Paradigm Flow Services Ltd (PFS) has successfully applied their game changing digital dry deluge testing system, Dry-Flo® on a non-oilfield project on a major transport tunnel construction project in Sydney, Australia. The scope of work allowed the customer to accurately quantify and verify deluge system performance, achieved without the use of a single drop of water during the high activity commissioning phase of work.
PFS worked closely with EFTECH International Pty, an Australian mechanical, electrical and instrumentation contractor in an integrated partnership, testing 678 deluge zones incorporating over 10,000 individual Sprinkler nozzles in less than 3 months.
Dry-Flo® is a smart digital deluge testing system that enabled water free system testing of the New M5 (18.6 km of highway) section of the New M5 WestConnex project; a 33 Kilometre motorway scheme in Sydney. The scheme is a joint project between New South Wales and Australian Government to widen and extend improve the motorway infrastructure in and around Sydney.
Andrew Manning, EFTECH International Managing Director believes
Dry-Flo® is revolutionary for tunnelling and the broader infrastructure industry, “The technology commissions a deluge system, sometimes kilometres of sprinklers at a time, without using a single drop of water. This is a major development, with projects gaining from significant downtime reductions, cost benefits and enhanced productivity. The advantages are far superior to any other approach, while the fact it also minimises the environmental impact through using less water makes it commercially very compelling,” said Mr Manning.
Hayley Young, Sustainability Manager at WestConnex comments, “Using Dry-Flo® testing for tunnel construction results in a new way of approaching deluge testing in a more sustainable manner. DryFlo® reduces the size of exclusion zones, removes the requirement for water management, or the need for the fire water feed system to be operational. This significantly improves production. Given the improvement in simultaneous tunnel production, Dry-Flo® testing has a relatively short payback period.

project.
She confirms, “This trial found that Dry-Flo® outperformed wet testing, and progressed tunnel schedule as most of the system could be proven (as well as any issues rectified) before the deluge lines in the tunnel were energised with water. Whilst the specialised labour and technical equipment required to implement Dry Flo® testing were higher than traditional wet testing, the savings in water use and the additional productivity achieved was of substantial benefit to the Project as a whole.”
Hugh Mackenzie, PFS MD explains, “The value proposition of our Dry-Flo® system to the customer is very significant, especially when you consider the benefits of keeping the tunnel dry during commissioning to allow other activities to progress whilst saving millions of litres of water and energy opposed to what would have been required if conventional wet testing had been carried out.
The data acquisition software which accurately simulates wet flow testing in virtual litres, detected various types of debris in many systems with such accuracy that we were able to immediately rectify issues on the fly, saving the end client valuable time and effort.”
He continues, “We have yet again demonstrated on this World-first project that the use of Dry-Flo® saves time, money, and water with less carbon impact than conventional wet testing. During this commissioning operation the system was deployed as a temporary service, however Dry-Flo® can also be permanently installed to allow unmanned remote periodic testing to take place without any disruption to the fire protection system or the area it has been installed to protect.”
