The capital is "at risk of major flooding" unless something is done to support the over-capacity sewer system, according to a new report.
The new research supported by the Major of London, Thames Water, the Environment Agency and London Councils calls for the capital's public spaces to be transformed into green areas which will help absorb surface water after rainfall.
17% of permeable ground has been lost in London over the past 40 years as homeowners chose to cover their previously green lawns with concrete. This means that water which used to be absorbed is now directed towards sewers which are unable to cope with the strain.
