LONDON (Reuters) - Cities need to review their drainage systems in the wake of this summer’s floods to cope with the possibility of more extreme weather due to climate change, a report said on Friday.
Britain has suffered its worst flooding in 60 years this summer, killing at least nine people, delaying harvests and causing well over 2 billion pounds of damage to homes and businesses.
“Nationally, we suggest that for urban drainage the level of 1 in 30 years should be reviewed as a minimum, and that some additional capacity should be factored in for possible climate change,” said a report into the June floods in Hull, commissioned by Hull City Council.
Hull was one of the worst-hit areas as waters swamped towns and villages across central and northern England during the first wave of flooding.
“In June 2007, Hull has experienced two events of magnitude greater than 1 in 30 years, and predictions of the effects of climate change suggest that extreme events will become more common in the future,” said the report. “Hull should have additional levels of protection.”
Kelda’s Yorkshire Water, which manages Hull’s drainage system, said it would respond to the report later on Friday.
Over 7,200 homes and 1,300 businesses were damaged in Hull during its wettest June since 1882.
The low-lying city relies on a system of pumps to keep flooding at bay, and the report questioned whether the existing capacity was capable of handling a 1 in 30 year storm.
