Our Water StorageTanks

Every Aqua Tank water storage tank is manufactured to the Australian and New Zealand design standard (AS/NZS 4766:2006) and produced from virgin food grade material to AS/NZS 2050:2006. Our storage tanks are moulded in one piece and are designed to ensure that unnecessary stresses are adequately contained within the unique ribbed side walls of the tank. The ribs help to contain the 'hoop' stresses exerted on storage tanks. Additional strength is moulded into the tank through the combination of a moulded and ribbed dome which also houses the manhole riser(s). Aqua Tanks build structural strength into our watertanks during the design and moulding stages. This means we do not have to add additional structures or frames inside the tanks after moulding.

Water Storage Tank Features

• Polyethylene minimises occurrence of algae growth within water tanks.
• Colour range available to blend in with the immediate environment.
• UV Stabilized material water storage tanks.
• Excellent impact resistance for storage tanks
• Water tanks come complete with female threaded inlet
• Large storage tanks have inlet and overflow positions moulded into the manhole riser
• Maintenance free, made to last.
• Applications for our water storage tanks include drinking water, fire protection, irrigation, disaster preparedness, and rainwater collection.
• Design complies with applicable New Zealand and Australian standards for storage tanks, and U.S. FDA regulations storage of potable water.

Polyethylene

The polyethylene product used to make Aqua Tanks and Aqua Filters is an extremely tough and durable lightweight thermoplastic material. The colour and ultra-violet stabilizers are compounded to give long-term resistance and stability to harsh sun. No chemical reactions take place during the manufacturing process and consequently there is no tainting of water with polyethylene. All of our tanks are manufactured using virgin linear low density polyethylene (LLDPE) which complies with AS/NZS2050, the standard for food grade material. The material is recyclable and can be repaired by a heat welding process if damaged.

Plastic, or polyethylene, water tanks are now the biggest selling sector of the water tank market and has been developed and tested in the market place over many years for the manufacture of water storage containers. It cannot rot or corrode, and is UVstabilised for New Zealand conditions. It is also resistant to algae growth as a result of its formulation and not from any addition of fungicides.

Aqua Tanks are produced using a rotational moulding process so that there are no joins. 

Water stored in polyethylene has no taste from the tank material because nothing leaches from polyethylene. Any ‘taste’ in the water will be the result of the maintenance of your roof, spouting, downpipes, gutters and the tank itself. You should be aware though that most rainwater tanks are not approved for drinking water by the local authorities in urban areas unless approved cleaning and sterilisation processes have been used to treat the water. This policy is not based on any "fears" about any of the materials used to manufacture tanks and relates back to the possibility of unclean drinking water from poorly maintained roofs.
