Earth, viewed from the International Space Station (photo courtesy of NASA) Did you know that an astronaut on the International Space Station uses less than one gallon of water per day? Astronauts have to conserve water, because transporting and storing water in space is expensive and difficult. Space travel is also a critical example of how water reuse--that is, the reclamation of wastewater through advanced treatment methods to make it usable again--can be a solution to water supply issues on Earth. In the coming years, water reuse will play an increasingly important role in addressing water issues, particularly in places where water is in short supply. However, educating the public about the importance of reclaimed water will be a significant challenge. Water education enables people to embrace new solutions to water issues.

Last year, water reuse expert and Project WET Board member Dr. Alan Rimer wrote a blog post about how water is used and reused on the International Space Station, while his fellow Board member, NASA Astronaut Ricky Arnold, was spending six months on ISS. You can read that post here.

Our options for addressing critical water issues expand when we #teachwater. Help us continue to reach people with objective, science-based water education. Please donate today to our first-ever crowdfunding campaign on Classy.org.
