Nosedo Wastewater Treatment - History

Birth and Evolution of the Plant

The Nosedo wastewater treatment plant, the city’s oldest and largest sewage processing site, is situated in south-east Milan, in a location that lies between the built-up urban area and the vast irrigated meadowlands that stretch southwards, close to the Chiaravalle Abbey.

The area has a relevant natural and cultural value, with a complex hydrographical network of canals and springs whose lengthy history is connected to the territorial reclamation and re-organisation work performed by the Cistercian monks.

The first module was started in 2001 with a capacity of 300,000 population equivalents and reached full capacity on April 22, 2003 (official opening ceremony on May 13, 2003). The second module, which increased the plant’s processing capacity to 600-700,000 population equivalents, reached its full capacity on January 31, 2004. The plant as a whole reached its full capacity on October 30, 2004 (3 months ahead of agreed deadlines).

The plant is the end phase of a complex system that collects wastewater from the central and eastern part of Milan and has a processing capacity of 1,250,000 population equivalents.

The Nosedo plant was funded by a project financing scheme supported by two important banks: Banca Intesa and The Royal Bank of Scotland.

The concession consortium provided over 50% of the funds required for the project, in exchange for 16 years of plant management, before it was handed back over to the Municipal Authority in perfect working order, on November 9th, 2019.
