WaND Briefing Note 28 Revised Options for UK Domestic Water Reduction - A Review

Demand pressure on UK water supplies is expected to increase in the next 20 years driven by increasing population, new housing development and reducing household size. Regionally and at town level migration will also affect demand particularly in the South-East which is forecast to have a larger than average growth in population and house building.

The water demand moderating trends that are considered to have the greatest effect on UK consumption, in approximate order, are:

1. Metering

2. Low flush toilets

3. Normal showers

4. Efficient washing machines

5. Dishwashers

6. Cistern displacement devices (in existing homes with large cisterns)

7. Water efficient gardening measures can play an important role in reducing demand during critical drought periods
