Strategy For Each Water Demand Centre

Overall Water Balance Crocodile - Conclusions

• Overall, it appears that a water balance can be achieved without a new dam,

but• Local deficits occur and water cannot always easily be

transferred between WDCs

• Most significant interventions that will make the biggest difference in terms of reconciliation:− Water use conversions (existing applications to convert

irrigation entitlements into licences for domestic use)

− Removing invasive alien vegetation from the Kwena and Primkop Dams’ catchments

− WC/WDM

Elandshoek, Ngodwane and Kaapsehoop

Strategy For Each Water Demand Centre

• No water deficits at present

• However water supply need to be augmented in future

• The potential for augmenting water supplies through rainwater harvesting should be investigated

• An experiment on fog harvesting at Kaapsehoop can be conducted

•  Additional boreholes can also be drilled to maintain a sustainable water supply to Elandshoek and Kaapsehoop

Overall Water Balance Sabie River - Conclusions

• No dam further development possibilities on Sabie River • Most significant interventions for reconciliation:

− WC/WDM

− Water reallocation

− Groundwater development

• Water resource classification of the river could also alleviate the current and future deficits but it has to go through the full process, including full stakeholder participation.
