Upper Fraser Hydro Power Scheme

Works Description
The Upper Fraser Hydro Power Scheme is the second highest head scheme in New Zealand at 490m and a landmark project in the power generation industry.
The project included 4,000m of high pressure GRP installation in both 1,000mm and 1,100mm, which represented an extremely technical installation of over 123 bends that required full concrete encasement. The pipe was installed through challenging countryside that required drill and blast, as well as installation of a pipe bench on the side of a slope that exceeds 60% in places. The last 950m of the penstock was high pressure steel installed on a 58% slope, and continually welded in situ with paint coatings reinstated to ensure durability of the pipeline. Our team worked diligently up the hill installing 12m sections at a time.
