Spill Containment and Bunding for Gold-Mine Solar Pump Sites in Botswana
Introduction
A leak at a mine is more than a puddle—it is process water, fuel or reagent that should never reach the ground. This article covers spill containment and bunding for gold-mine solar pump sites, using Botswana’s goldfields—the Tuli and Motloutse belts—as the worked example, written by the solar-pumping specialists at KINBO. A bund around the pump house and stores pairs with the hydraulic discipline of our pipe-and-fittings guide.

Why Containment Matters
- Catch the leak—a bund holds a burst hose or seal so process water stays on the pad, not in the veld.
- Protect the source—containment keeps the pump area from contaminating nearby ground or streams.
- Meet rules—our TCO guide counts a containment failure as a real cost, not a footnote.
- Speed recovery—our maintenance guide plans the cleanup and swap.
Botswana Goldfield Conditions
Botswana’s dry gold belts sit beside fragile Kalahari soils, so a single spill lingers and spreads. Our dust-and-heat guide and pipe-and-fittings guide frame the duties; here the prize is a site that contains its own mistakes.
Designing Bunding, Step-by-Step
- Capture the volume—from the sizing, size the bund to the largest likely release, not just the daily tank.
- Ring the pump house—a low wall or lip around the pump and controller keeps leaks in.
- Bund the stores—fuel and reagent drums sit inside their own contained sump per our pipe-and-fittings guide site layout.
- Floor it—an impermeable, sealed base stops seepage through the pad.
- Add drainage—a contained sump and pump-back line return captured water instead of washing it away.
- Inspect it—checks fold into our maintenance guide routine.
Bunded vs Unbunded Site
| Aspect | Bunded | Unbunded |
|---|---|---|
| Leak outcome | Contained, recovered | Spreads, lost |
| Compliance | Meets duty | At risk |
| Recovery | Pump-back line | Cleanup cost |
For the cost view, our TCO guide weighs bund cost against spill liability.
Frequently Asked Questions
How big should the bund be?
Big enough for the largest single release—pump house plus day tank—from the sizing, not just routine flow.
What goes inside it?
The pump, controller and any fuel or reagent drums, per our pipe-and-fittings guide.
Does it help compliance?
Yes—containment is what inspectors look for, and our TCO guide treats a spill as a balance-sheet event.
