System: 33,000 Potable water plant

Client: SANTOS

Location: Wallumbilla, QLD



As part of the LNG project, SANTOS needed a reliable and effective method of providing clean potable water to camps. One of the main challenges on Wallumbilla is the water consists high level of salt and needs to be treated to meet Australian drinking standard.



To ensure a constant and clean supply of water to Wallumbilla camp, Tricomms Construction designed and installed a potable water desalination system capable in treating brine water to drinking standard.


The solution components included:


Potable water desalination plant

  • This potable water plant is capable of treating up to 72000L/d of bore water to a potable use.
  • The treatment includes a primary two multi-media filtration followed by two cartridge filtration running in parallel to remove larger particles
  • Two sets of reverse osmosis filtration systems are installed to remove salt from water
  • pH correction system is installed to ensure a healthy pH range for human consumption
  • Water chlorination is provided to kill certain bacteria and other microbes
  • Treated water’s pH, free chlorine, temperature and conductivity are analysed and recirculates into the treated water tank to ensure the water is readily for use in SANTOS camp

Remote monitoring has been fitted to enable ongoing system assessment by qualified Tricomms Construction’s technicians. It’s like having your own technician onsite.



  • Up to 72,000L/d of filtered/disinfected water available for camp use
  • Environmental compliance
  • Remove salt from water to achieve Australian drinking water standard
  • Optimised site water management and efficiency
