MARENE Wastewater Treatment Plant, Marene, Piemonte, Italy

MARENE is a wastewater treatment plant located in Marene, a town in the province of Cuneo, Piemonte, Italy. The plant serves a population of 2,820 and is designed to handle a capacity of 3,000 m³/day, with a current discharge volume of 632.23 m³/day. As a secondary treatment facility, MARENE provides biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size (2,000-10,000 population equivalent) are required to achieve secondary treatment standards, which this plant meets. The treated effluent is discharged into local watercourses that eventually drain into the Po River basin, which flows into the Adriatic Sea. The plant plays a key role in protecting the water quality of the Po River and its tributaries, supporting aquatic life and downstream ecosystems.

The plant discharges into the Po River basin, which is the largest river system in Italy, flowing eastward into the Adriatic Sea. The Po basin supports diverse aquatic habitats and is an important agricultural and industrial region. Effective wastewater treatment at MARENE helps reduce nutrient and pollutant loads, protecting downstream water quality and the ecological health of the Adriatic coastal zone.
