Project Details
Location:
Lulworth Estate, Dorset
Hydro Source:
River Frome
Client's Brief:
Utilise the existing mill structures on the River Frome to create a sustainable hydro power source for the recently restored grade 2 listed historic mill. Unsuccessful attempts had previously been made to reuse an existing Armfield turbine. The Archimedes screw was recommended as an efficient and environmentally acceptable solution at this most sensitive site.
Solution Chosen:
Archimedes Screw Turbine
Plan:
PDF Plan
Site Data:
Head 1.2 m, Flow 2.0 m3/sec, Power 15 kW
Summary:
This was a very complex installation requiring temporary access bridges over the main river and a feeder stream. Extra demands were imposed by the presence of the listed mill plus the complications involved in working in a SSSI on an important migratory salmon river. The Archimedes screw turbine which was commissioned in late 2010 has operated very successfully since then. Fish recorders have been installed and the site is being used by the Game and Wildlife Conservancy Trust to study the effect of screw turbine installations on salmon and sea trout migration and spawning habits.
