National Trust Hydro-electric - Quarry Bank Mill

Atkinson Peck are currently acting as Clients Civil Engineering Project Supervisor for a joint venture between the National Trust and the Environment Agency to provide a hydro-electric power scheme and fish pass downstream from Quarry Bank Mills historic weir on the River Bollin.

Since 1784 when the Mill was founded by Samuel Greg, the weir was used to harness the waterpower of the River Bollin, driving a huge water wheel which in turn powered the spinning and weaving machines. With the new scheme, generation of water-powered energy will be taken to a new level through the use of a Kaplan turbine installed 30 metres downstream from the weir. This propeller-type turbine with adjustable blades will generate enough electricity to meet 55% of Quarry Bank’s on-site energy requirements.

Previously inhibited by numerous weirs constructed during the North Wests industrial past; the migration of fish such as salmon or trout to the upper Bollin will again be possible thanks to a fish pass (or ladder) which is being constructed alongside the turbine. It is hoped that significant improvements in the water quality of the Mersey Basin will lead to re-colonisation of locally extinct species.

The hydropower scheme and fish pass will be fully operational in the spring, when we will hope to share pictures of the finished project.
