System: 72,000 Potable water plant

Client: SANTOS

Location: Wagoon Umo, 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 Wagoon Umo camp, Tricomms Construction designed and installed a potable water system capable in treating bore water to 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 two primary 30” DMI filtration followed by 2 micron filtration at 20 and 5 micron in parallel
  • 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 turbidity are analysed and recirculates into two of the treated water tank as well as a water discharge line to ensure the water is readily for use in SANTOS camp
  • 3 potable water tanks capable of holding up to 300,000L of water. A truck load out point is installed to transport water to other camps.

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
  • Optimised site water management and efficiency
