Water – How to calculate the monthly water usage

water

In terms of water usage, how much is 10 cubic meters of water?

I ask this because I live in a small apartment with another person and our monthly water bill is now over 6 times higher. When I called the water company, they tell me that they give me 10 cubic meters of water per month, and during the last bill we used 29 cubic meters of water (almost triple the allowed use).

Nothing in our water usage has changed, so I guess my question is how much is 10 cubic meters of water in terms of showering, doing laundry, etc?

In our case, we both take two showers per day and we do laundry once (sometimes twice) per week. But nothing else has changed.

1 cubic meter is 1,000 liters of water. 1,000 liters is about 264 gallons. You are allotted 10 cubic meters or 2,640 gallons, which is quite a lot.

The Average American Shower is about 17 gallons. 4 showers per day times 31 days is 2,108 gallons of water. Your worst case scenario for Washing Machine Water Usage is about 25 gallons, at 6 times per month that would be 150 gallons. Also, consider that a toilet flush is about 2 gallons. If you flush twice per day that's another 125 gallons of water. You can figure about that much for typical hand washing, etc. At this point you are at about 2,500 gallons (9,463 liters). That's roughly about what you are allowed to use.

  • Do you have a separate water meter? If so, record the reading. Take another reading the next month and get the difference, multiply by what the meter calls for to determine your usage.
  • Turn all of the water off in your apartment and go see if the meter is spinning. If so, you have a leak somewhere.
  • Check to make sure the toilet flapper is not allowing water to run after you flush. This will make the toilet keep trying to fill.
  • Do you have any water dripping at faucets or underneath the sinks?
  • Check your dishwasher settings.
  • Change the aerators in your shower and sinks.

Anything you can do to reduce your water consumption will ultimately lower your bill.
