Incorrect - the 0.6 number is purely for personal survival. They cite the number when including plant maintenance, regolith processing, etc, as 1.2. See the article: > "The amount of water needed for extended human survival is around 0.6 kg/hr/person which includes water for consumption, hygiene, and everyday living in space (Bobe et al., 2007; Horneck et al., 2003, 2006). This estimate is based on space station living and, assuming water consumption is less in a micro-gravity environment, would increase up to 0.7 kg/hr/person to account for living with gravity. The amount required if demands from a growing colony (regolith processing, manufacturing, perchlorate remediation, plant growth, habitat maintenance, etc.) are added to human needs is estimated at 1.2 kg/hr/person."
