Mine Water Treatment | Veolia Water Technologies
Veolia ensures overflow compliance and water treatment, but we also look at the overall wastewater strategy. In particular, Veolia investigates opportunities to treat wastewater at source point to reduce the load going to tailings and we see tailings as an opportunity for water and metals recovery to make the most from the available resources.
