The Benefits of Rain Water Tanks

Australia is officially in the “worst drought in on record, with BOM climatologist David Jones saying the drought has now exceeded the Federation Drought, the WWII drought and the Millennium drought in terms of its severity through the Murray Darling Basin” (

Now more than ever is the perfect time to install a rain water tank on your property.  The most common water source in Australia is mains water with 93% using it as their primary source in March 2013. Water shortage will continue to be a problem for many years to come, because of irregular weather patterns resulting in decreased rainfalls across Australia as well as growing population, especially in urban areas. Now is the time for people to start to adapt to the changing environmental climate that is rapidly occuring. Sydney is currently on Level 2 restrictions which includes (source;

  • You can only water your garden before 10am or after 4pm with a watering can or bucket. Hoses are not permitted at any time.
  • ‘Smart’ watering systems that include automated weather adjustment, a rain sensor or a soil moisture sensor and drip irrigation systems may only be used for 15 minutes per watering zone before 10am or after 4pm
  • The use of unattended hoses is not permitted
  • Hosing of hard surfaces is not permitted, unless in an emergency or for health and safety reasons
  • You can wash your car with a bucket or at a commercial car wash
  • You will need a permit before filling a pool over 500L. You can only top up an existing pool or spa, using a hose fitted with a trigger nozzle, watering can or bucket for a maximum of 15 minutes a day.

Over half of Australians still use mains waters as their  water source for their gardening. Rain water is not for use with cooking or for drinking water, it is the best source of water to use for your household gardening needs. The main benefits of using rain water tanks include;

  1. Decreased usage of your water mains – you can use your rain water collected for garden use, filling your swimming pool, wash cars, wash clothes and flush toilets.
  2. Reduction of water bills – once you have installed your rain water tank you water bill will be reduced as you use less mains water.
  3. Fire protection – for those people who live in a bushfire zone, there will be the rain water tank as an extra water source during a fire.
  4. Storm water run off is reduced – as urban areas become more built-up, less water will seep into the ground which may cause flooding and drainage issues. Rain water tanks will help prevent this occurring.
