Water - every drop counts

Follow the journey of water from a river through to your tap at home. See how water is treated to make it safe to drink and think about your own use of water.

Water treatment.

Watch the video to see how water is treated at the Wainuiomata Treatment Plant in Wellington.

Ponder this 

Consider the following questions. You could talk about your ideas with your favourite people at home or online.

  1. What are the main stages in water treatment shown in the video?
  2. Where does your drinking water come from? Is it treated in the same way as in the video?
  3. At home we use drinking water for many different things. Name all the different things you use water for? 
  4. Why do you think we need to be careful about how much water we use?


Read the background information on water use. Using this information, estimate how much water you use per day at home. How could you test the accuracy of this estimate?

How could you reduce your use of water? What are the benefits of using less water?

Share your ideas in a poster, drawing or photo. Ask a parent to post a picture on Instagram. Use the hashtags #learnztrips, #conservewater, or email a photo to LEARNZtrips. Tell us about your discoveries. 

We’ll share some of your images on our Instagram space @learnztrips.

Water is essential to life and sacred to Māori. Every time you use water there is a story about where it came from and another story about what happens to the remaining wastewater. Join us in Wellington as we trace the journey of fresh water. Discover more about drinking water, stormwater, and wastewater.
