Drought (North West)

Thursday 22nd July 2010 Written Statements

[The Secretary of State for Environment, Food and Rural Affairs (Mrs Caroline Spelman)]

The House will be aware that the first six months of 2010 have been the driest since 1929—this is partly attributable to more of our winter and spring wind coming more from the north than is usual (bringing with them the ash cloud earlier in the year), rather than the usual winds from the west which bring us much of our winter/spring rain. This has had a broad impact on the availability of water in rivers, reservoirs and canals, and on the environment and agriculture, with the lack of rain reducing grass growth and stressing other crops.

The problem has been particularly acute in the North West which has received only 60% of its average rainfall in the first half of this year. Public water supplies in this region are more reliant than most on reservoirs which are quick to replenish when it rains but also quick to empty when there is a long dry period as now. As a consequence United Utilities, the water company in the region, has encouraged consumers to be careful how they use water and on 9 July they imposed a hosepipe ban to reduce consumption.

I have been following developments closely and receive full briefing weekly from the Environment Agency, which has responsibility for managing our water resources. In addition, I recently met Philip Green, CEO at United Utilities, who updated me on the actions the company is taking to help protect supplies of water to its customers. Since the last drought in the North West in 1995-96, leakage has halved and is now operating at its economic level of leakage; this has contributed to a drop of almost a quarter in the total demand for water over the same period; United Utilities is increasing resilience of supplies through a new west to east link that is nearing completion. Other water companies are also taking positive action, as I saw for myself in a recent visit to Yorkshire Water; this company has improved resilience of its water supply since 1995-96 through creation of a network to redistribute water taken from rivers, reservoirs and groundwater across its supply area.

All water companies plan for secure supplies through their 25-year water resources management plans. These set out how a company will provide for a sustainable supply and demand balance taking into account pressures such as population growth and climate change. But that does not mean that they can avoid introducing restrictions in times of water shortage: typically they plan for restrictions once every 20 years. To plan for resources that would meet demand in any circumstances would build in significant additional costs, which would fall to their customers, and would have impacts on the environment too. And so all companies take a risk-based approach, balancing a planned level of service, to include measures such as hosepipe bans, against the costs customers are willing to pay for a secure supply.

None of us can predict what the weather will bring over the coming year and, while I am advised by the Environment Agency that no other part of England is anticipating imposing hosepipe bans at present, after such a dry six months we should all take care to protect the resources available for essential uses and not let it run to waste unnecessarily. Householders can get good advice on how to make best use of water from their water supplier, and from Waterwise (www.waterwise.org.uk).

Looking more broadly at the UK situation we must recognise that the United Kingdom has finite water resources, with some parts of England having less water per person than many hotter and drier countries. Using our water supplies wisely so that we have what we need for essential domestic and industrial purposes, while minimising the impact on the natural environment at a time of climate change and population growth is the challenge for the future. It is now 20 years since the current regulatory regime was put in place and the White Paper I plan to publish next summer will examine the options for reforming the industry to drive greater efficiency and improving the way we value and use our water resources.

I will continue to monitor the situation and will keep the House updated if there is any material change in the situation.
