Water in the UK – rights and responsibilities Claire Ashton
What do we use water for? • Domestic purposes(personal hygiene, cooking, cleaning) • UK industry and services • UK agriculture • “Virtual water” in imported goods (62% of UK total water use (WWF 2012))
How much water do we use? Activity Litres 40 Five-minute shower 80 Bath 8 Flushing toilet 10-25 Dishwasher 65 Washing machine Eating a tomato 13 Eating an apple 70 Drinking a cup of coffee 280 Eating a hamburger 2400 [statistics from Ofwat, Uswitch and RuSource]
How much water do we use? • Only 38% of the UK's total water use comes from its own resources; the rest depends on the water systems of other countries, some of which are already facing serious shortages (WWF 2012). • Average household water use for washing and drinking in the UK is about 150 litres a person daily, but we consume about 30 times as much in "virtual water", used in the production of imported food and textiles.

Discussion questions • How do we balance environmental issues with supply security (reduce leakage, build new reservoirs, desalination)? • How do we reduce our use of “virtual water”? • Is domestic water a right or should we pay for what we use (metering)? • Should we move to a dual supply system of drinking water and grey water?
