    Study Notes

    Household Water Use

    • The global water scarcity is a critical issue with significant consequences for future generations.
    • The formula to calculate daily water consumption is DWC = WCR × N, where:
      • DWC is the daily water consumption in liters.
      • WCR is the water consumption rate per person (liters/day).
      • N is the number of people in the household.
    • The formula to calculate weekly water consumption is W = DWC × 7days, where:
      • W is the total water consumption for one week (liters).
      • DWC is the daily water consumption in liters.
      • 7 is the number of days in a week.
    • The formula to calculate monthly water consumption is M = W × d, where:
      • M is the total water consumption for one month (liters).
      • W is the total water consumption for one week (liters).
      • d is the number of weeks in a month (approximately 4.33 weeks).
    • The formula to calculate yearly water consumption is Y=M1​+M2​+...+M12​, where:
      • Y is the total water consumption for the year (liters).
      • M1​,M2​,...,M12​ are the weights of water consumed in each month.
    • The formula to calculate the amount of water wasted is Wasted Water = DWC − (OC × N) where:
      • Wasted Water is the amount of water wasted per day (liters).
      • DWC is the total daily water consumption (liters).
      • OC is the optimal water consumption per person (usually 50 liters/day).
      • N is the number of people in the household.

    Data & Assumptions

    • Data required for the model:
      • Daily Water Consumption (DWC)
      • Number of People (N)
      • Optimal Water Consumption (OC)
    • Data collection methods:
      • Household Water Meters
      • Research on Optimal Water Use
      • Surveys
    • Model assumptions:
      • Consistent Water Use
      • Uniform Water Needs
      • No Major Water Leaks

    Water Conservation

    • The World Health Organization recommends 50 liters/day per person for basic needs.
    • Water-efficient technologies, such as low-flow faucets, showerheads, and dual-flush toilets, can significantly reduce water consumption, sometimes by 20-30%.
    • By 2050, one in four people will be living in a country with chronic or recurring water shortages.
    • Adopting water-saving technologies can save thousands of liters of water daily, easing the pressure on water supplies and improving overall efficiency.
