Dam water Intake

Dam water intake
A lasting solution to preserve underground water
A programme that falls within the context of OCP’s geographical re-allocation of natural water resources, so as to meet the water needs
of the three mining sites. It consists of transferring surface water from Aït Messaoud Dam for Khouribga, and from Al Massira Dam for
Gantour (Benguérir and Youssoufia).

A large positive impact on the environment
Most of Khouribga’s industrial needs will be met by Aït Messaoud Dam. That will allow for an end to using underground
water, thus protecting the Tadla water table. Drawing water from Al Massira Dam will allow the preservation of water in the
Bahira water table.
