Treatment Infrastructure

Augmenting existing natural water courses and topographical features, a series of flow regulators, sills and a 1000ML / day pump station were constructed to facilitate environmental flow management.

Works Undertaken

  • Construction of seven 750mm pump columns forming one of the largest water pump stations in Australia.
  • Construction of 2100mm RCP
  • Construction of 900mm PE branch pipeline
  • Construction of four new regulating structures and refurbishment of another including the installation of some of the largest penstock gates in Australia
  • Construction of stop banks and levees
  • Flood protection works to avoid delay to construction program
  • HV power supply to new pump station (additional scope)

Highlights & Innovations

  • Early mobilisation was required to commence additional earthworks to protect the work site due to unseasonal heavy rainfalls that could have potentially flooded the work zone. This was identified using modelling technology and Comdain was able to determine the peak river level and ascertain the levee protection works required. Protection was achieved and the project commenced on schedule.
  • Industry recognition was received through the award of the prestigious CCF Earth Award and Banksia Award (Water) in 2013.
  • Positive Indigenous & cultural heritage engagement and outcomes.

 

“The civil and engineering works were of excellent standard; however it was the overall management of the project that stood out the most. This, I believe, has led to the Hattah Lakes construction project being the most successful project under the MDBA Environmental Works and Measures Program.”
