Scope

Two operators were mobilised to Ingham, North Queensland, to complete smoke testing on sections of the sewer network. Non-toxic smoke was introduced into the sewer lines to identify potential leaks, defects, illegal connections, and inflow or infiltration points. Any smoke release observed during testing was recorded for further investigation or rectification, assisting in assessing the condition and performance of the sewer network.

Scope of Work:

  • Mobilise two operators to Ingham, North Queensland, to undertake smoke testing on selected sewer lines.
  • Introduce non-toxic smoke into the sewer network to identify potential leaks, defects, illegal connections, and inflow or infiltration points.
  • Inspect surrounding areas for smoke release and record any defects or issues identified during testing.
  • Provide findings to assist with further investigation, maintenance, and repair planning.

Challenges

  • Skill Acquisition & Mentorship: Executing smoke testing protocols for the local crew for the first time required rapid, on-the-job upskilling. Coordinating the logistics of integrating an international subject matter expert to train the local team in a remote setting added an initial layer of complexity.
  • Data Capture & Systems Adoption: Accurately logging tested assets and distinguishing between normal network venting and actual infrastructure defects required the crew to rapidly adopt a new digital workflow while operating in the field.
  • Remote Logistics & Wellbeing: Operating in Ingham required strict equipment management without immediate access to regional depots. Furthermore, the combination of learning new technical skills, navigating the North Queensland climate, and managing the fatigue of living away from home added cognitive and physical strain to the crew.

The outcome

The project was delivered safely, efficiently, and with minimal public disruption, providing the Council with critical, highly accurate data regarding their sewer infrastructure. By leveraging international expertise from New Zealand to upskill our local operators and successfully rolling out Utility Track for precise defect logging, we delivered a comprehensive asset assessment. This effort not only equipped the client with the actionable insights needed for targeted maintenance but also established a fully trained crew and a proven operational template for future remote testing deployments.
