GAYNDAH AND MUNDUBBERA RAW WATER INTAKES

PROJECT DESCRIPTION:

As part of the Australian and Queensland Governments Natural Disaster Relief and Recovery Program, Abergeldie completed construction of the new raw water intakes from the Burnette River at Gayndah and Mundubbera after they were destroyed in the 2011 and 2013 floods.

The pump well intake structure at Gayndah was constructed in 5m of water beside the existing Claude Wharton Weir and the well shaft was built by stacking eight precast segments on top of each other. Each segment weighed between 34 and 50 tonne.

The intake structure at Mundubberra involved the replacement of the existing jetty to suspend the water intake pumps and pipework. The jetty consists of 900mm x 10m long steel lined reinforced concrete piles socketed 3m into bedrock.
