Question 5

What size water tank do I need?

Accepted Answer

To determine the right tank size, start by calculating your roof catchment area and checking your region's average rainfall.

You can use our ‘Water Catchment Calculator’ TBC LINK to estimate how much water you can collect annually.

As a general guide, a family of four with a small garden typically uses around 280,000–300,000 litres per year for everyday household use.

It’s always better to go a little bigger – after all, no one ever regrets having extra space!
