Converting Decimals to Fractions Play Battleship with Fractions, Measurement, Whole Numbers, and Decimals Create A Graph ## The Down the Drain Project## How Much Water Do You Use?How much water do you use everyday in your home? Would you be surprised to learn that according to the USGS the average American uses between 80-100 gallons (approx. 300 - 375 liters) of water per day? Do you think people in other parts of the world use more or less water than Americans? Well, this collaborative project will help you find out the answers to these questions. By collecting data on water usage from people around the world you will be able to see how your water use compares to others and determine what you might do to use less water. http://www.k12science.org/curriculum/drainproj/instructions/
Unfortunately, these appliances use a lot of water to do their dirty work. And when drought plagues, we worry that the toilet is flushing away too much of a valuable commodity. Most people don't realize how much of our water toilets hog. After outdoor irrigation, toilets consume the most water in a residential home. Flushing a toilet accounts for 14 percent of the water used both inside and outside a home [source: Alliance for Water Efficiency]. And if you measure only indoor appliances, the percentage of water used by toilets goes even higher. Flushing a toilet uses 38 percent, or more than a third of the water, utilized indoors in the typical U.S. home [source: Massachusetts Water Resources Authority]. Enter the low-flow or low-flush toilet. Since 1992, U.S. law has mandated that new toilets sold in the United States be low-flow or low-flush, which means that they consume no more than 1.6 gallons (6 liters) per flush. Before that time, typical toilets sold in the United States used 3.5 to 7 gallons (13.24 to 26.5 liters) per flush.
Federal regulations mandate new shower heads flow less than 2.5 gallons per minute with a line feed pressure of 80 pounds per square inch. Although actual consumption varies with water pressure at the shower head inlet and the exact flow rate of the shower head, a reasonable average for a 5 minute shower using a low-flow head would be 7-8 gallons of water. This is because most homes have far less than 80psi line pressure, the typical pressure being around 50psi. Older high-flow or unrestricted shower heads in systems with more typical 50psi water mains pressure can flow over 4 gallons per minute. A 5 minute shower would use 20 gallons of water with an older unrestricted shower head, although it could be more.
An average 5ft bathtub can hold 60 gallons of water before it begins to over flow.
The average water use per dishwasher cycle decreased from a range of 11-15 gallons per normal cycle in 1978 (Garrett, 1978) to 6-10 gallons per normal cycle in 2000 (Soap and Detergent Association [SDA], 2000). Despite the fact dishwashers are designed to be resource efficient, other significant determining factors on resource usage are the result of decisions of the consumer.
According to Consumer Report and the California Energy Commission Consumer Energy Center, a typical load of laundry uses approximately 40-45 gallons per load.
## High-Efficiency WashersFront-loading washers have a door for the laundry at the front, like a dryer, and they tumble the clothes through the water similarly to how a dryer operates, too. These are considered high-efficiency washers in part because they don't need as much water as older washers; some top-loading washers are also designed specifically to be high-efficiency washers. Both types use around 15-25 or 30 gallons of water, though some are capable of less.
