Groundwater

Tetra Tech Coffey’s geotechnical experts apply practical groundwater skills to help clients manage risks.

Groundwater is a precious resource and important element of any project.

Our specialist teams have experience in the prediction of groundwater inflow to open cut and underground mines, resolving the interdependence of design elements such as tailings design, the layout of the mine infrastructure, and pit scheduling and operations, as well as assessing the impacts of mine dewatering on groundwater resources, mine geotechnical designs, and the environment.

We use state-of-the-art numerical models and employ analytical methods to provide a sound basis for decision-making and support applications for approvals.
