Indoor Water Audit

Find out how many gallons of water your house uses, then save water and money by following these simple steps.

  1. Read your water meter before using any water. See also Meter Reading & Leak Repair »
  2. Keep track of all indoor water using activities for one day (24 hours).
  3. Determine the number of gallons each water using activity uses from the WATER USE ACTIVITY CHART below.
  4. Read your water meter after one day (24 hours) and verify your calculations.
    (FOR WATER METERS MEASURING IN CUBIC FEET: 1 CUBIC FOOT = 7.5 GALLONS.)
  5. Calculate the per-person consumption rate.
    (TOTAL GALLONS OF WATER USED DIVIDED BY TOTAL PEOPLE LIVING IN HOME.)

EXAMPLE:

Beginning Meter Reading* = 1000
TOTAL USE = 303 gal/person Rate
Final Meter Reading* = 1303
303 gal/3 people = 101 gal/person

USE BROKEN DOWN BY AREA AND APPLIANCE:

Bathroom:
  • Toilet: 18 flushes x 5 gal/flush = 90 gal.
  • Sink: 6 minutes x 3 gal/min = 18 gal.
  • Shower: 25 minutes x 5 gal/min = 125 gal.
Kitchen:
  • Sink: 6 minutes x 3 gal/min = 18 gal.
  • Dishwasher: 1 cycle x 15 gal/use = 15 gal.
Other:
  • Laundry: 1 cycle x 37 gal/use = 37 gal.

Note* If the beginning meter reading plus total use do not equal the final meter reading, you either used water outdoors and/or you may have a leak.
