Project Overview / Description

Townsville City Council is upgrading the Paluma Dam Spillway in Paluma. The project was awarded to CivilPlus Constructions who started work on 08/09/2021.

The project objective is to construct a reinforced concrete spillway with anchors into the rock foundation. 

The existing dam spillway is a natural rock formation of granite. The granite is weathered and starting to decompose, which could adversely affect supporting structures like the spillway bridge and dam ogee weir. Townsville City Council is upgrading the spillway to prevent its deterioration. 

Project Features:

    • Delicate and precise rock work adjacent to existing spillway bridge and Ogee weir
    • Concrete cutting and coring
    • 300 tonne of rock demolition and removal predominately using handheld tools
    • 140 m3 of blinding concrete to prepare the foundation for anchoring
    • 160 of 3.0 m long grout rock anchors including drill and grouting
    • 110 m3 of reinforced concrete to form the new spillway
    • 61 m of sub surface drainage
    • 30 m3 of rock scour protection
    • Environmentally sensitive area being World Heritage Wet Tropics
    • Remote location with dirt road access and no mobile coverage
    • High rainfall region
