Zoom in on Engineering

We take it for granted every day, but clean water is one of the most important resources we have. This behind-the-scenes look at where our water comes from and where it goes after we use it gives readers a fascinating look at how our cities and towns are structured. Readers will be given a stimulating look at our sewage systems and wastewater treatment plants, which track the water through the system. A follow-up activity encourages readers to track their water usage for a week to emphasize the importance of clean water.
