Archimedean Screw Specialists
Mann Power Hydro Ltd was established in 2004 by Dave Mann. With a background in seismic and electronic engineering, Dave pursued a successful 15-year career in technical project management around the globe. On returning to the UK he took the opportunity to turn his lifelong passion for the potential of hydropower into a career – forming MannPower as an independent consultancy.
Seeking a viable hydropower solution for a Georgian watermill within an SSSI on the River Derwent in Yorkshire, MannPower’s extensive research led them to the Archimedean Screw turbine. With its fish-friendly characteristics and high efficiency rates it was perfect for the job. Dave and his company were so impressed with the benefits of the Archimedean Screw turbine that they pioneered its introduction to the UK. Dave has since been a regular speaker at British Hydropower Association conferences and seminars.
MannPower has designed and installed many dozens of schemes using machines from several of the leading manufacturers, and became the senior consultancy specialising in this technology, branching out into waterwheel projects. Now part of the TLS Group, the MannPower team continues to design and procure for new screw installations throughout the UK and Ireland as well as providing expert consultancy services and maintenance engineering services for operational hydropower schemes using screws and other technologies.
