 Application Details

The raw water ponds are the water storage facility for the entire Sadiola complex. The ponds receive water from the Senegal River via a pipeline roughly 70km long.

Lining was installed to 2 ponds.  The 1,5 mm thick material was installed on the floor whilst the 2,0 mm thick material was installed on the sidewalls.

The lining installation took place in Mali’s rainy season and the constant storms and heavy winds posed challenging problems. The site conditions were relatively arduous as Sadiola was the first mine opened in the area.

The local labour was completely unskilled and some of the machinery such as grinders caused the locals to flee in fear.

Despite the trying conditions, the lining project was completed on time and to the satisfaction of the client and engineers.   

Engineered Linings revisited the site in 2001 and found the lining to still be in perfect condition, five years later.
