How much raw (fresh) water is brought into the drinking water treatment facility?
How much treated water is put into the distribution system?
These values should be given in units of volume/time.
You have calculated the water footprint of your community and its tap water using real information that you found from your research but you may now be wondering how different these footprints might have been if some things in your community or at your treatment facility were different. You can use the calculations process you learned to test different changes and see how they could affect your footprint values.
