It’s a big challenge, because the aquifers (from which we source our groundwater) and rivers (which feed into our surface water reservoirs), need rain to replenish them.
We are taking a number of steps to protect our supplies but we all need to do our bit to save water, which is why we've lauched a campaign encouraging everyone to Drop 20 litres of water a day.
Even in a good year the East of England is the driest part of the UK. The fact we did not need a hosepipe ban last summer was down to continuous investment in our network and to the fact our customers understood the importance of saving water.
