The Tankulator is a free online rain harvesting calculator that can help you plan for a new rainwater tank or improve the performance of an existing tank.

The Tankulator has been developed by the Alternative Technology Association, Australia’s leading not-for-profit organisation promoting sustainable solutions for the home. Click on the Get Started button, fill out the online questionnaire then click on the Get Tankulating button. An interactive graph will appear that will display your calculations.

Once the calculation is complete, you can compare different scenarios to find the best match for your circumstances. Will you run out of rainwater in a dry year if you live in Canberra and plumb a 10,000 litre tank to your toilet and laundry?

Buying a rainwater tank?
  • Tank Materials: Compare the cost, environmental impact, life span and other specs of different types of tank materials. Hear what ATA members say about the tanks they have chosen.
  • Tank Siting and Installation: What will fit on your property and where to put it? Pros and cons of different approaches to placement and installation of your tanks.
  • Tank Filtration: What kind of filtration do you need on your system? What degree of maintenance are you willing to undertake?
  • Pumps: Most rainwater systems will need a pump; what do you need to know? Also, pumps can use a lot of energy but there are ways to design your pumping system to reduce energy use.
Visit the Tankulator website to find out more.

A free online seminar on rainwater harvesting and greywater will be held by the ATA on Tuesday, November 8 at 11am. Visit for more details.

10,000 Raingardens Program: Add yours to the list

Posted in Movements, Research by Kate Archdeacon on September 20th, 2011

Melbourne Water’s 10,000 Raingardens Program promotes a new, responsible way of gardening so everybody can create their own water sensitive garden and do their bit to help the environment and protect our rivers and creeks.

The aim of the program is to show you how easy it is to create a water efficient garden in your own backyard. By building a raingarden you will enjoy the benefits of a self watering, low maintenance garden while also contributing to healthier waterways by reducing the amount of pollutants that would otherwise wash into our rivers and creeks. Until now we have been working with local councils and the community to create raingardens in public spaces such as streets, parks and schools. The program has recently expanded and we are now providing easy, step by step instructions so people can design, build and maintain raingardens in their own homes. Our target is to see 10,000 raingardens built across Melbourne by 2013. To achieve this we need your help.

>>Find out what a raingarden is, why you should build a raingarden and how to build one.  (And then add yours to the Map!)

Sustainable Shoppers Guide to Rainwater Tanks

From Cuttings, May 2010:

As summer becomes a distant memory and the weather begins to cool, many of us have been privy to an unusual phenomenon… rain! With all the wet stuff about, and some governments altering their water restrictions, we do tend to forget about water conservation and rain water harvesting… but, let me assure you, this is the time to think about it, not just in the warmer months! In fact, autumn and winter are excellent times to seriously consider installing rainwater tanks. If you have a rainwater tank in place now, think of all the H2O you’ll have ready to go come spring … it’s kind of like a ‘layby lifeline’ for your patch!

But with the huge range of tanks out there, heading out to buy a tank can be incredibly daunting. Luckily, SGA have come to the rescue, and have put together a ‘Sustainable Shoppers Guide’ to help you make the right rainwater decision for your place. So here is a swag of information on a number of commonly used, currently available rainwater tanks and their features, be they good, bad and ugly. Bear in mind that new products are released all the time, so, if the tank you are interested in ain’t on the list, just let us know, or pop on the forum and have a yarn!

Oh, and remember, with all tanks, it is recommended that you get a licensed plumber to install your tanks… it’s the only way to claim any Government rebates on the purchase price of your water holding wonder!

Go to “Tanks A Lot – The Sustainable Shoppers Guide to Rainwater Tanks” to see the results.
