MONTERENZIO_PIZZANO Wastewater Treatment Plant, Cà di Bazzone, Italy

MONTERENZIO_PIZZANO is an advanced wastewater treatment plant located in Cà di Bazzone, a locality in the municipality of Monterenzio, within the Emilia-Romagna region of Italy. The plant serves a population of approximately 4,287 residents and is part of the municipal wastewater infrastructure managed by the Unione dei comuni Savena-Idice. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 5,000 m³/day and an actual discharge volume of 553.41 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. As an Italian facility, it operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on the sensitivity of receiving waters and population size. The treated effluent is discharged into local watercourses that drain into the Savena River, a tributary of the Idice River, which eventually flows into the Reno River and then into the Adriatic Sea. The plant plays a crucial role in protecting the water quality of these rivers and the downstream marine environment, supporting aquatic life and recreational uses.

The plant discharges into the Savena-Idice river system, which flows into the Reno River and ultimately reaches the Adriatic Sea. This watershed supports diverse aquatic ecosystems, including fish populations and riparian habitats. The advanced treatment helps minimize nutrient loading, reducing the risk of eutrophication in the Adriatic coastal zone, which is ecologically sensitive due to its shallow waters and high biodiversity.
