According to Bluefield Research, there are three trends driving growth in water for mining:

1) Nearly 50 percent, or US$223 billion, of planed hard-rock investment globally is slated for regions with medium-to-high water stress.

2) New regulations on water supply, wastewater treatment, and acid mine drainage in key markets are forcing miners to adopt solutions.
