Mugga reservoir is approximately 60 years old and is in the Australian Capital Territory. It is a 45 megalitre water reservoir that supplies water to homes, schools and businesses. Additionally, the reservoir acts as a balancing tank for the Woden area.

Due to the age of the reservoir, Icon Water engaged Duratec to provide remedial works that would ensure the reservoir continues to provide drinking water safely and to the high-quality standard required, long into the future.

  • Isolation and removal of redundant services and reinstatement of control panel to new position.
