One of the UK’s largest water companies is considering shipping supplies from Norway to the UK.
Southern Water said the idea was a “last-resort contingency measure” in case of extreme droughts in the early 2030s.
Up to 45 million litres per day could be brought to the UK in tankers under the proposals.
The Financial Times, which first reported the potential move, said the water would come from fjords in the Scandinavian country.
It comes as fears grow over the future of water services in the UK following droughts in the summer of 2022 when some areas of the country came close to running out of supplies.
The Financial Times said Southern Water was in “early-stage” talks with Extreme Drought Resilience Service, a private UK company that supplies water by sea tanker.
The firm would pay for the measure out of customers’ bills, according to the report.
Southern Water, which covers Hampshire, Kent, East and West Sussex, and the Isle of Wight, currently gets its supplies from groundwater and rare chalk streams.
However, the Environment Agency (EA) has urged the firm to reduce its reliance on such sources amid concerns over the environmental impact and fears they could make the risk of droughts worse.
‘Costly and carbon-intensive’
Water firms have come under growing criticism in recent years over sewage spills and rising bills, with households facing an average increase of 21% over the next five years.
Companies have also been urged to improve their infrastructure to help supplies. Currently around a fifth of water running through pipes is lost to leaks, according to regulator Ofwat.
And a report by the EA earlier this year found that Southern Water, along with Anglian Water, Thames Water and Yorkshire Water, was responsible for more than 90% of serious pollution incidents.
Following criticism over sewage discharges, Southern Water’s chief executive Lawrence Gosden blamed “too much rain” in 2023 for the problem during an interview with ITV News.

The company said it was facing a shortfall of 166 million litres per day in Hampshire alone during future droughts.
But the firm said it was already undertaking other measures to address the problem, including by building the UK’s first new reservoir in more than three decades in Havant Thicket.
However, Greenpeace UK’s chief scientist Dr Doug Parr criticised the Norway proposal and said the firm should focus more on addressing issues domestically.
“Tankering in huge quantities of water from Norway will inevitably be a costly and carbon-intensive alternative to that of doing a better job with the water resources that are available in a rainy country like the UK,” he said.
He added: “Despite the obvious failings of planning, water companies need to start thinking of potable fresh water as a precious and finite resource, and plan to start treating it as such.”

From 2022: How can we protect ourselves from water crisis?
Tim McMahon, Southern Water’s managing director for water, said: “We put less water into supply now than we did 30 years ago and measures like reducing leakage have enabled us to keep pace so far with population growth and climate change.
“As we work to take less water from our chalk streams and build new reservoirs like Havant Thicket in Hampshire, we need a range of options to help protect the environment while this infrastructure comes online.”
Mr McMahon added: “Importing water would be a last resort contingency measure that would only be used for a short period in the event of an extreme drought emergency in the early 2030s – something considerably worse than the drought of 1976.
“We’re committed to continuing to work with our regulators on developing the right solutions to meet the challenge of water scarcity, while protecting the environment.”
