Toilet water use can vary significantly. Older toilets can use 3.5, 5, or even up to 7 gallons of water with one flush. Federal plumbing standards now specify that new toilets can only use up to 1.6 gallons per flush (GPF), and there are high efficiency toilets that use up to 1.28 GPF.
Replacing an older model toilet with a new high efficiency toilet (1.28 GPF) can greatly affect your household’s total water usage. HET’s are widely available at home improvement and plumbing stores, and typically cost about $100-400 plus any installation fees. The estimated payback time for a HET typically ranges from half a year to five years depending on the cost of your toilet and your household’s annual water and sewer costs. If purchasing and installing a new toilet is not possible, you may be able to retrofit your older toilet.
The national average for a gallon of water is 2/10ths of a cent per gallon. Many municipalities also charge sewer rates based on water usage, so to compensate for that, we’ll calculate it at a rate of 3/10ths of a cent per gallon.
The average amount of water used in a flush has varied over time. Toilets from the 1950s use as much as eight gallons per flush. Over time, the total amount per flush has gone down drastically. Currently, the average toilet manufactured today uses about 1.5 gallons per flush. Since many people aren’t necessarily using brand new toilets, the average usage is two gallons of water use per flush.
So, how many times does a person flush per day? A recent AWWARF study indicates the average person flushes a toilet 5 times per day. And a survey that I saw recently indicates that the average person has 1.5 “brown” flushes per day.
Water is not used up when you flush a toilet. It is “Recycled” into the water cycle.
Where I live, water comes out of the ground. When I flush a toilet it goes back into the ground. None of the water is consumed. It is just moved from the ground to the toilet and back to the ground.
In the larger world, most water resides in the oceans. It evaporates and becomes rain. The rain finds its way into rivers and wells where it is piped to toilets and other domestic fixtures. After domestic use it finds its way back into the oceans. Again, no water is used up. It is just recycled.
The problem with water use is related to how much water is available in any particular area and how many people and other animals want to use it. In big cities there are more people than the water systems can support. This creates the illusion that there is a shortage of water on a planet that is composed mostly of oceans.
toilet flushes, achieving a savings of 15,000 gallons (56.7 m3) per year.
New, High Efficiency Toilets (HETs) use 1.3 gallons (5 liters) per flush (gpf). With an HET, a family of four will use approximately 9,000 gallons (34 m3) per year in total toilet water use. Look for the WaterSense label to ensure your new toilet has maximum efficiency and high performance.
Toilets made from the early 1980s to 1992 typically used 3.5 gallons per flush (13.2 liters) or more. Toilets made prior to 1980 typically used 5.0 to 7.0 or high gallons per flush (18.9 lpf to 26.5 lpf). The oldest toilets can use more than 8 gallons per flush (30 lpf).
How much water is used to flush a toilet in litres
New toilets will using between 6 to 10 litres of water with each flush where high efficiency toilets can go below to even 5 litres of water. The older toilets if not altered can use between 13 litres to 19 litres of water each time.

How to save water? Toilet Water Saving Tips
Using Dual-Flush Toilets
Toilets consume an average of 20.1 gallons of water per person, per day in a home with no water-conserving fixtures, according to the American Waterworks Association. That’s nearly 30 percent of an average home’s daily per-person indoor water use. Upgrading from a 3.5 gpf (gallons per flush) toilet to a 1.6 gpf model will reduce one person’s annual water use from 27,300 gallons to 12, 500 gallons, according to the Federal Energy Management Program.
The dual fluch technology was first developed in the 1980’s, the dual-flush toilet takes water-efficiency one step further: using 1.6 gallons for solid waste and only .8 gallons for liquid waste.
What kind of savings can expect u with a dual-flush toilet?
Reduce water usage up to 30%. Total savings depend, of course, on frequency of use. You’ll also save on sewer costs, because they reduce the load on the waste system.
But our topic today, toilet flushing, requires between1.5 and five gallons per flush, depending on the age of toilet one uses. Combined, the typical American flushes away 24 gallons of water each day, nearly a quarter of our total water consumption.
We don’t naturally quantify all that flushing in dollars and cents, but like everything else in life, toilet water costs money. The OGWDW estimates that the average cost of water is $2 for 1,000 gallons, or, approximately 4.8 cents per person, per day, for 24 gallons of toilet water.
In total, the roughly 300 million Americans spend more than $5 billion dollars a year flushing their toilets.
