Renew's free online calculator helps you plan for a new rainwater tank or improve the performance of an existing tank

Rainwater for your site

With so many different water tanks and water management systems available today, how do you choose the one that will meet your needs?

With climate change creating uncertain rainfall patterns, rainwater tanks are a simple solution with measureable benefits for most Australian homes. So what tank and system is best for you?

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

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?
