Andy Shaw, the company’s head of water production, treatment and energy, made clear there were no current plans to impose a late ban, but he hinted this could change if it “remains considerably dry”.
Appealing to customers to play their part in protecting supplies, he said: “We are expecting a drier spell to end September, so it is important people continue to take steps to review their water usage and make any changes to water use where they can.”
Last week, levels rose for the first time since June following recent rainfall – but not by enough.
Across Yorkshire, reservoirs are at 47.6% capacity – significantly below the 68.7% average for this point of the year.
This time last year, when the region was still under a hosepipe ban following the driest spring in more than 100 years, they were at 45.6%.
Shaw credited his team for their work in avoiding having to impose restrictions.
“Our teams have worked around the clock to manage the water supply to ensure all our customers have the water they need, without the need for any usage restrictions.
