Waitaki Dam

The Waitaki Dam is one of eight hydroelectric power stations which form the Waitaki hydroelectric scheme on the Waitaki River in the Canterbury Region of New Zealand. The dam was the first of three to be built on the Waitaki River and was constructed without earthmoving machinery; over half a million cubic metres of material was excavated, almost entirely by pick-and-shovel. The Waitaki Dam's construction was followed by the development of Aviemore Dam and Benmore Dam, and importantly, every dam built in New Zealand since the Waitaki has benefited from lessons learned during its construction. The Waitaki Dam is unique; its construction lead to the germination of one of the world's first social welfare systems. Built during the Great Depression, the Waitaki Dam attempted to soak up unemployment as part of the Government's make work scheme and saw the trial of medical welfare where an individual could build a satisfactory life without fear of the inability to cope with age or poverty. Initial construction of the dam began in 1928 and was completed in 1934 with full power being delivered from two 15 MW generators on 1 January 1935. Three additional generators were added between 1940 and 1949 and a further two generators were added between 1952 and 1954. With seven generators each delivering 15 MW, the total generative output of the Waitaki Dam is 105 MW.
