Warragamba Dam

The Warragamba Dam created one of the largest man-made lakes in the world, with an area of 75 square kilometres. The lake now supplies 80% of Sydney’s drinking water. Access to the dam itself and the surrounding bushland is restricted for safety reasons and to protect water quality, yet people have always been fascinated by this massive 2.5 million tonne structure.

In 2009, a new Visitors' Centre was opened to satisfy that public curiosity. We were engaged as the electrical contractors for the Visitor Centre and the new Workshop for the Sydney Water Catchment Authority.

In proportion with the epic scale of the dam itself, the job we had to do involved some impressive numbers: we installed over 5 kms of service trenching, conduits and cabling to feed power to the new buildings. The power required to run all the facilities, including interactive displays, signage, lighting and climate control meant that we were commissioned to install a new sub-station and generator. The budget for this 18 month project was $2 million.
