Woronora Dam closed to public for vital upgrades

Woronora Dam closed to public for vital upgrades

24 September 2018

Woronora Dam will be closed to the public on week days until the end of the year as part of the Metropolitan Dams Electrical Upgrade Project.

There will be full park closures at Woronora Dam during weekdays, but it will re-open on weekends. Closure of the park is necessary to ensure public safety during the work, and signage will be in place where needed.

Woronora Dam is located about 56km south west of the CBD and is the second most visited dam in Sydney, behind Warragamba Dam.

The work at Woronora Dam forms part of a wider project to upgrade the electrical assets in five of WaterNSW’s dams in the Upper Nepean system.

Downer won the tender to undertake the upgrades at Woronora, Avon, Nepean, Cordeaux and Cataract dams and at the Nepean/Avon Tunnel. These dams supply up to 30% of Sydney’s drinking water and are vital in ensuring high quality water is supplied to Sydney and the Illawarra.

The project across the five dams involves:

  • Upgrading electrical, control, instrumentation and communication assets and relocating electrical lines underground.
  • Improving the reliability of electrical services to all equipment and facilities onsite including picnic areas.
  • Improving safety during bushfires.

Access to the dam wall and surrounding recreation areas may be restricted at all five dams when construction work is taking place at the respective sites. There may be increased traffic in and around the work sites and some localised noise and dust impacts.

WaterNSW is keeping residents, local businesses and the wider community informed of any potential disruptions and is striving to minimise impacts. WaterNSW will provide a minimum of two weeks’ notice before the closure of any picnic areas.

For more information on upgrades, or dam and recreation area opening times, please call the WaterNSW Helpdesk on 1300 662 077 or visit the dam pages.
