HydroWorks has been involved in the design of water turbines and pumps since 2001.

RikHothersallOur founder and chief engineer, Rik Hothersall, has designed turbomachinery for over 25 years. His experience ranges from a tiny 5 kW cross flow turbine operating on a mission station in Papua New Guinea, to a 100 MW pump turbine runner at the Cruachan Power Station in Scotland.

HydroWorks operates in close collaboration with our partners to design and manufacture state of the art hydro solutions with world leading efficiencies. One such product is the InRace Generator, a high specific speed generic turbine that operates on heads between 4 and 11 m.

Our first Francis Runner was installed at Mangorei power station, New Plymouth in 2003. The 1.8 MW runner met its performance predictions and is operating well. Since delivering the Mangorei runner HydroWorks has been involved in the design, manufacture, and installation of more than 30 hydro projects around Australasia. We have profiled a few key projects on this site.
