Roadtrain® Delivers Safe Environmental Discharge for Saibai STP
September 29, 2022
Located just 4km from Papua New Guinea (PNG), Saibai Island is the Northern most Island of the Torres Straits, with approximately 500 residents. A new sewage treatment plant was recently commissioned to deliver high-quality water for environmental discharge into the Arafura Sea.
Hydroflux Epco’s well proven Roadtrain® RBC Decentralised Solution was selected for the Island due to its excellent track record in similar installations providing high-quality discharge. The process has been specifically designed to suit remote installations and standardized across The Straits in six locations.
“The Hydroflux range of decentralized solutions are tailored to suit sites such as Saibai. We prioritise delivering infrastructure that is suited specifically to resorts, villages, remote communities and mining camps. Our range of Roadtrain® transportable sewage solutions include the ORIGINAL, PLUS, ADVANCED and ULTRA. The process selection for each site is targeted to suit the application, the location, and the capabilities of the operational staff on the ground.
I have just returned from a new multi-million dollar project we are starting in Vanua Levu Fiji, using our Roadtrain® ADVANCED technology. The exciting aspect of that project is that we can convert the Roadtrain® from the ADVANCED to PLUS design, in stages, over a period to suit growth. This allows the client to double capacity within the same footprint with some minor additions in the future” says Paul Cobbin, General of Decentralised Solutions for Hydroflux Epco

Globally there are over 150 Roadtrain® systems that have been used for a variety of decentralized applications. Installations from the late 1960’s in South Australia, Victoria, New South Wales, Queensland, Papua New Guinea and the Middle East are still in operation, demonstrating the robustness of design and life cycle benefit of using engineered tanks as opposed to modified containers.
