How is water conserved on a space station?

Water is conserved on a space station through a combination of recycling and careful management. The International Space Station (ISS) uses advanced water recovery systems that purify wastewater, including urine and sweat, to reclaim nearly all usable water. Additionally, astronauts practice efficient water usage in daily activities, such as using rinseless wipes for washing and minimizing water use during food preparation. This closed-loop system ensures a sustainable supply of water for the crew.
