Industriale Ex SMI Wastewater Treatment Plant - Campo Tizzoro, Toscana (Closed)

IDL Industriale Ex SMI is a former wastewater treatment plant located in Campo Tizzoro, a frazione of San Marcello Piteglio in the Pistoia province of Toscana, Italy. The plant was designed with a capacity of 500 cubic meters per day and provided secondary treatment for industrial wastewater. It is now closed and no longer operational. As a secondary treatment facility, IDL Industriale Ex SMI would have met the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for industrial discharges, which mandates secondary treatment for biodegradable industrial wastewater from certain sectors. The plant's closure suggests that industrial wastewater management in the area has been consolidated or redirected to other facilities. The plant is situated in the mountainous Appennino Pistoiese region, part of the Reno River basin. Treated effluent would have discharged into local streams that feed the Reno River, which flows northeast into the Adriatic Sea near Venice. The area is ecologically sensitive due to its Apennine location, supporting diverse aquatic life and serving as a corridor for migratory species.

The plant is located in the Apennine mountains of Toscana, within the Reno River basin. The Reno River flows through Emilia-Romagna and discharges into the Adriatic Sea. The local watershed includes small streams that support aquatic ecosystems in a mountainous terrain, with the downstream environment providing habitat for fish and other wildlife. The area's ecological sensitivity is tied to its role in maintaining water quality for both local biodiversity and the larger Po Valley drainage system.
