Saint-Gilles-Croix-de-Vie

 

The Enerplage process was an R&D project installed on the Saint-Gilles-Croix-de-Vie beach during the summer 2013.

 

The installation of this prototype proved to be successful. Aside from protecting the coastline against erosion, it provided sweet hot water for the beach showers. To achieve that, the sea water coming from this optimized Ecoplage system was desalinated by reverse osmosis.

This experiment enabled to demonstrate that a system of approximately 700meters, pumping 500m3 of sea water per hour, could autonomously produce drinkable water for a town of 12000 inhabitants. This sea water could also be used to heat about 100 apartments of 100m2 each.

This prototype also proved that it is now possible to “miniaturize” an Ecoplage system (under a 100m) and protect smaller beaches.
