Supporting SIBA in the design of their second Sediment Management Unit

The natural site of the Arcachon basin is subject to sediment siltation, causing problems of hindrance to the navigability of oyster farmers, fishermen and boaters.

 

Our teams are supporting the Syndicat Intercommunal du Bassin d'Arcachon, in charge of dredging sediments from ports and channels, on the creation of its first onshore sediment storage and management unit.

 

The objective: to maintain the water levels necessary for users and to make waterways safer

 

Including their recovery in a context of biodiversity preservation, the sediments resulting from these operations are transported to settling and storage basins, then evacuated from the site once dry. These settling and storage basins have recently been categorised as Classified Facilities for the Protection of the Environment.

 

The storage and processing process required the creation of:

3

drip basins

with a total capacity of 11,600 m³ 

3

storage basins

with a total capacity of 9,500 m³

5

water collection lagoons

with a total capacity of 10,500 m³

1

covered work area

on 2,000 m²

A project combining an industrial process with the development of a specific biodiversity:

  • Promote the maintenance and/or development of natural fauna and flora
  • Assess the attractiveness of the area after the work and during operation
  • Creating a disturb-free space over a long period of the year has been achieved.
