Hundreds of UK power substations and water treatment plants are potentially at risk from flooding, a confidential government study suggests.Hundreds of UK power substations and water treatment plants are potentially at risk from flooding, a confidential government study suggests.

The study finds "the risks posed by natural hazards are already rising and are predicted to rise further". Yorkshire and Humberside, the Midlands and Gloucestershire were among the worst affected areas after heavy rain.
While work to boost resilience is ongoing, the report calls on companies, regulators and ministers to act. And a separate study suggests that the UK is entering a "flood-rich" period where more flooding is likely.
The report warns that "there are likely to be hundreds of sites at the highest levels of criticality". The government report calls on companies, regulators and ministers to act.

What alarms officials is the potential impact on the normal functioning of society - and the speed with which last summer's rainstorms led to flash flooding. The summer floods saw about 13 people killed and 44,600 homes and 7,100 businesses flooded, with the damage caused costing £3bn.

Meanwhile, Professor Stuart Lane, of Durham University's new Institute of Hazard and Risk, has published a report in the academic journal Geography, which suggests the UK will experience more floods in future.
He said: "We have also not been good at recognising just how flood-prone we can be.
"More than three-quarters of our flood records start in the flood-poor period that begins in the 1960s.
"This matters because we set our flood protection in terms of return periods - the average number of years between floods of a given size.
"We have probably under-estimated the frequency of flooding, which is now happening, as it did before the 1960s, much more often than we are used to."
And the Commons Environment Select Committee has said the infrastructure to deal with the same scale of flooding seen last year is in "an unclear and chaotic state".
The nation's current flood defences are focused almost entirely on river and coastal flooding, but about two thirds of last summer's floods were caused by surface water, often following heavy rainfall.
Learn lessons
MPs said there was no organisation with overall responsibility for surface water flooding at a national or local level, no-one was responsible for issuing flood warnings and it was unclear who had responsibility for overflowing drains.
Ministers, the committee added, had repeatedly suggested that the £800m a year for flood management by 2010/2011 would allow the government to deal effectively with future cases of flooding.
But a report has warned the settlement for flood defences made under the Comprehensive Spending Review was "far less impressive under close analysis".
Environment Secretary Hilary Benn told the BBC that the government needed to "learn the lessons from the summer" and that the issue of green belt land being concreted over needed to be dealt with.
He said: "That's a product of development in our society.
"One of the things that the terrible floods of last summer has taught all of us is we need to think about the consequences of that.
"That's why we're changing the rule on front gardens, that's why we're reviewing the ability of new developments to automatically connect to the public sewerage system, because we need to think about where the water is going to go."
