Water Storage Brisbane

When you consider water storage, you need to consider what purpose it will be useful for.


Water Storage is useful for:

  • Irrigation
  • Water for the house (laundry & toilets)
  • A backup water source in case of a fire 
  • Spare water for pot plants or hand watering

How much water storage do I need?

Water tanks hold a set amount of water, and therefore can only be filled up once during a rain event unless the water is being used or transferred to another tank. Generally, we don’t irrigate when it’s raining, so the question is asked how much do I need?


To answer this question, we consider questions like the size of your landscape, how much water does your roof capture and how quickly will you use the stored water. Using this information we can start to map out how much water is getting used over a period of time, to help provide you with the best water storage solution for your circumstances.

 Case Study Example: (These figures are not based on any real-life scenarios) 



Steve lives in a town where the water pressure isn’t great, so Steve installed a tank and a pump to improve the flow and pressure that he currently receives from the local council. Steve decided to install a top-up into his tank which will keep his tank filled to a preset level.



Steve has a 10 000L tank, which gets filled up each time it rains (this can vary). Steve irrigates his lawn 3 times per week and uses 1000L of water per week. 



Considering that every tank has a certain amount of water that doesn’t get used (the bottom 10% or 1000L) we will say that Steve has 9 weeks worth of water.



Every time it rains Steve has the potential to store 9000L which is equivalent to about $18. 

A 10000L tank with a basic pump cost approximately $3500. Steves tank needs to be completely filled 195 times before he starts saving money (this is without the cost of pump services and power usage).



For Steve, having a tank is a good option because the purpose of the tank is not to save water but to hold water that allows his irrigation system to work. If Steve was trying to save money then the option of installing a tank may not be the best idea. If Steve wanted to wear the cost and attribute the loss to helping the environment then no one can put a price on that except Steve.



Water tanks are a fantastic option if they solve a functional issue such as low pressure or low flow. If water tanks are your only water source then your mindset shifts because you want to capture as much water as you can because that means you won’t have to buy water to have a shower.
