Not knowing the difference between Aquaplate (steel) and Poly Tanks!

Aquaplate tanks:

 Inner coating of Aquaplate is designed to prevent corrosion.

 Can be made to size (custom) and come in a range of sizes.

 Are a little dearer than Poly tanks BUT have a much greater lifespan and better quality of drinking water.

 Are cooler than other tanks, so are extra safe for the storage of drinking water, plus have less bacteria growth than in plastic tanks.

 Aquaplate tanks do not bulge or flex when full or exposed to heat, so should survive fire or flood damage.

 Easier to be recycled at the end of their lives. They can be made into garden beds, dog kennels, or taken to landfills as a relatively benign material.

 Come with 20 years steel warranty.

 Better for health and wellbeing.

 Are approved for use as bushfire protection tanks, and recommended for use in rural, fire-risk areas, as they are non-combustible materials.


Poly Tanks:

 Poly tanks will degrade and weaken over time with sun exposure, despite having UV inhibitors added.

 Can only be made to the size of the ‘tools’- usually around 2.1 high.

 Are usually the cheapest tanks available, but with only half the lifespan of an Aquaplate tank(depending on the amount of resin).

 Considered best to use for grey water, but not for drinking water as they heat up and encourage bacteria build-up.

 Will break down and split from heat and cold exposure over time causing expansion and contraction of material.

 Poly tanks will degrade to a point where they are not repairable. You will need to find a company with a recycling system (of which NTM is one).

 10 year material warranty.

 Bacteria build up is greater due to greater heat build up inside. The hotter the water, the more bacteria.

 Are not approved for bushfire protection tanks and are not recommended for rural areas subject to fire risk, as they are combustible and will not withstand a fire.
