A forward-thinking local government organisation in New Zealand has chosen to install bolted steel tanks from The Tasman Tank Co. instead of the traditional concrete tank for potable water storage.
Westland District Council, based in the remote and climatically challenging West Coast of New Zealand’s South Island is reaping the benefits of breaking with tradition and adopting the latest Australasian manufactured technology in storage tanks for potable water supply.
Tasman Tank installed the cost-effective bolted steel storage tank for the Council to supply potable water to urban and rural consumers in the area.
Following the success of the first installation, the council has continued to invest in Tasman Tank's bolted steel storage tanks for its potable water supply in the region, with the latest tanks selected through public tender to be installed in the coming months.
Modular tanks from Tasman Tank are speedy and safe to erect in diverse environments. Bolted tanks can be readily and aesthetically blended with surrounding buildings in applications such as commercial and industrial mining, energy, resources, manufacturing, government and infrastructure, engineering, food and beverage processing, chemical and primary product processing, water and wastewater treatment as well as fire protection.
Ian McGregor, Tasman Tank's New Zealand Territory Manager says the Council has now invested in two 450m³ bolted steel storage tanks for its Hokitika tank farm, with the latest 1,500m³ in production to be installed in the coming months.
He says that the benefits delivered by bolted steel tanks have been a major factor in the Council’s decision to move away from concrete tanks.
Listing out the advantages, he says bolted steel tanks do not leak, are less expensive to build, are cheaper as well as easier to maintain and typically outlast alternative materials such as concrete.
Mr McGregor explained that while welded tanks are an option, the cost factor is a deterrent.
In addition to large capacity industrial tanks employed by the Westland District Council at their tank farm, Tasman Tank is also constructing a large 2100m³ storage tank on the Hokitika dairy site for potable water storage to service the dairy factory as part of a joint venture with the Council and the Westland Dairy factory.
Tasman has also recently supplied two 500m³ potable water tanks for the townships of Franz Joseph and Fox Glaciers, which all form part of the Westland District Council area.
All the water storage tanks are steel bolted round tanks built with hot dipped galvanised sheet panels that have been powder-coated for additional durability. Mr McGregor says that all tanks have a design life exceeding 50 years with a maintenance schedule.
The Council is very happy with the innovative tanks and the service provided by Tasman Tank.
Commenting on the contract won by Tasman Tank for a 450m³ water reservoir for the township of Hokitika about 10 years ago, Westland District Council’s Manager Professional Services Business Unit, Mr Peter Anderson says low price was not the only reason for accepting Tasman’s tender.
Simplicity of design, speed of construction, aesthetic advantages and ability to erect the reservoir in confined areas were all factors that contributed to Tasman Tank winning the contract.
Mr Anderson adds that the contract was completed within budget and time. Based on Tasman’s performance, the original contract was extended to include an additional 450m³ reservoir, which too was completed as per budget and time specifications.
Mr McGregor says that Tasman has been successful with tenders for reasons such as price, experience and customer service.
Another major factor for the fast adoption of bolted tank construction throughout Australasia is suitability and speed of construction in remote and climatically challenging areas.
He says that factory coated, site-bolted steel tanks offer superior quality control during the manufacturing process. They are less subject to uncontrollable factors such as inclement weather, which in the case of concrete can impact upon mixtures specifications and joint connections.
Tasman Tank is a leading name in the tank building industry offering in-house design, manufacturing and installation expertise. All Tasman tanks are certified to relevant codes with independent engineers providing verification of specifications and performance.
Bolted steel tanks from Tasman Tank are available in capacities ranging from kilolitres (KL) to 30 megalitres (ML).
