D6 Water Storage Dam

Project Overview

Ertech was contracted to expand the water storage dam to 6GL storage capacity to provide long term water security to mitigate the risk of running out of water. The project involved the construction of a water storage dam using locally sourced construction materials.

The water will be pumped into the D6 Dam from the Hotham River Pump Station No 1 and 2.
