A few notes:
- Leakages of water also mean leakages of energy, but they are missed if they are unbilled
- This diagram does not include energy used by customers (e.g., heating water), which is significant
- Energy usage varies with standards for treatment or sources of water. Vancouver gets gravity-delivered snowmelt while Riyadh depends on desalinated water piped from 500km away
- Water and energy accounting does not lead to good management, but managers can use this information to improve efficiency
