Students learn about water quality testing (coliform bacteria, turbidity) and what is involved in basic water treatment designs. Biological, physical and chemical treatment processes are addressed, as well as physical and biological water quality testing, including testing for bacteria such as E.coli.

By creating access to clean water, engineers improve human health and save lives around the world. Engineers play a vital role in keeping harmful microscopic organisms out of our water supplies and research is continuously conducted to develop new ideas to lower the energy consumption and resource needs to do this. Engineers design large- and small-scale water treatment facilities and the water distribution systems that get the clean water to our homes and industries. Describe how engineers determine water quality before deciding on water treatment options.Compare and contrast small-scale and large-scale water treatment options.Explain how water treatment technologies can save lives.20TeachEngineering.orgChristie ChatterleyKate BeggsMalinda Schaefer ZarskeJanet YowellDenise W.
