Work to an underground tunnel which runs under one of Yorkshire’s oldest reservoir embankments, at Ogden reservoir, is now complete.
Engineering specialists, Mott MacDonald Bentley, had been working since February to seal the 140m long tunnel which runs beneath the embankment, between the reservoir valve tower and the nearby beck.
In addition to the tunnel improvements, the company strengthened the reservoir embankment through the addition of 3,500 tonnes of earth to the downstream face.
As well as providing water for supply to Mixenden Reservoir, Ogden Reservoir also serves to maintain compensation flow to the downstream beck, to ensure the watercourse remains healthy throughout the year. This is achieved via the underground pipe located within the tunnel, which serves to transport water from the reservoir to the local beck, which in turn feeds the nearby river.
Tom Cochrane, Yorkshire Water Project Manager, said: “This ensures Ogden continues to effectively perform its primary role of topping up local water courses in times of need.
“We’d like to thank local residents and visitors to the reservoir for their patience.”
