The government has plans to increase the number of reservoirs to increase water supply.
This includes discussions on adding a second reservoir in Cheddar in Somerset.
Mr Withers says this “is definitely a good thing to be doing,” and will improve “long-term resilience,” provided that we get the rainfall.
However, he added members of the public should not underestimate the impact that decisions they make about their own water usage could have.
“Even small actions, if they’re done many times by many people will make a big difference,” he said.
“Using water responsibly in the bathroom, in the kitchen and in the garden will make a difference to everybody.”
