Tyabb Reservoir Earthworks, Lining and Floating Cover

Project Overview

Managed by Melbourne Water, Tyabb Reservoir is a critical storage point used to meet summer water supply demands for the Mornington Peninsula.

The project included the construction of a dividing embankment inside the reservoir to create two independently operating basins. Each basin was then lined, and floating covers were installed to protect the quality of the drinking water that is received from Melbourne Water’s Cardinia Reservoir and Tarago treatment plant.

Ertech worked with the JHKBR JV to deliver the project on time and to the satisfaction of client and community stakeholders.
