Average Water Usage

Using a washing machine and flushing the toilet are the two main usages of water in your home. While, shower usage comes in at third. 

Research has shown that showers use around 2.1 gallons of water every miniature that they are in use. While the average length of a shower has been discovered to be around 8.2 minutes.

Therefore, if you time together 2.1 with 8.2, an average shower uses around 17.2 gallons of water. With a 10-minute shower using around 21 gallons of water. 

However, a lot of people will have at least one shower a day. This can calculate up to 7 showers a week minimum.

Therefore, your weekly water usage just from your shower alone by just taking one shower a day could end up with 120 gallons of water per person.

Thus, this can amount to 6,261 gallons of water per person every year.

Although, some people may sometimes have two showers a day and this will then increase the number even more.

  • Flow Rate – The flow rate of your shower is going to affect how much water you are using. It all depends on how fast and the amount of water that is coming out of your shower head. The flow rate of your shower head is important as this will affect your water usage

This small amount will really add up, and you could end up saving on 100s of gallons of water every year. This will then also have a huge impact on your water bills too. 

Try the navy shower, where you turn the water off while you soap up your body and apply shampoo. Then switch the water back on to rinse all the soap away. You can then dramatically cut down the time of your shower, by up to 5 minutes. 

Also, as you are limiting your time, try to reduce how many showers you are taking. Do you really need to take a shower every day? Normally, people can go at least one day without taking a shower.
