Plan Your Rainwater Tank The Right Way

Harvesting Rainwater is becoming mandatory, and rainfall varies from place to place.

Our Calculator sizes your tank to your roof and your location's own rainfall record.

How it works

Three steps to your tank size

Step 1

Find your area

Use your location or pick your city and area from the list. We look up real rainfall data for that exact spot, from nearby weather stations and satellite estimates.

Step 2

Describe your house

Tell us your plot size and roof area. Don't know your roof size exactly? We'll suggest one based on your plot.

Step 3

Get your tank size

See how many litres your roof can collect in a year, and a tank size to match, with a few shapes to choose from.
