Lenthalls Dam Upgrade, Queensland
As the main water supply for Hervey Bay in Queensland, Lenthalls Dam received an upgrade which included the increase of its storage capacity and an improvement in water flow through the installation of an ingenious radial ‘Flow Gates System’. The demand for this project stemmed from a requirement to supply a reliable and sustainable water resource for local communities, and to promote the economic growth and development of the Hervey Bay area.
Our role
Geotech was awarded the principal contractor role to increase the storage capacity of Lenthalls Dam through modification of the 70m wide ogee spillway and 300m long embankment.
The scope of works included the fabrication, supply and installation of the South African-designed ‘Flow Gates System’, embankment earthwork, Gabion mattress protection and fabrication, and the installation of permanent GEGA 3750kN anchors.
