IDL_BARDALONE Wastewater Treatment Plant, Campo Tizzoro, Toscana

IDL_BARDALONE is a former wastewater treatment plant located in Campo Tizzoro, a frazione of San Marcello Piteglio in the Pistoia province of Tuscany, Italy. The plant served the local community in the Apennine mountains and is now closed. As a secondary treatment facility, IDL_BARDALONE would have provided biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), secondary treatment is the standard requirement for inland freshwater discharges. The plant's designed capacity of 800 m³/day suggests it served a small agglomeration, likely fewer than 10,000 population equivalents. The plant's discharge would have entered a local watercourse in the Reno River basin, which flows northward to the Adriatic Sea near Venice. The mountainous terrain of the Apennines means the receiving waters are likely sensitive to nutrient pollution, supporting diverse aquatic life in a region known for its natural springs and biodiversity.

The plant is located in the Tuscan Apennines, within the Reno River basin. Treated effluent would have flowed into a tributary of the Reno River, which eventually reaches the Adriatic Sea. The surrounding watershed is ecologically sensitive, supporting diverse aquatic species and serving as an important corridor for migratory fish. The mountainous terrain and proximity to natural springs make the area particularly vulnerable to nutrient enrichment from wastewater discharges.
