There is a history of milling on the Gelvin River and this project combines the location of an old weir with modern pipe technology to develop a fall of 38 meters.
This hydro project has been constructed in a river with the highest possible environmental protection, it is an SAC for salmon. This was a significant consideration through out the design, planning application and construction stages of the project.
HydroNI were responsible for the feasibility study, planning application, construction standard drawings, project management of the construction of the project, installation and commission of all equipment.
