What’s the Value of a Rainwater Tank?

No Comments

A single inch of rain on a 1000 square foot roof yields 623 gallons of water. That’s a lot! Installing a rainwater tank means you can keep all that water around until you need it, thereby reducing your use of mains water, saving you money, and helping the environment. If you receive enough rain, it might even be possible to make yourself independent from the public water supply.

The environmental benefits of installing a rainwater tank in certain arid regions of the country are so great that the local authorities strongly encourage and may even require them. In Victoria, using a water storage tanks to run your flush toilets is good for an additional star to help you reach the required five stars in your house energy rating for new construction. Even when they’re not required, rainwater tanks make a great source of water for gardening, washing cars, flushing toilets, and other situations where purity is not critical. Why waste precious purified water just to wash your car?

It is even possible to use rainwater tanks as sources of drinking water. Many people feel that if it tastes, smells, and looks fine, it probably is. You should still be very careful, and ideally install a reverse osmosis or similar purification system. There are a number of contaminants and pathogens that aren’t detectable by sight, taste, or smell. Using a rainwater tank as a drinking water source therefore takes more care than just using it for washing. It’s necessary to ensure the correct types of paints are used for the roof, the tank pH is kept under control and a variety of other factors taken into account.

The Dry, the Thirsty and the Nearsighted

Want a drop of rainwater?

The title doesn’t refer to a myopic old animal withering away in the outback, but to most of us who fail to take control of the water supply in our homes.

When the continents moved and the world took its present form, for some reason we Australians must have got the short end of the dowsing stick. Our rivers are irregular as is our rainfall. Somehow, water has always managed to elude us when we need it. And sometimes it surprises us when we least expect it and sweeps us off our feet. And yet many of us fail to plan for the dry season.

If you live in Perth, you’d probably be sitting through the present historical dry spell and thinking with envy of those in Brisbane caught in flash floods. But the truth is that the east coast is not much better off when it comes to drinking water supplies – the Murray-Darling basin is drying up at a shocking rate. And there can’t be enough said about the state of our groundwater throughout the country – though the lesser said the better for a good night’s sleep.

The question is: do we really have to give in to this lack of control over our own water supply? While the authorities are grappling with the problem of restoring groundwater levels, what are we doing to help?

It’s simple really, to ensure that each family makes the most of the rains. All that we need to harvest rainwater is to have a water tank installed in our rural and urban homes. Most such tanks are poly water tanks, made of durable polyethylene, which are quite affordable. You can use the water collected for your cooking, gardens and swimming pools and even as drinking water!

So have a poly water tank installed and you no longer have to worry about the not-so-rainy seasons again!

Aussie Rainwater Tanks: Major Areas of Application

No Comments

water from tapMost urban Australians take domestic water supply for granted, completely overlooking the fact that most of our country is desert, number of fresh water resources is limited and the rainfall pattern varies greatly each season. For quite some time now, Aussies living in isolated areas have been utilizing Aussie rainwater tanks to collect water for meeting their various needs. Suppose if you were to install a rainwater tank, where could you use the water it collected? Read on to find out.

Uses of Aussie Rainwater Tank Harvest

  • Garden Watering- Irrigating gardens is perhaps the most popular use of Aussie rainwater tanks. Collected rainwater can also be used to fill a pond, a swimming pool or children’s inflatable water pools.
  • Outdoor Cleaning- You can use your rainwater harvest to wash your car or to perform any cleaning outside the house.
  • Hot Water- You can heat the collected rainwater by using solar cells to obtain 100% eco-friendly hot water supply to your taps and faucets. Water may need to be treated and filtered before it can be fed to electrical water heaters.
  • Cooling Towers- Do you have a HVAC (heating, ventilation and air conditioning) system in place that uses a cooling tower or condenser? If yes, you can use your rainwater tank’s harvest to fill these up.
  • Toilets, Showers and Cleaning- Collected water can be directed through piper to your bathroom and can be used for flushing toilets or serving bath showers. It can also be fed directly to your washing machine through a pipe.
  • Drinking Water- Didn’t we learn in school that rain water is the purest form of water? With adequate treatment within your home, a rainwater tank can be turned into potable water. However, it must adhere to the Australian Guidelines of Drinking Water as laid out by the government.

Whatever state you reside in, you will be able to use the water from your Aussie rainwater tanks for drinking (after treatment), garden watering and outdoor cleaning. Check with your local authorities for your area’s laws as well as for guidance on installing and managing tanks.
