The saltpan stretches on a strip of land approximately 20 km long, and goes deep inland for nearly 5 km. The total surface is about 45.000 hectares (one hectare = 2.471 acres). The available surface covered by water is about 4.000 hectares. This surface is divided in an evaporation section(3.500 hectares) and a salt one (500 hectares).

The remaining 500 hectares are occupied by roads, embankments, stockpiling areas, workshops, offices, lodgings, etc. The evaporation surface is needed to bring sea water to a saturation point as regards sodium chloride (sea water has a density of 3.5 Baumè (Bè) and saturation is reached at a density of 25.7 Bè and at a temperature of about 15° C); the remaining surface covered by water makes up the salt section in which salt is available.

This area is constantly nourished by saturated water prepared in the evaporation area and reaches, at the end of the salification process, 30 degrees Bè.

The evaporation pools of the saltpan have variable forms and surfaces depending on the altimetrical trend of the terrain. The salt pools, even though they preserve the variability in surface, have, on the contrary, perfectly regular forms to make "harvest" easier. The terrain is mainly clay and is highly permeable.

The water movement in a continuous cycle is obtained by exploiting, for most part of the surface, the natural difference in level of the terrain; when this is not possible, it is obtained by six water-scooping stations located in various areas of the saltpan. The first of the six stations, and the largest, is the one which scoops up sea water.

The quantity of sea water used for the production of salt depends on the seasonal trend; it is in the average of 30.000.000 cubic meters per year. When sea water reaches the point of saturation (25.7 Bè) its volume is reduced by one tenth; when it reaches its final saturation of 30 Bè, its initial volume is reduced by one fortieth.

The most favorable period for salt production is in the months of June, July, August and September. The mean annual production of salt is about 6 million quintals (a quintal = 220.46 pounds).
