Cape Sicié, France. Revitalizing a marine environment: the Remora project

In 1980s Toulon,  the main sewage system fed directly into the sea, leading inevitably to massive degradation of the immediate marine environment.

In the face of this disaster in 1997 Veolia designed and built the Amphitria wastewater plant that it manages to this day on behalf of the municipality. The marine environment gradually became less polluted but biodiversity in the zone remained highly compromised. In 2010, Veolia’s local teams came up with the idea of sinking two 360-square-meter artificial reefs to promote the return of marine species that formerly made their home in the waters of Cape Sicié. The Remora project aimed to deliver three objectives for marine life: provide a home, food and a chance to reproduce.

In 2016 the first positive results were seen and it appeared that the submerged reefs were indeed attracting numerous fish, crustaceans and echinoderms (starfish, sea urchins, etc.). Pioneering species started to repopulate the area. Led by Veolia’s Mediterranean team with technical and financial support from the Rhone-Mediterranean-Corsica river basin authority and the Veolia Foundation, Remora is a great example of a project designed to promote biodiversity.
