Building the Wainuiomata reservoir

Building the Wainuiomata reservoir

The headwaters of the Orongorongo and Wainuiomata rivers are a vital part of Wellington’s water supply. In the late 19th century a dam to supply Wellington was built on the upper Wainuiomata. By 1918 this was inadequate. To increase the supply, the headwaters of the Orongorongo were tunnelled to the Wainuiomata dam.
