Hydrology & Hydrogeology

We deliver mine water management services to established and new mine sites all over the globe. Our team has a great depth of experience, working on sites in Australia, Africa, Europe, Russia and other locations around the world.

CSA Global doesn’t believe in offering a ‘standard’ service, because every site faces its own specific set of challenges. This is why our team of hydrogeologists, hydrologists and engineers tailors a solution based on the key issues facing your mine site.

We draw on decades of mining, hydrogeology, hydrology and geotechnical expertise to develop efficient and practical solutions for your mine’s water management.

Complete mine water management

We handle all elements of your mine water management – from collecting initial pre-mining baseline data to ensuring regulatory compliance for both surface water and groundwater aspects.

Our team also assists with:

  • Sourcing and supervising suitable contractors, who perform drilling, test pumping, water treatment and specialised monitoring services.
  • Demonstrating that a sustainable water supply exists for the life of the mine, and that dewatering is manageable.
  • Performing research and checks to ensure you have an effective, efficient and fully operations mine water management system.
  • Working efficiently to ensure milestones and budgets are met.
  • For more detail on the entire process, please talk to us.

How we support you

Our specialist team has the capabilities to assist any open cut or underground mine with solving its surface water or groundwater issues.

We work in a wide range of climatic and hydrogeological environments – from extreme temperatures (both hot and cold) to arid deserts and tropical rainforests.
