The work at Wayoh involves cleaning the spillway by removing all the vegetation and jet-washing the face of the stonework before pressure-grouting the original stone sets to secure the spillway and prevent it declining further.
Andrew Baron, a senior manager with United Utilities, says the work is key to improving reservoir safety. He said: “This is something we hold in the highest regard. By clearing and pressure-pointing the overflow channels, the reservoirs will be fit to tackle the challenges we all face from an ever-changing climate, in particular flash floods. It will also drastically improve the aesthetics of the reservoirs.”
The renovations at Wayoh will be finished by Christmas. A second team from Hardys has already begun similar work at Quarry Hill, in Cumbria, and engineers will then move onto Borrans, Horlock and Pennington reservoirs, all of them also in Cumbria. The programme will be completed by the middle of 2015.
Andrew Baron says he’s delighted with the standard of the work. “They’re more than living up to the recommendations we received and they’re delivering a fantastic job on site, helping us keep our assets in top condition”.
