Tread lightly caravan

This morning Waitemata went the Tread lightly caravan to learn about water pollution. First we were put in to four groups. First group stayed inside the classroom and learnt about wet lands and VR head set. The wet lands help to clean the muddy water. The wet lands also slows the flow of water to stop flooding the grounds. Next my group had to use maps to find all the in our school. After that my group went to the caravan. We learn that only rain goes in the drain. Water from sink and toilet goes in waste water treatment plant to get clean. I learnt that we should put rubbish in the correct bin or it will end up in the sea and fishes will die.
