Did You Know ...
- For a single-family residential family, the average water use per day is 69 gallons per person per day. For a
household of two people in a 30-day billing cycle, that calculates to 4,140 gallons of water used per month. An average
consumer in our area uses 4,500 gallons of water per month.
- Conventional washers from the 1980s use 48 to 55 gallons per load.
Washers from the 1990s use 39 to 43 gallons of water per load.
Full-sized high efficiency washer uses 18 to 25 gallons of water per load.
- A water efficient dishwasher uses 7 gallons per load.
Dishwashers manufactured before 1990 use about 14 gallons per load.
- Since 1992, new faucets use a maximum of 2.2 gallons per minute at
60 lbs per square inch. Installing aerators can save up to one-half the amount of water used. Faucets without
aerators can use up to 7 gallons per minute.
- Showers installed in the 1980s use 3 to 4 gallons per minute and pre-1980
showerheads use 5 to 8 gallons per minute. Since 1992 in Texas, new showerheads must use a maximum of 2.5 gallons per
minute at 80 lbs per square inch (this calculates to 25 gallons of water for a 10-minute shower built after 1992).
- Toilets manufactured before 1980 usually require
5 to 7 gallons per flush. Models installed in the 1980s use around 3.5 gallons per flush. Since 1992 in Texas,
new toilets must use no more than 1.6 gallons per flush. If you replace a 3.5 or 5 gallon toilet with a newer toilet
manufactured after 1992, you cold save about 9,740 or 17,300 gallons of water per year. If you have a pre-1992 toilet,
water can be conserved by installing displacement devices such as a plastic bottle or bag into the tank.
- Washing Hands where you leave the water running, uses 1/2 gallon of water.
