What This Calculator Does
Estimate household water use from showers, laundry, and daily routines.
It combines Shower Length, Showers per Week, Toilet Flushes per Day, Laundry Loads per Week to estimate Weekly Water Use, Daily Average, Weekly (liters).
Formula & Method
Notation used in the formulas: R = Weekly Water Use; x_{1} = Shower Length; x_{2} = Showers per Week; x_{3} = Toilet Flushes per Day; x_{4} = Laundry Loads per Week; x_{5} = Dishwasher Runs per Week; x_{6} = Faucet Use per Day.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
