IB ESS 4.2.6 Domestic water conservation
Practise using domestic water data to calculate remaining supply and explain how households and governments reduce demand per person.
How this is tested
- calculate water left for other uses after mines, towns or plants meet stated demand
- outline domestic conservation actions such as metering, grey-water reuse or rationing
- suggest policy tools, including pricing or education, that reduce household water consumption
