Challenge 5:
Lunar Water

The challenge is for each team to design, develop, and test a water filter that will recycle, repurpose, and transform gray wastewater into purified drinking water for the lunar habitat. The second part of the Lunar Water Challenge will address the filtration materials themselves. Unlike on Earth, the used filter material cannot be distributed or buried. Each team will provide recommendations or suggestions describing the safest way to process the used filter material, which now contains contaminants that have been separated from the water.
