Can We Save The World ?
Reduce residential water use
Some 3% of US Energy is used to provide residential water and sewerage services. In recent
years water has sometimes become scarce. The less water you use the less energy your water
supply company will use.
60% of water used in US residences is used
outside our homes.

In the US we use 40% of residential water in our homes, toilet flushing uses 30%, clothes
washing 25%, showering 20%, faucets 18%, bathing 2%, dishwashers 2% and others 3%.
We need to change our attitude to water to regard it as a precious resource, and to conserve it.

In the US most of us use far more water than we need to, we waste water and cause water restrictions.
However reducing our water use is quite simple and will dramatically reduce our water costs.
What can I do to reduce water use in my home and conserve water:
By using the above suggestions you can reduce your residential water use by more than 70% and conserve water.
- Reduce toilet water use, they use about 30% of the water used in homes.
- Donít flush the toilet on every visit, 'if itís yellow let it mellow' at least until a next
visit, 'if itís brown flush it downí. By flushing on average every second visit an average home
can reduce toilet water use by 6,000 gallons per year!
- If you have a toilet that uses more than 2 gallons per flush install a water displacement device
or a toilet displacement dam, these reduce the amount of water used per flush.
- Reduce toilet water use by installing a new low flush toilet, these use around 1 gallon on a
half flush or 1.5 on a full flush, older toilets used up to 6 gallons.
- Use less water when you bath, have a short shower instead.
- Use less water showering:
- Have fewer showers, keep your bodies protective oil on your skin.
- Have shorter showers and turn the water off when lathering with soap or shampoo, this will
also reduce the energy used to heat your water.
- Fit a low flow shower head.
- Use power showers extremely frugally, a power shower running for 5 minutes can use as much
water as a bath!
- Consider replacing your old washing machines and dishwashers with newer models. Newer models
save both water and energy. Modern washing machines reduce water use by more than half and use
less than half the water that is used when washing dishes by hand. When using a dishwasher donít
rinse off dishes first, just scrape off excess food.
- Donít let the faucet run unnecessarily when washing, shaving, washing dishes, and when washing
fruit and vegetables. Use a plug in the sink or a bowl rather than washing under the faucet over an
open plug hole.
- Fix leaks, 6% of residential water is wasted by leaks. A dripping faucet can waste 20 gallons
per year. Leaks are most common in toilet cisterns and faucets. If you have a water meter, you can
check for leaks by turning off the water and taking two meter readings an hour apart. If the
reading is different, there may be a leak, leaks more often occur in supply pipe work below or
adjacent to your premises.
- Most of the suggestions under

reduce water use.
- Fill kettles with just enough water for your needs, this will also reduce your fuel bills.
- Recycle water used for washing, use it in the yard, recent research shows it does not harm plants.
- Install aerators to faucets used for washing, these reduce flow to 2 gallons per minute.
- Install a rainwater storage system. Filtered and stored and pumped rainwater can be used
throughout your home, with the exception of cold water faucets that provide drinking water, dramatically
reducing residential water use. The author has had a rainwater storage system in his home for the
past 9 years, it has worked flawlessly, the only maintenance that has been required is to clean the
- Install a grey water recycling system, this reclaims washing water for use in the toilet and
yard irrigation. Grey-water is wastewater from washbasins, showers, baths and from cooling processes.
- Ensure that everyone in your home is aware of the need to be water efficient.
