Rainwater Tanks Frequently Asked Questions

Here are our answers to some commonly-asked questions about Rainwater Tanks.

  • How much rainwater can my home harvest?
  • The amount of water collected by your rainwater tank will depend on a number of factors, such as the size of the roof, the amount of rainfall expected and the number of downpipes leading into the tank. It is estimated that every millimetre of rain on 1m2 of your roof will collect 1L of water. Therefore, a light 10mm of rain each day over four days falling on a 100m2 roof connected to a rainwater tank can collect around 4000 litres of water.
  • Is rainwater safe to drink?
  • Water supplied through public water mains is often treated with chemicals and can collect additives through the storage, transport or cleaning process. Rainwater is fresher, cleaner and has a better taste.
  • Do I need a slimline or round rainwater tank?
  • Your choice of rainwater tank will depend on your water requirements and the amount of space you have available. Slimline tanks are more suited to those with smaller water demands and space restrictions. Round rainwater tanks use more space, but are more economical in terms of dollars per litre.
  • Are there rebates available to assist in purchasing a rainwater tank?
  • There are Federal Government rebates available to customers who install rainwater tanks, as well as State Government rebates in many regions.
  • Do water restrictions still apply if I am using a rainwater tank?
  • By harvesting the rainwater falling on the roof, rainwater tank owners in Australia can avoid water restrictions, allowing them to keep a clean car, a full swimming pool and a healthy garden.
  • Do rainwater tanks provide benefits for the environment?
  • By installing a self-sustaining water supply, you can reduce your reliance on the public water system, minimising the pressure to develop new, environmentally-damaging water sources. Storm water run-off is also reduced, preventing damage to delicate local rivers and lakes.
