Title: Sustaining Life on Mars: How Efficient Water Recycling Supports a Colony’s Survival Meta Description: Discover how a Martian colony recycles 85% of daily water use—only needing fresh imports after 7 days—to maintain sustainable life on the Red Planet. --- In the harsh environment of Mars, every drop of water is a precious resource. With no natural reservoirs and limited supply chains from Earth, colonies rely heavily on advanced water recycling technologies to survive. A recent breakthrough by a Martian settlement shows remarkable efficiency: their water recycling system recovers 85% of daily used water. But how does this tecnology impact the colony’s need for new water imports over time?
