I cannot give my noble friend an answer to the specific question he asks, but the storage of water when it is available is critical. It was shocking to realise that we had not built a reservoir in the country for 30 years; we are now planning new reservoirs to store water. Also, during the passage of the Planning and Infrastructure Act we talked about on-farm storage, for example; it is perfectly possible for farmers to develop storage on their own land so that they can keep water when it is plentiful for the times when it is not.

My Lords, to continue from the previous question, large underground attenuation tanks are often used in residential developments as their answer to sustainable drainage. Can the Minister tell us what consideration has been given for the water that is stored in these tanks to be used as grey water for local people to use during times of drought?

I know that my colleagues in Defra are giving a great deal of thought to the provision of water—both clean water and water for other purposes—and they have established the Water Delivery Taskforce to make sure that water companies deliver on their planned investments to provide water and wastewater capacity. The Government have worked hard to secure £104 billion of private sector investment into the water sector over the next five years so that we can upgrade ageing pipes, sewage treatment works and so on, and in partnership with water companies, investors and communities we will introduce a new water reform Bill to modernise the entire system. The issues that the noble Baroness raises are really important. We need to be using all the water that we have access to, particularly in dry areas of the country—I live in the east of England, one of the driest areas in our country—and we need to make sure that we are making the best use of any rainfall we have. The Government are working closely with the industry to make sure we do just that.
