    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)
