A water firm said it was confident it had solutions to long-term shortages and “must be more robust towards drought”, according to BBC News.
Anglian Water said it was taking “the long-term view” to ensure supplies for its 4.3 million customers.
That included building two reservoirs and reusing more sewage water.
The company, which operates across eastern England, said seawater de-salination plants were “not high in our priorities” at this time.
Anglian Water’s main region covers Bedfordshire, Cambridgeshire, Essex, Lincolnshire, Norfolk, Northamptonshire, Rutland and Suffolk, and it also supplies water to Hartlepool in northeast England.
Previously it has been said that it could have a water deficit of hundreds of millions of litres a day by the 2050s.
