All the walls of the SETEC Vengeron basins have been completed. Concreting has gone well, including in curved areas. The prestressing cables in the walls are all under tension.

Work over the next few months will include concreting the final ancillary elements, backfilling the basins with gravel of varying grain size to ensure the filter function, backfilling and landscaping.
