Record-breaking rainfall in April has helped to boost Yorkshire’s water stocks by 12 billion litres.
Yorkshire Water’s reservoir levels have swelled from 91 per cent to 98 per cent full, with some full to overflowing.
But it has warned its boreholes will take much longer to replenish.
Ian Stevens, water resources manager at Yorkshire Water, said: “It’s worth remembering that the last 20 months have been the driest on record, with groundwater supplies really suffering as a consequence.
“Borehole supplies always take much longer than reservoirs to replenish, so whilst we have seen them recover slightly over the last four weeks, there’s still a long way to go before these are at anything like healthy levels.
“We’re continuing to work hard to manage and balance stocks across the region, with our message to customers remaining the same as ever: Only use what you need, and be sensible around how you use what is a very precious resource.”
