The Acquedotto Leopoldino (also known as the ""Acquedotto di Colognole"") and the neoclassical cisterns of Livorno were part of a sophisticated scheme to not only provide water to Livorno, but also clean it. The scheme was centred on the long aqueduct which runs south to north bringing water to the city from Colognole. This feat of engineering first carried water to the city in 1816, long before its completion. It was Livorno's sole water supply until 1912, still serving some areas of the city.
