The Saltpan of Margherita di Savoia, state-owned, is the biggest in Italy and the most advanced from the technological point of view in Europe. It extends over 4000hectares, got for the greatest part from the reclaimed land of Lake Salpi, made in the first years of 1900. The water of the sea is taken from a powerful water-scooping resort and put in the first evaporating zone of the tanks of "Alma Dannata", where it reaches a salinity of about 5°. From there it is carried in the second evaporating zone of the tanks of "Salpi Nuovo Alte", where it reaches, thanks to a difference in level, the low zone of "Salpi Nuovo".

The same water is later carried in the remaining third and fourth evaporating zones anf from these ones, it is disposed with an appropriate thickness in the "salting zone" where, between 25,7° and 29°, there is the evidence of sodium chloride. At the moment, the collection of salt lasts several years, the technique that permits many advantages both productive and economic with the utilisation of tracked machines. The collected salt is manufactured and wrapped up for different uses (alimentary, industrial, etc.)
