Located 620 km southeast of Algiers, the Souf Valley region is expected to confront a problem of pollution of its water tables.
These are a crucial factor for this populated region that lives mainly from growing dates. The solution to protect the environment has consisted in building large aerated lagoons to treat sewage and run-off water of all the region.
The waterproofing of those lagoons was implemented by laying 300,000 m² of the Teranap 331 TP elastomeric bitumen geomembrane.manufactured by Siplast.
