Strategy For Each Water Demand Centre
Water Demand Centres In The Crocodile River Catchment
Strategy For Each Water Demand Centre
• Nelspruit• White River• Karino Plaston• Nsikazi South• Matsulu• Elandshoek,
Ngodwana and Kaapsehoop
Overall Water Balance – no intervention scenario
Strategy For Each Water Demand Centre
Overall Water Balance – with interventions
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

Strategy For Each Water Demand Centre
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.
