SAGE's partnered approach to servicing niche gas utilities


Comdain is a leading construction and maintenance service specialising in gas, irrigation and water. They’re the primary operational and service provider for Victorian gas distributor Multinet Gas (MG), who distributes natural gas to 660,000 residential, commercial and industrial customers. Comdain service MG’s south-eastern distribution network.



Comdain must maintain MG’s 164kms of transmission pressure pipelines and 9,866kms of distribution mains without disturbing customer supply.

To do this, the company require specialised skills that can be applied in a natural gas infrastructure environment.

Other service challenges include location access, working in confined spaces, working at heights, and traffic control. 



SAGE Automation worked with Comdain to develop a custom Service Level Agreement (SLA) suited to the industry and Comdian’s needs.

Under the SLA, SAGE handles all electrical and telemetry work for service, maintenance, and projects such as upgrades, or new site installations.

It appointed a full time technician trained in gas field operations for ongoing works. Finally, SAGE applied its systems and process knowledge built from years of experience, to improve equipment reliability.


Key Outcomes

  • SAGE and Comdain’s service has improved reliability of MG’s field assets through regular maintenance and best practice processes. A regular maintenance program for any utility will improve asset lifespan and reduce costs associated with breakdowns.
  • The ongoing partnership between Comdain and SAGE Automation allows each partner to perform their own specialties to keep systems running. Comdain focuses on construction and maintenance services while SAGE does the electrical and telemetry work.
