This morning my YouTube subscriptions included a notification of a new TED-Ed lesson that caught my attention. That lesson is titled How the Water You Flush Becomes the Water You Drink. As the titled implies, the lesson is all about how wastewater gets cleaned and put back into the water cycle where we’ll eventually drink it once more.
The lesson introduces viewers to three types of wastewater and how wastewater is treated. The two key terms from the video are direct potable reuse and indirect potable reuse and the differences between the two. You can watch the lesson on YouTube or as embedded below. The full lesson with questions and additional resources can be found here on the TED-Ed website.
Here are some more resources and lessons related to the water cycle:

- How Many People Does it Take to Make a Cup of Coffee?
- A Handful of Lessons on the Water Cycle
