Water Tanks

General

What size tank do I need?

When considering what size to purchase, there are numerous factors worth considering. What do you want to use the water for? Is it just for drinking water or to irrigate your garden? What is your existing household water usage? Is there a past water bill you can refer to? How many people (and animals) will be using the water? Is the tank for storing bore water or collecting rain water? How much room do you have for a tank?

Phone or email us with as much information as possible and we will happily assist you to work out the best product for your needs.

What fittings are included with the tanks?

All tanks come standard with an inlet, an outlet, a lid and an overflow. See our Water Tank Order Form page for placement diagrams and more information.

What colours can I choose from?

A full range of Colorbond® colours.

Do you sell your tanks at other locations?

Yes we have agents that sell our tanks across the NT and northern WA.

Water Collection & Usage

Can I use it for rainwater? Bore water?

You can use our tanks for rain water, bore water or both!

How can I work out how much water I use?

If you live in an urban area your water bill is the best guide. Otherwise there are various websites that can assist with estimated usage. 

How much rainwater can I collect from my roof?

There are various websites (tools) that can assist with this question.

An area of roof space of 1m x 1m will collect 1L of water after 1ml of rain.

Can I drink the water?

There are numerous debates about this. We drink our tank water!

The NT Government website states that ‘Rainwater is considered a high-quality water source with lower contamination risk than surface water.’ It further states, however, that this is not guaranteed and offers suggestions on maintenance and how to keep water safe and drinkable.

Quality

Why is plastic a good material for water tanks?
  • It is light-weight and easily transportable
  • It won’t rust
  • It protects your water from sunlight, which can cause algae in wate
  • You can seal it tight so no foreign objects or predators can enter the tank
  • It is durable, having a long life span compared to other products.
How long do your tanks last?

A tank should last at least 10 – 20 years. All our tanks come with a 10 year fix or replace warranty.
