Stringer’s Weir

Our latest project, due for completion in April this year, is on the River Goyt (with a head of 1.7m) in Stockport, Greater Manchester. The scheme will supply electricity to Pear Mill, an 18th Century Grade II Listed Cotton Spinning Mill. The mill, now a number of commercial units, was originally powered by a Manhattan steam engine by George Saxon & Co with rope drive transmission and will now be powered by a 100kW Archimedes Hydroscrew.

We have worked closely with the Environment Agency, Council and local stakeholders such as the Angling fraternity. The scheme has a Lariniar Fish Pass alongside it providing safe up and downstream migration for the first time since 1791 when Stringer’s Weir was built.

The turbine is 3.5m wide and over 8m in length. It will produce 281Mwh of electricity each year, which would be enough electricity to run 75 standard UK homes. The turbine will save well over 150,000 tonnes of CO2 from entering the atmosphere each year.
