What is the formula used to calculate daily water requirement for showers per person?

• A. (Total # showers per week) x 17.5 gal / 7 days
• B. (Total # showers per week) x 5 gal
• C. (Total # showers per month) x 17.5 gal / 30 days
• D. (Total # showers per month) x 5 gal

Answer: (A)

The formula to calculate the daily water requirement for showers per person is specifically designed to account for the number of showers taken in a week and the amount of water used per shower. Using the first option, the calculation begins by determining the total number of showers taken per week. By multiplying this number by the average water usage per shower, which is typically around 17.5 gallons according to common estimates, you get the total weekly water requirement. Dividing this total by 7 days provides the average daily water requirement per person for showers. This method effectively converts weekly usage into a daily average, making it a practical and straightforward way to assess daily water needs based on showering habits. In comparison, the other alternatives do not accurately represent the daily calculation based on the recognized average water usage for showering. They either rely on a monthly framework without adjusting for the average daily use or fail to incorporate a weekly average, which is essential for a more precise calculation of daily needs. This makes the first option the most appropriate for determining the daily water requirement for showers on a per-person basis.
