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.
