4 litres (3% are used for drinking), 30% (45l) are flushed down the toilet.
Best practice use would fall below 30m3/person/year (80 litres/person/day).
Effective rainfall and licensed abstraction comparison points towards potential scarcity of water in southern areas of UK in future (Ecohomes).
Less water use would reduce costs associated with waste water treatment.
Measures to achieve this would include:
- Take more showers than baths.
- Choose water saving appliances (WCs, water taps, showers, washing machines).
- Collect rainwater for watering garden/ use for toilet flushing.
