The water of the lagoon, which, without equal, gives Venice charm and wonder, undermines its survival.

To save Venice and the treasures of art and culture, which the lagoon treasure chest has jealously guarded, it is necessary to regulate the water level in the lagoon.

The Sa.Ve. project to conserve Venice includes the systems mentioned below.

1 Patented system, for the regulation of the water level of the lagoon, which limits the excursion of the water level in the lagoon within normal physiological limits, even when the sea level reaches heights for which, in the absence of protection, the lagoon settlements, including Venice , would be at least partially submerged by high water.

Navigation, through the three port inlets, is always possible, it takes place without hindrance when the water level in Venice is normal and with a compensation system when the sea level exceeds the normal threshold and the phenomenon of high water occurs in Venice.

2 Patented system for change of lagoon water, which can be associated and integrated with the water level regulation system.

During the entire calendar year and in particular in the periods in which the sea level exceeds a safety threshold and the lagoon is protected, the hydraulic system exchanges the water of the lagoon in an adequate measure, in an almost physiologically natural way, i.e. with flows daily of water from the sea to the lagoon and vice versa which are in phase and synchronous with the tide in the open sea.

The lagoon water exchange system works totally and exclusively with energy produced by the tides.

3 Patented system for the protection of banks and foundations to avoid erosion due to the movement of water against them and to avoid the unwanted deposit of sediments in the rivlets and canals of the lagoon.

4 Patented system for production and storage renewable energy, which can also stand alone or can be associated with the Sa.Ve. .

During the entire calendar year, both when the lagoon is protected, due to the occurrence of high water in Venice, and when the inlets are completely free from protection, the energy production and storage system accumulates potential mechanical energy, deriving from energy produced by the tides in the open sea and from wind energy produced by particular patented wind turbines for lake and lagoon environments.
