About Mine Water Treatment

Do you know what’s in your mine water?

Looking at water through an environmental lens

Stantec offers services at every step of the process: in the evaluation, design, construction, and operation of mine water treatment plants. Our experts are well versed in the application of emerging technologies that are needed for challenging treatment requirements.

As mining clients increasingly approach mine water holistically, we have responded by taking an integrated approach to the management and treatment of mine water including mine drainage and mill process water. Cost-effective selenium removal, in particular, is one of our internationally recognized mine water treatment specialties.

As a technology-neutral company, we have no vested interest or bias towards any particular water treatment technology or vendor. This allows us to create site-specific treatment processes that are in our clients’ best interests.
