Scottish Infrastructure Secretary Alex Neil has written to the UK Government, offering to step in and assist if necessary.
Last month a drought in the South East was declared as the Department for Environment, Food and Rural Affairs (Defra) convened a summit of water companies, farmers and wildlife groups to discuss potential water shortages.
In the wake of that, residents in the South East were warned that water restrictions such as hosepipe bans may be needed to ensure essential public supplies are maintained throughout the summer.
But Mr Neil said that with Scotland’s “plentiful supply of water”, it was “only right” to offer help.
“The South of England is facing real issues with water supply, which look set to continue well into the future,” he said.
“With Scotland’s plentiful supply of water and superb industry expertise, it is only right we offer our assistance in the long term.”
