The largest concrete water tank ever to be constructed in regional Western Australia has been completed to improve water quality and secure supply from Merredin to Kalgoorlie, north-east of Perth.
More than 2000 cubic metres of concrete was used in construction of the 42 million-litre water storage tank. Onsite concrete production and innovative methods were employed to enable the tank floor and roof to be constructed of concrete in a single pour, according to WA Minister for Water Dave Kelly.
The $30.1 million project included converting the existing reservoir to an overflow area for the new tank, a new chemical dosing facility, extension of the access road, construction of pipework connecting the new tank and fencing.
A 32 million-litre water storage tank is close to completion in Dedari for the Shire of Coolgardie and Kalgoorlie-Boulder while a 20 million-litre tank constructed in Karratha was completed in July.
The contractor appointed by the WA Government to design and construct all three tanks was SRG Global. The engineering and construction group has a civil team that specialises in constructing bridges, windfarm foundations, water tanks, cryogenic tanks, silos, and dam strengthening.
Construction of the three water tanks form part of a $628.5 million investment in regional water infrastructure projects in the state over the next four years.
