Your Usage

How to Calculate your Daily Water Use:

​

  1. Determine quarterly usage (from water bill)

 

  2. Convert ft³ to gallons by multiplying by 7.48

 

  3. Divide by the number of days in a quarter (approx. 90)

 

  4. Divide by the number of household members

Usage Calculation Example
The following is an example of a water bill for a family of five:
 

2021-06-14 20_46_37-Conservation Worksho

1. 3600 ft³ is used in this quarter

2. 3600 x 7.48 =

26,928 gallons 

(Converting feet to gallons)

3. 26,928 gallons ÷ 90 days =

299 gal/day

(Dividing by number of days in a quarter)

4.  299 gal/day ÷ 5 =

60 gal/day/person 

(Dividing by number of household members)
