The water consumption of a household represents a fairly large budget year and yet very few consumers know how much water they consume per day and what expenses generates every habit of the day. It is therefore interesting to seek to calculate its water consumption to assess what will be the amount of the bill.

Calculate your water consumption: some useful numbers

Know first of all that a household of 4 people consumes around the year 150 m3. One cubic meter equals 1000 liters, so imagine how much water you can use on a daily basis. On average, a person needs each day to 150 liters to wash, clean his house, cook and hydrate. The price of water per m3 varies depending on the distributor and the region but it is important to find out in order to calculate your consumption. It is also important to know the volume of water used on average for each daily gesture.
To do the dishes, you consume between 10 to 12 liters, for a dishwasher between 25 and 40 liters, for a washing machine between 70 and 120 liters, for a shower of 5 minutes between 60 and 80 liters, for a bath between 150 and 200 liters and for flushing between 6 and 12 liters. Then will be added the water consumed for watering the garden or washing the car for example.

Methods for calculating water consumption

The first method is to bring a calculator and arm yourself with a little patience to evaluate your water consumption. Then you only need to know the price of water per cubic meter and to estimate approximately the average volume of water that you consume for each daily action. For example, multiply the number of shower you take per day by 70 liters per 365 days. You will get the number of liters you consume per year while taking your shower. Do the same with every appliance that uses water such as a bath, dishwasher, washing machine, etc.
It is also possible to go through a simulator to evaluate your consumption. The website of the International Office for Water offers you this very practical service. Just answer a few questions about the type of your home, the number of people who make up your home, your appliances, if it is your primary or secondary home... In just a few minutes, you will get a rough estimate of your water consumption and the amount of your bill.
