Your challenges

Meeting today’s standards while preparing for tomorrow means tackling persistent water-related issues, including:

Managing large volumes of process water and wastewater

across remote or challenging sites.

Complying with strict environmental discharge limits

and avoiding permit violations.

Removing persistent micropollutants

heavy metals, and trace chemicals from wastewater streams.

Removing heavy metals, PFAS,

and other contaminants from tailings and effluents.

Reducing water consumption

while ensuring safe, reliable water reuse for operations.

Maintaining water quality

to protect ecosystems and communities.

Enhancing mining recovery and recover resources

from wastewater such as precious metals.

Our approach

We’re committed to giving water the value it deserves in mining and mineral processing. Our solutions are built around your operations and environmental goals, with an emphasis on the 4R strategy: Reduce, Remove, Reuse, and Recover.

  • Design and build tailored water and wastewater treatment plants for greenfield or existing sites
  • Reduce operational water demand through reuse and process optimization
  • Remove harmful contaminants and improve water quality for discharge or reuse
  • Recover valuable materials and energy from wastewater and sludge
  • Minimize your environmental footprint while ensuring regulatory compliance

Water sources and wastewater composition in mining operations

In mining operations, water comes from several sources.

The most common is groundwater, which is pumped from below the surface to support mineral extraction and processing. Increasingly, mining companies are exploring alternative water sources, such as treated wastewater or desalinated seawater, to reduce pressure on freshwater resources and improve sustainability.

Freshwater sources like rivers, lakes, and reservoirs are also used, particularly in regions where surface water is readily available. However, reliance on these sources can lead to conflicts with local communities and ecosystems, especially in water-scarce areas.

Wastewater from mining operations contains a complex mix of pollutants.

It often includes suspended solids like sand, silt, and fine mineral particles from crushing and grinding processes. Heavy metals such as arsenic, mercury, and lead can be present, depending on the mined material. Chemical residues from ore processing, including cyanide, acids, and flotation agents, are also common. In addition, salts, nutrients, PFAS and hydrocarbons may be found, requiring advanced treatment before reuse or discharge.

Our solutions

Backed by decades of water treatment experience and in-house expertise, our full-scale, modular, and mobile solutions are designed to meet your water needs from mine to refinery. Depending on your requirements and contract type (e.g., DBFMO), we integrate best-fit, proven technologies — delivered and maintained by our global teams.

Whether you’re looking to:

  • Treat and reuse process water onsite
  • Secure sustainable tailings and effluent management
  • Achieve net zero water goals
  • Reduce environmental and reputational risks

We’re here to help — because #missionwater drives every solution we deliver.
