Waterworks Reserve Upper Reservoir Dam Upgrade

What's this project all about?

TasWater undertook essential infrastructure upgrades to Upper Reservoir Dam at Waterworks Reserve from February 2021 to November 2021.

The Upper Reservoir Dam is over 150 years old and is a valuable aspect of Waterworks Reserve and critical to Hobart’s water supply. Central to the works are upgrades and improvements to the dam. These upgrades will help to ensure the continued security of our water supply.

Works involved with the upgrade included:

• Modifications to the embankment to enhance its future safe performance including raising the dam wall, raising the earth at the crest of the dam for safer access, modifying drainage, revegetation and upgrading the fencing
• Improvements to the dam infrastructure include stormwater management upgrades, outlet works refurbishment and installation of performance monitoring facilities
• Upgrades to Depot Road.

To complete the upgrade safely, the water level in the Upper Reservoir Dam was drawn down temporarily.
