Students are challenged to develop an affordable and effective system to treat water for various contaminants. The team is given a problem statement that includes a description on contaminated water. Students then must research the best method for the treatment of the water and write a design paper detailing the reason they chose their process and an estimation of the cost for removal per gram of contaminants. Students are exposed to an increasingly important branch of Civil Engineering as water scarcity increases and we must make use of all sources of water.
