Oura Water Treatment Plant - Stage 2, Reservoir & Aerator Construction

Overview

Goldenfields Water have engaged Quay Civil Pty Ltd to undertake the $12.6 million detailed design and construction of new water infrastructure at the Oura Water Treatment Plant.

The design and construction of the reservoirs and aerators forms Stage 2 of the Oura Water Treatment Plant Upgrade.

Works for Stage 2 will include:

  • the finalisation of the preliminary designs for the construction of the proposed multi tray aeration unit and structural tower
  • transfer pipeline
  • two reservoirs (4ML each)
  • associated civil and electrical infrastructure along with instrumentation for the operation and monitoring of the system

Timing

  • Site mobilisation was completed mid-September 2023.
  • The base of the two reservoirs were poured in January/February 2024.
  • The DN750 stainless steel inlet and outlet pipes that the GWCC Mechanical team fabricated specifically for the project have been installed.
  • A total of 48 individual concrete panels make up the walls of the reservoirs. Each panel was poured individually then lifted into place via a crane over several months, before a specialised type of concrete was poured between each panel to connect them. This process was completed in May 2024.
  • Hydrostatic testing of the tanks was completed successfully in March 2025.
  • Aeration units were assembled and lifted onto their supporting structural tower in March 2025. Connecting pipework is to be installed and hydrostatically tested in April 2025.
  • Final civil and earthworks are to be completed in April 2025, including surface water drainage and road construction.
  • Roofing for the tanks is to be installed in May 2025, marking the full completion of the project and stage 2 of the Oura Water Treatment Plant Upgrade.

Project Benefits

  • Increased water storage capacity for growth in towns supplied from our Oura Scheme
  • Reduced potential for disruption to supply when maintenance works are carried out on reservoirs
  • Increased treatment time to improve water quality
