We all know that average eight glasses of water we need to drink in a single day. However, are you think that on average the “water footprint” of an American is 32,911 glasses per day, means 751,777 gallons of water per year (Source: The Nature Conservancy). You worried like me that, how a man can consume so much of water in a day. 96% of this water is ‘Hidden Water’ used to grow and makes things we eat, wear and indoor use and to generate electricity.
Recent days we talk more about water especially conservation of water because earlier we have an idea that the source of water is abundant. However, different studies say that only <1% of water is fresh and usable for humanity. Worldwide, about 1 billion people have no access to any drinking-water source. As a result, 1.6 million people die every year from diarrheal diseases (including cholera), of which 90% are children under 5.
So, before thinking about conservation of water, we have to know how much water we use on average per day. According to USGS, estimate vary, but an average American uses 80-100 gallons of water per day mostly for bathing, toilet flushes, dish-washing, and cloth washing.
How Much Water Does The Average Person Use Per Day
- For a full tub bath required about 36 gallons of water
- By taking a shower instead of the tub may save a bit of water
How Much Water Does a Shower Use
- Old days shower uses water 5 gallons per minute
- BY using water saving shower, it reduces up to 2 GPM. Average an American take shower for 8-10 minutes in a day.
- Old faucet using about two gpm. of water
- New water saving faucets use <1 gpm. By turn off the tap during brushing, you may save little more water.
- Vary 6 -16 gallons per batch. Older model required 16 gallons of water per load.
- For newer energy star appliances use 6 gallons or less per wash. Energy Star appliances also save lots of electricity.
- New model dishwasher required less cycle to wash than old one. Shorter period means they use less water and less energy.
Dishwashing by hand
- About 8 - 27 gallon. It depends on individual hand efficiency.
- Newer kitchen faucet used only 1.5 - 2 gallons of water. To save more water and bill one can practice efficient hand dish-washing techniques.
- Old model cloth washing device uses about 40 gallons of water per load.
- Newer models use 25 gallons of water per load as well as save electricity bill.
- Older model use about 3 gallons of water per flush
- New toilets use less than 1.6 gallons per flush. If you flush 6 -8 times in a day it required about 12 gallons of water. By avoiding flushing waste in a toilet, you may reduce water use.
- Hand/face/shaving/foot washing requires about 1 gallon of water per use
- By using faucet head aerator, it can reduce further. Also by stop and run the faucet as per your need, you can save some more extra water.
- For drinking an adult person required eight glasses in a day. One glass equal to 8 oz.
- Besides this, you may need water for cooking and pet animals which is not count here.
- It depends on the force of your outdoor faucet (usually two gpm.) and size of your lawn.
- You can store rainwater and use them for lawn and garden watering. Also, you can use recycled grey water (shower, kitchen or laundry waste water) for the same to save water use and bill. For rainwater harvest or use of recycled grey water, you may take expert help from your local municipal authority.
From the above chart of water use, we may conclude that in an older version of water faucet and appliance you required about more than 200 gallons of water per person per day, whereas if you use new improved faucet head and devices you need about 80 -90 gallons of water per day.
Producing hot water by using water heater is the significant contributing household cost for an American, vary it about 14-18% of utility bills. As per energy.gov, the average American household spends $400-$600 on water heating besides $300 on water bills.
By installing an energy star Tankless water heater, you could save hot water uses as well as protect your dollar and environment by emitting less greenhouse gas.
Water is playing a significant role in our survival. Starting from brushes our teeth, taking a bath at morning water required to cooking and growing our daily foods, local business or industry, fire-fighting, municipal parks, public swimming pools, cooling of nuclear plants all need lots of water.
Here we have shown a graphical presentation of daily water use for indoor purposes for better understanding.
Average Household Water Usage
Whenever we required water, we use just pressing the water tap. However, are we think a while that from where the water comes? How much water usable for us? The primary sources of fresh water are our local lakes, rivers, streams and or into underground aquifers. However, due to environmental pollution and the continued draw down of groundwater, the source of fresh water become scarce.
In research, the Conservancy scientist Brian Richter has shown that every year at least one month 2.7 billion people suffer from water scarcity.
How Much Water Does The Average Person Use
So, its time comes to take a step to save our precious water. By using new high-end appliances like faucet head aerator, energy start dishwasher or tankless water heater, you can contribute to conserve water, energy and reduce greenhouse emissions thus save your monthly expenses.
