This year I want to work in my class uptake and distribution of water. So I want to work reservoirs and water treatment plants. Here's several pages that I will be useful to share with partners. I can only work the route of water to the house and not the process of wastewater treatment, but these pages explain the whole process.
Thank you very much.
