Tasman Tank Co helps keep water flowing across the ditch
A recent local water supply project in South East Queensland highlights the ease of construction and cost effectiveness of the innovative bolted steel storage tanks from the Tasman Tank Company.
The $A2.2 million project, which was delivered by Allconnex Water’s Logan Water Alliance, involved the construction of a new 1.2 megalitre potable water storage tank (reservoir) and 4.2 kilometres of associated water pipelines (2.9 kilometres of rising main to the reservoir and 1.3 kilometres of gravity main from it) in the fast growing Cedar Vale region.
The new infrastructure will provide more reliable water services to the residents of Cedar Vale and its surrounds, as well as supplying the area with water for fire fighting purposes.
John Green, senior project manager with Logan Water Alliance, explains that the Cedar Vale project was a fairly straightforward job.
“There were three small poly tanks previously on the site. It was just a matter of pulling them out and upgrading the foundations for the larger tank.
“The ground conditions were not ideal so significant modifications had to be made to the ground before the new tank could be built onsite.
“But once that was done, the erection process was very quick and straightforward.
“The tank, which is a liner-free storage tank, is now full of water and the finished quality is very good. And being coloured green, it blends in well with the environment,” Mr Green says.
David Baker, major project sales manager with the Tasman Tank Company, explains that the storage tank chosen was the LIQ Fusion 7000 FBE bonded steel tank that is fully sealed between the panels, and does not require a liner.
“This type of tank has been on the Australian market for over three years now and has proved itself to be the most cost effective storage solution compared to concrete and welded steel tanks, and is very popular for municipality water applications.
“The factory applied coating complies with AWWAD103 and has NSF-61 international Standard approval.
“It is our proprietary coating that we get from our US suppliers, the internationally respected Tank Connection group and Akzo Nobel, the world’s largest powder coat supplier.
“Tank Connection technology delivers the best bolted water containment systems available anywhere, with optimum performance for potable water, industrial liquids, waste water, effluent, raw water, demineralised water, process water and anaerobic digesters,” Mr Baker says.
“It is unmatched compared with all other bolted and welded tank linings.”
He went on to explain that the ease and speed of construction is another major plus for the bolted tanks.
“One reason the modular systems are so popular is because access to a building site is often difficult.
“For example, with a welded tank you need to bring in large cylindrical sections and weld them onsite, whereas all our panels are flat packed into easily managed 1.2m2 flat packs.
“The panels are simply bolted together with no need to build scaffolding. Everything is hydraulically jacked from the floor up as we build the tank, with the tank, including the tank’s roof, built at ground level.
“The tank is hydraulically jacked as you go. Meaning there is no working at heights. You just keep bolting the panels in place as you go,” Mr Baker says.
“The other big advantage over other types of storage tanks is the ease of increasing capacity if needed in the future. We can achieve this by simply installing the hydraulic jacks again and adding more panels.
“Plus bolted site construction allows for control of all quality processes in good or bad weather. It is not subject to uncontrolled factors from outside influences, which in the case of non-steel tanks can impact upon mixtures specifications and joint connections.”
Mr Baker advises other municipalities, councils and companies contemplating similar projects requiring large storage tanks to take a close look at Tasman Tank’s modular storage tanks.
“They are quick to construct, and expedite the time and money on projects. Plus they can be successfully blended in with a building or landscape, turning the tank into a feature rather than an eyesore.”
Mr Baker said bolted tanks have steadily overtaken alternatives because they don’t leak, they are less expensive to build in the first place, they are cheaper and easier to maintain and typically outlast alternative materials anyway.
