Install a rainwater tank to collect and store rain hitting your roof and use it to water your garden, wash your clothes or fill your toilet.
By capturing and using the rain that falls on our houses - water that currently flows into the stormwater drain - we are taking another step in increasing our water efficiency and conserving this precious resource. Have a plumber redirect your down pipes into a tank for storage and install pumps and pipes to service some of your household water needs. By these simple actions, most Australian households would save at least 45,000 litres and hundreds of dollars each year.
Investigate the benefit of installing a rainwater harvesting system in your home, explore government rebates and think medium to long term.
Potential estimated average annual capture amount (KL) = roof area (in square metres) x average annual rainfall (in millimeters)/1000
The Alternative Technology Association has developed Tankulator, a useful online calculator for determining the optimum water tank size for your specific location, roof area and usage profile.
For example, a roof area of 250m2 is an area that receives annual rainfall of 600mm will be able to capture 150,000 litres per annum. Assuming the rainfall is spread evenly over the year, i.e. 12,500 litres per month, and regular use of this water is in toilets and garden watering, a 25,000 litre capacity tank may be sufficient to maximise water capture. However, if the rainfall pattern over the year was more skewed to certain months (i.e winter) then the tank size would need to increase to store more water for the dryer periods.The Bureau of Meteorology website list the annual, monthly and seasonal rainfall averages for most parts of Australia.
Developing an understanding of your monthly average rainfall capture will enable you to identify what sized tank will maximise your rainwater capture and reuse.
In addition, a recent study by Energy Partners in Canberra found that a one-star improvement in a home's energy rating coincides with an average increase in advertised sale price of around $15,000. Therefore, the above investment will add at least $10,000 of value to your house should you sell. This equates to a 5.5 per cent annual return plus your investment back.
Fresh water is the lifeblood of nature. Without it, we would not have clean air, food, drink and many aesthetic and recreational benefits. Therefore, we need to ensure we use water in a sustainable way - we need to share it with all life on the planet and respect and value this "lifeblood". The consequences of doing otherwise can be seen in the spreading deserts across the world and the drought and famine that can soon follow.
Many rivers and wetland systems in Australia are under stress from human withdrawal of water. River red gums, fish breeding stocks and the estuary systems at the end of these rivers are dying. The human need for water is continuing to expand in the face of this silent death of our rivers. This action moves us toward being as efficient with our water use as nature is. A tall order indeed.
Clean fresh water from the tap is, for most people in the world, a luxury. As the Australian water supply is stretched, recycled and sterilised at the expense of our waterways we expose ourselves to toxic algae, chemically treated water and an increased vulnerability to severe drought. Many people across the globe are not so lucky, and a lack of water and associated diseases kills tens of millions of children each year. So water wisely, and conserve this precious resource.
