Sector: Resources and Remote site

System: 33,000L/d Potable water plant

Client: SANTOS

Location: Unburri, 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 site was the limited access to water and it was important to use water wherever possible.



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


The solution components included:


Potable water 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 30” DMI filtration followed by two micron filtration at 20 and 5 micron
  • pH correction system is installed to ensure a healthy pH range for human consumption
  • Water chlorination provides sterilisation to kill certain bacteria and other microbes
  • Treated water’s pH, free chlorine, temperature and turbidity are analysed and recirculates into the treated water tank to ensure the water is readily for use in SANTOS camp

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



  • Capable of treating up to 72,000L/d of filtered/disinfected water available for camp use
  • Environmental compliance
  • Optimised site water management and efficiency
