Reflex circular formwork used at Burringbar WWTP is a popular solution for Waste Water Treatment Plants
RMD Australia has designed and supplied a formwork and shoring solution for the construction of five circular wall tanks at the Burringbar Waste Water Treatment Facility in Mooball, New South Wales.
Part of a sewerage scheme, the new facility will help to replace septic tanks that are currently in use in the Mooball area. Many of the existing septic tanks perform inadequately; therefore replacing them with a fully functioning sewerage system will not only improve odours, but also the environmental quality of aquifers and surface waters, reducing potential health risks.
The five tanks comprised; an overflow storage tank, two reactor tanks, a balance tank and a site pump station. RMD Australia was tasked with providing a solution to cater for each application.
RMD Australia ensured that the best solution was provided for the various tanks
Working alongside the main contractor Quickform Constructions Pty Ltd, RMD Australia supplied a solution for the first two tanks consisting of a shuttering system constructed from Superslim Soldiers, RHS beams and vertical LVL, with two layers of 6mm plywood on the face.
RMD Australia also supplied its heavy-duty Strongshor shoring system, which was used with the client’s plywood and LVL to construct the concrete roof of the pump station. RMD also supplied equipment for larger 4.8m high forms for the construction of the balance tank.
Reflex panels were used on the Reactor Tanks
The two reactor tanks, which have a diameter of 7.45 metres and a height of 2.2 metres, were poured using RMD Reflex panels. The preassembled galvanised circular wall formwork system is capable of withstanding up to 60kN/m2 and provided the perfect solution as it could be accurately adjusted to meet the exacting standards required for each tank.
The largest part of the project, the overflow storage tank, was completed last and required extra panels to be sent to site to meet it’s 4.5m wall height. The solution for constructing this higher tank was to use two 2.4m Reflex panels connected on top of each other.
“Coupled with its excellent on-site support, RMD Australia was able to demonstrate flexibility and innonvation…”
Chris Bien of Quickform Constructions Pty Ltd, Burringbar Waste Water Treatment Facility in Mooball, New South Wales commented; “In working with RMD Australia on the Burringbar Water Treatment Facility, we have been able to utilize its expertise in providing bespoke formwork and shoring solutions to cater for the exact needs of the project. “Coupled with its excellent on-site support, RMD Australia was able to demonstrate flexibility and innovation to ensure a successful conclusion.”
Frank Sulentic, RMD Gold Coast Branch Manager commented; “Playing a key role in what is a landmark development for the Mooball community is hugely satisfying, allowing us to showcase both our design expertise and logistical capabilities.
“Throughout the project we have worked closely with Quickform Construction to overcome changes to the overall design of the facility, and ultimately deliver a cost effective and efficient formwork solution.”
