Laundry water is priced in thousands of gallons and used in loads, so the cost stays invisible.
Turn loads a week, gallons a load, and the water rate into a week, year, and per-load cost.
Anyone comparing laundry habits with the water and sewer line on a utility bill.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Count the loads in a normal week. Include every wash, not only the large ones.
Check the machine manual or the EnergyGuide label for gallons per load.
Open the utility bill and find the cost per 1,000 gallons. Add the sewer charge if the bill lists it.
Keep loads full. A full load moves the same gallons as a half load.
Compare the yearly figure with the load count. Decide changes after you see both.
You run 5 loads a week at 20 gallons a load, and water costs $8.50 per 1,000 gallons. The estimate is $44.20 a year.
Use your own source and details. The example is not a record about a real person or organization.
