Water Sources and Technologies
Surface water
- Rainfall trends
- Water storage weekly status map and state of dams data
- Water quality interactive maps:
- Wetlands:
- Wetland is a land area that is saturated with water, either permanently or seasonally.
- According to the Forests Act (no 122 of 1984), no one may drain and/or cultivate any wetland, or do so within ten metres of the flood area of the wetland, without a permit. It is also unlikely that a permit will be granted to drain a wetland which is permanently saturated during normal rainfall season.
