Vital upgrades to begin at five metropolitan dams

Vital upgrades to begin at five metropolitan dams

11 October 2017

WaterNSW’s five metropolitan dams are due to receive a $15 million upgrade to its electrical assets, making the sites safer, more community friendly and meet contemporary standards.

Downer Group won the tender to begin the next phase of upgrades on the Upper Nepean System, which includes replacing overhead wiring and putting it underground.

Significant work will be done on the Upper Nepean System and Woronora, with Avon Dam, Nepean Dam, Cordeaux Dam, Cataract Dam and Woronora Dam to be upgraded.

The project will create approximately 15 jobs and deliver significant benefits to the local communities, providing more reliable power supplies to barbecue areas around the dams.

These upgrades represent a significant investment to ensure the five dams and recreational areas meet community and government expectations.

Construction is due to begin in November or December, and local residents and businesses will be consulted throughout the process to minimise any disruptions.

While there may be increased traffic around the sites and some local noise and dust impact during construction, traffic control and management plans will be put in place.

WaterNSW is committed to ensuring the dams meet the highest standards and this work is part of a three-year project to achieve that.

For safety purposes, access to the dam wall, picnic areas and surrounding recreation areas may be closed to the public during some of the work, but schedules will be adjusted to ensure peak times are not affected.

WaterNSW will give a minimum two weeks’ notice for any closures of the picnic and recreation areas surrounding the dams.

Information about closures to the picnic and recreation areas will also be made available on our website.

The project is due to be completed by March 2020.
