The term "Conca" indicates a basin formed by an artificial canal whose main purpose is to raise the level of the water in a certain section so that more of it enters the side openings of the canal to allow the optimum irrigation of the fields. The basins were generally constructed to facilitate navigation and serve to eliminate differences in level of the waterway. The Conca Vinciana (based on drawings by Leonardo) of Inzago is located on Via Turati and has a cement footbridge with iron railing constructed over the locks. Peasants used it to cross the canal before Via Filippo Turati existed. Today, the footbridge is dangerous and is no longer used for pedestrian traffic.
