They're usually less expensive and cut down significantly on the amount of water used. Flush the toilet less often. In most cases, several uses can be made of the toilet for liquid wastes before flushing. Take shorter showers. Get wet, turn off the water, lather up, then turn on the water to rinse.
Showers require less water than tub baths.
Every inch in the tub equals approximately 5 gallons. Up to five gallons a minute goes straight down the drain when taps are left running to shave or brush teeth. Turn on the taps only when needed. When washing dishes by hand, fill a basin or use a stopper in the sink for rinsing rather than running the faucet. Automatic dishwashers use 12 to 25 gallons for each full cycle, so avoid using the rinse only cycle and washing small loads.
