People living in Cornwall will be given money off their water bills if one of the Duchy’s reservoirs can return to 30% full by the end of the year.

South West Water said it would give customers £30 off their bills if they can hit the target at Colliford Reservoir, which currently is only 17% full.

It is asking customers to make changes to their water habits and reduce usage to achieve the improved level, with Cornwall still under a hosepipe ban.

The water company wants to see people aiming to save ten litres of water every day, with suggestions including reducing the amount of time they shower for, and turning off taps when they are brushing their teeth.

The "Stop the Drop" incentive is only available for customers within Cornwall, as reservoir levels remain low here.

Devon has seen water levels return much more quickly, with average levels across the border said to be almost three times higher than at Colliford.

South West Water is hoping the “collective might” of Cornwall will be able to achieve the target by the end of the year.

Laura Flowerdew, from the water company, said engineers had been working “around the clock” to get new supplies set up, find and fix leaks, and help customers and businesses reduce how much water they use.

She told the BBC: “However, in Cornwall reservoir levels remain low. That is why we are asking everyone to help Stop The Drop, so we can restore reservoir reserves, ensuring we have enough water today and into next year.”
