Rio Tinto Aluminium (RTA) installs an emergency holding pond in front of precooked potrooms to cost $ three million. It aims to prevent runoff into tributaries surrounding the Jonquiere Complex.

According to Xuan-Lan Vu, spokesman for RTA, work will form part of the Zero Spill program put forward in recent years by the company to prevent the dispersion of pollution in case of unforeseen incidents. She explained that the precooked rooms are linked for decades to a purification system of air formed huge stacks of wood where there are industrial liquors recovering dust. “If ever there was a spill of the liquid, an emergency basin would be used to recover this water and direct them to the emergency basin. ”
The development of this basin requires digging the soil to a depth of eight meters. Part of the land used for the development of the green wall.
Ms. Vu says that since 2010, the Zero Spill program required an overall investment of $ 43 million. Work in progress should continue until the autumn.
