How could illegal mining activity in Roodepoort affect the Department of Water and Sanitation?

Possible What happens if… A possibility worth considering, not a forecast.

Illegal mining in Roodepoort strains water resources managed by DWS Illegal miners, known as zama zamas, are extracting water from local sources in Roodepoort for panning and processing gold. This activity places direct operational strain on the local water supply, which is managed by the Department of Water and Sanitation. The reports detail instances where miners took water from 25,000-litre tanks for these purposes, indicating a localized but persistent depletion of resources. This illegal extraction contributes to the broader issue of resource strain in the region.

The facts so far

As reported. Each one links to where it comes from.

  • Illegal miners, called zama zamas, arrived in Roodepoort to dig for gold.aol.co.uk
  • Miners took water for panning and processing from a charity's two 25,000-litre water tanks.aol.co.uk
  • Researchers estimate the number of illegal miners in the tens of thousands.aol.co.uk
  • The high price of gold is cited as a dynamic driving illegal mining.aol.co.uk

Why it matters

Illegal mining poses a significant threat to local infrastructure and resource stability in the Gauteng province. The activity is driven by factors including the high price of gold, poverty, and unemployment, leading to the exploitation of voids left by derelict and ownerless mines. The mining minister reported that there were 6,100 derelict and ownerless mines and 1,170 unsafe mine openings in 2025.

This illegal activity strains public resources and complicates the mandate of water regulators like the Department of Water and Sanitation. While some experts argue that formal industrial mining is the biggest culprit for sinkholes, the intense mining by zama zamas in areas with residual gold definitely causes structural collapse, adding pressure to municipal services.

What we don't know yet

  • What is the current capacity of the Department of Water and Sanitation to manage illegal water extraction in Roodepoort?
  • How effective are current police operations in curbing the scale of illegal mining activity?

What would change this answer

The price of gold continues to soarThe incentive for zama zamas to engage in illegal mining and water extraction will increase, intensifying the strain on water resources.
The city government increases its efforts to seal abandoned mine shaftsThe voids left in the earth will be reduced, potentially limiting the opportunities for illegal miners and reducing water extraction.
