Kununurra Diversion Dam Regulating Structures

From 2009 – 2014, McElligotts completed gradual remediation works on the Kununurra Diversion Dam regulating structures as part of a five-year contract for the WA Water Corporation. The Kununurra Dam consists of 20 gates, requiring us to complete works on at least four per year. The remediation process included abrasive blasting, scaffolding, and protective coating application on the internal and external structures.

Our team had to setup specialised equipment on barges and engineer specially-designed scaffolding for the unique conditions presented in this project. Each gate took about three months to finish, owing to the accessibility and sheer scale of each radial gate. We carefully assessed the surroundings and identified suitable primers and protective coatings that will last for many years to come.
