Thames Water has been told by the Environment Agency it needs to do more to fix the 630m litres of water it leaks a day before it starts taking water from the River Thames or from Wales to tackle drought problems.
The company has published its ideas for tackling climate crisis-induced droughts across London and the south-east, which include abstracting millions of litres a day from the River Thames and replacing it with treated effluent, to taking 155m litres a day from Wales.
