Lake Waitaki is created by the Waitaki Dam, a 36m high spill weir dam built between 1928 and 1934. The Waitaki power station has an installed capacity of 105MW. Waitaki was the last dams built in New Zealand with excavation done with pick and shovel, not heavy machinery.
As part of a major upgrade to Meridian Energy's asset, the original wing walls of the spillway required strengthening. Geovert worked closely with the engineers at Damwatch during the development of the design on a restricted access construction a methodology to ensure the anchors were installed and tested to BS8081 standards.
