Wednesday the 17.02.2016 the Italian Minister of the Ambient stated: “In Genoa we are building one of the most important hydrogeological restructures ever done in Italy”. In this document the project related to the first allotment contract, called the Fereggiano River Diversion, is described: a 3.7 km long, 6 m wide tunnel that runs from the intake on the river, in the north of the city, to the east seaside, under some of the most densely populated neighborhood of the city. The excavation under the city with low overburden, the two principal construction sites on the richest seaside of the city and in the narrow riverbed of the Fereggiano, the secondary construction sites in the city tissue are the main issue of the contract.
