Householders in parts of England are to see hosepipe bans come into force as months of dry conditions push the country towards drought.
After two water companies announced restrictions, others are warning they may need to follow suit if the sustained dry weather and high demand continues.
As utilities urge customers to use water wisely even without restrictions, for example by ditching the hosepipe for the garden and cleaning cars, there are warnings the UK must manage water demand for a changing climate.
