CODIGORO Wastewater Treatment Plant, Pontemaodino, Codigoro, Italy

The CODIGORO wastewater treatment plant is located in Pontemaodino, a locality within the municipality of Codigoro in the province of Ferrara, Emilia-Romagna, Italy. The plant serves a population of about 10,082 people and is situated in the Po Delta area, a region known for its extensive river network and agricultural activity. As a plant serving a medium-sized agglomeration in Italy, CODIGORO operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for inland plants serving between 2,000 and 10,000 population equivalent (PE) and more stringent treatment for discharges into sensitive areas. The Po Delta is designated as a sensitive area under the directive, necessitating advanced treatment to reduce nutrient loads. The plant discharges into the Po River delta, which flows into the Adriatic Sea. The Po Delta is a crucial ecological zone, supporting diverse aquatic life and serving as a migratory corridor for birds. The treatment plant plays a key role in protecting the delta's water quality and the downstream marine environment from nutrient pollution.

The CODIGORO plant discharges into the Po River delta, which empties into the northern Adriatic Sea. The Po Delta is a vast wetland ecosystem that supports diverse aquatic flora and fauna, including fish species and migratory birds. Nutrient loading from wastewater can contribute to eutrophication in the Adriatic, making effective treatment essential for preserving water quality and ecological balance in this sensitive coastal region.
