7 Potential strategies (1) Supply side strategies:  Planning: oRegional water resource planning oLocal water resource management and monitoring system oConjunctive use of surface and groundwater  Relief measures: oStandby relief under critical conditions eg Water tankers oDrought relief and aid funding  Technologies: oArtificial groundwater recharge oRainwater harvesting oDesalination oRainfall enhancement  Reduction of leaks programme  Removal of alien invasives

8 Potential strategies (2) Demand side strategies:  Water restrictions  Tariff structures -eg. Block tariffs  Education programmes  Re use of grey water  Reduction of leaks programme  Sanitation options: o Dry sanitation systems o Saline water for toilets o Dual flush toilets

15 Screening criteria for assessing the strategies 1. Additional yield / saving How will the intervention impact on water supply through additional yield and/or savings? 2. Technology required Is the technology for the intervention readily available? 3. Additional capital expenditure Will the intervention require additional capital expenditure? 4. Additional running costs Will the intervention incur additional running costs? 5. Local employment To what extent will the intervention impact on job creation? 6. Local capacity to implement What level is the institutional capacity currently at with respect to the intervention? 7. Acceptability to local community What is the consumer acceptability of this intervention in terms of additional cost to them and convenience? 8. Impact on local water resources What impact will the intervention have on the water resources and the environment in the area? 9. Long term applicability What is the period of impact of the intervention? (short - long term)
