# **WILSON SUMP DESIGN REDUCES PUMP MAINTENANCE COSTS**

A Canadian nickel mine had a big problem. Increased demand for nickel and other precious metals created an opportunity to ramp up production, but the mine’s current dewatering system was not up to the task. It simply lacked the capacity to handle buildup from slimes, synthetic fibers and shotcrete, and was burning out pumps regularly.

The annual costs were adding up quickly.

- Pump maintenance and repair - $600K
- Labor - $100K
- Sump scooping - 1 million+ hours
- Downtime - 1,750 hours

This operational model was unsustainable, and after crunching the numbers, it was clear the existing dewatering system had to be improved. Download the case study to learn more about the birth of the Wilson Sump design, and GPM’s role in revolutionizing mine dewatering.
