Day 1 Success: Optimize Water Usage with a Smart Starting Point 360 liters — that’s how much water remains after day one’s use, when 500 liters were consumed from a total supply of 620 liters. Rather than viewing this as an end, Day 1 can be celebrated as a strategic milestone in efficient water management. ### Understanding Day 1’s Water Consumption On the first day, a household or facility used 120 liters, leaving 500 liters remaining — a strong indicator of careful planning. Divide 500 by the daily target of 120 liters, and you get 4.16, meaning this supply comfortably supports four full days at 120 liters, with room for unexpected usage. Subtracting 120 liters confirms exactly what’s left: 380 liters.
