Rain Water Harvest Calculator

We have put together a calculator to hep you to determine how much water you can catch each year into your rainwater tank. Use the map below to determine your rainfall zone and then scroll down to the calculator below and enter the area of total roof catchment area you have available (Length and Width) and select the tank size you are considering and your rainfall zone. This will show you how much water you can potentially catch from your water tank, and also how much additional water you would catch in the event you choose to add our water collecting Gutter System to your tank package.
