Wavy’s Drip Drops
Let’s think about how we can save water around the house.
Ask your parent or carer for a copy of your latest household water bill.

Yarra Valley Water recommends a target of 155L of water use per person, per day to help secure water supplies for current and future generations of Victorians. Was your household above or below that target in the latest billing period?
You use X amount of water in your home in a single day. Let's try to estimate where in your home you use this water, based on your answers in your other challenges.
