Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate his Department has made of the level of national water storage capacity.

The Environment Agency’s National System Simulation Model, which includes 90% of England’s supply system, shows the current national total storage capacity of 2.03 billion cubic metres for public water use.

Havant Thicket reservoir is currently under construction and a further 9 new reservoirs are planned by water companies. These are expected to provide an additional water supply of over 700million litres per day by 2050.
